Not sure if you’ve ever had the pleasure of experiencing the tub of miracles otherwise known as rainbow chip frosting. It’s a tangy-sweet, but mostly sweet, vanilla frosting that has soft and colorful chips swirled inside. If unicorns and leprechauns owned a bakery together, rainbow chip frosting is what they would sell. But in real life, it’s sold in the baking aisle, so let’s make our own at home!

Overview: How to Make Rainbow Chip Frosting

For the full recipe, scroll to the bottom of this post.

  1. Melt the white chocolate. Use a double boiler or microwave. I recommend Baker’s or Ghirardelli brands of white chocolate. They’re sold in bars in the baking aisle, typically right next to the chocolate chips.
  2. Add color. Pour the melted white chocolate into 4 bowls. Add 2-3 drops of food coloring to each. I like to use Americolor gel food coloring (affiliate link). Don’t use too much food coloring– this can cause your white chocolate to seize up.
  3. Spread the chocolate onto baking sheets. Line each baking sheet with a silicone baking mat or parchment paper. Refrigerate for 15 minutes.
  4. Make the frosting base. Beat the butter and cream cheese together until completely smooth and creamy. Add the confectioners’ sugar, then vanilla extract and salt. Set aside.
  5. Chop the white chocolate into “chips.” Remove the white chocolate from the refrigerator, place white chocolate rectangles on a cutting board, and chop it up into tiny squares or pieces. Fold a big handful of chips into the frosting using a rubber spatula. You’ll have a few chips leftover– great for decorating the cake/cupcakes/whatever you’re making!

You can use any color you like, but stick with just 4 because you won’t have enough white chocolate for more.

Spread the colors out onto a silicone baking mat or parchment paper, refrigerate for about 15 minutes until solid, then cut into little tiny pieces.

Description

Homemade sweet and creamy rainbow chip frosting tastes even better than the real deal!


Ingredients

  • 6 ounces (170g) pure white chocolate, coarsely chopped*
  • food coloring: red, green, yellow, blue
  • 3/4 cup (1.5 sticks or 172g) unsalted butter, softened to room temperature
  • 6 ounces (170g) brick cream cheese, softened to room temperature
  • 3 and 1/2 cups (420g) confectioners’ sugar
  • 1 and 1/2 teaspoons pure vanilla extract
  • salt, to taste

Instructions

  1. Melt the white chocolate. Use a double boiler or microwave. If using the microwave, stop and stir the white chocolate every 20 seconds to help avoid seizing. Pour the white chocolate into 4 small bowls and stir in 2-3 drops of coloring to each. Don’t use too much food coloring, as your white chocolate will seize up. Spread chocolate out onto a silicone baking mat (recommended) or parchment paper-lined baking sheet. You’ll have 4 rectangles. Refrigerate for 15 minutes.
  2. Meanwhile, get started on the frosting base. In a large bowl using a handheld or stand mixer fitted with a whisk attachment, beat the butter and cream cheese together on high speed until completely smooth and creamy, about 3 minutes. Add the confectioners’ sugar 1 cup at a time, beating on low at first then increasing to high speed. Once incorporated, add the next cup. Once creamy and combined, beat in vanilla extract. Taste. Add a pinch of salt if you’d like. Set aside for a moment.
  3. Remove white chocolate from the refrigerator. The rectangles should peel easily off the silicone baking mat. Chop up into tiny squares or pieces. Fold a big handful of chips into the frosting using a rubber spatula. Add more if desired. You’ll have a few chips leftover. (Would be great for decorating the top of the cake/cupcakes/whatever you’re making!)
  4. Store any leftover frosting or chips in the refrigerator.

Notes

  1. Make Ahead Instructions: You can make this frosting 1 day before you need it. Keep it covered tightly in the refrigerator until ready to use.
  2. White Chocolate: I recommend Baker’s or Ghirardelli brands. They’re sold in bars in the baking aisle, typically right next to the chocolate chips.
  3. Adapted from Not Without Salt.

  1. I love that you posted something from my childhood. That was a very creative thing you did!
    I want to know, are you keeping that turtle your dog found? (the pic you tweeted) how cool of a thing that you discovered!

    1. No, we aren’t keeping him. There are a lot of box turtles around where we live! Not the first we’ve seen 🙂

  2. I couldn’ t wait to make this frosting after seeing it posted on your site early Mon morning. I baked your yellow sheet cake (our absolute favorite) and frosted it with this frosting. Despite only having red food coloring, I made only pink rainbow chips(I guess that doesn’t qualify for rainbow!!), but this frosting was a real winner!! We absolutely Loved this!! 

    1. I’m glad you loved the frosting. And the cake, too!!

  3. OMG OMG OMG YES! As a proud petition signer and a shameless pinterest copycat recipe hunter during what I refer to as “the dark days” before they brought rainbow chip frosting back, I cannot explain to you how happy this made me when I opened by email today! I spent basically my whole life eating that stuff straight from the tub as an after school snack and as a temporary escape to heaven, so I was naturally devastated when they discontinued it 😛 Needless to say I’m so excited that you posted this recipe, and I’ll be sure to try it out ASAP. And uhm… rainbow chip worshippers unite? 😀

    1. I’m laughing so hard right now… “the dark days” 🙂 🙂 🙂 Ha!!!

  4. OK, mention of white chocolate, brownies and rainbow chips reminded me to ask you about this: White chocolate brownies. Do they/can they exist? There’s no such thing as unsweetened white cocoa powder, right? (assuming it’s bc white chocolate doesn’t come from cocoa?) But is it possible to make a white chocolate brownie (not blondie) with classic brownie texture/chew? (with, of course, rainbow chips added in) Or did I just eat too many of your bakery peanut butter cookies (with added Snickerdoodle baking chunks, yum) for breakfast and I’m in the throes of delusional sugar-fever??

    1. They do exist. But I’ve never tried them before, so I’m unsure how they compare texture wise to regular brownies– or what their flavor really is like. But I love the idea of white chocolate brownies with rainbow chips inside. So pretty! Search white chocolate brownies on Pinterest or Google and you’ll find something. Then come back and tell me how they are if you try them!

  5. Rainbow chip frosting is the best! I love that you even made the chips yourself!

  6. “If unicorns & leprechauns …” you had me on this line you are so funny baking Goddess 🙂

  7. Kayle (The Cooking Actress) says:

    I AM SO EXCITED RIGHT NOW

    I love that little tub of miracles and haven’t allowed myself to the luxury of it (because ew processed food) in years–BUT NOW I CAN MAKE IT OMGEEE

  8. I am looking forward to making this frosting! And, I have never bought rainbow frosting from the store either. Those store bought frostings are just too sweet for me!

    1. I think you’ll like this one!

  9. Johanna the baker says:

    Oh my gosh thank you I have been looking for a good recipe!!!! Thanks again!!!!!!!!!!!!!!!!!!!!!

  10. Baking Goddess Sally , I want to award your hard work with some muffins . That ‘d be lovely .

  11. Hello Sally! Just wondering but do you use European Butter in any of your baked goods? I was wondering if you’ve noticed a difference in texture and taste? I was thinking of using European Butter for this frosting recipe and maybe for the cake as well!

    1. Not typically– but it’s a wonderful option in both cakes and frostings. Use it!

      1. Can it just be said that you’re a GENIUS!! Just finished my second piece of yellow cake with this amazing rainbow chip frosting! I will even go to the extent of saying I could use a little more frosting??! That normally would never come out of my mouth as I don’t enjoy sweet sweet frosting but this is so beautifully crafted! Yes it is sweet but a good kind of sweet! And the yellow cake!! It’s just the best one I have eaten let alone made! I made this for my husband but I think I’ll be eating more! Thank you for another great recipe! 

        Ps: Could you recreate the Starbucks Birthday Cake Pop?? Pretty please? With pearly white sprinkles on top? 😀

      2. I’m ecstatic that you said you want even MORE frosting on your cake!! I’ve had the pleasure of inhaling 1… or 10… of those starbucks cake pops. They’re certainly amazing! I have a cake pop recipe in my cookbook, Sally’s Candy Addiction, if you have a copy!

    2. I live in Ireland and so always use Kerrygold, I haven’t had any trouble with baking.  Though a few points to note:  the butter takes longer to soften and as it isn’t in stick form, you’ll need to measure out, if you’ve got a scale it’s the most consistent method!

  12. Hi Sally! Do you think this recipe would be enough for your funfetti layer cake or would I need to double the recipe? Thanks!

    1. I don’t think so. I would actually 1.5x it. I fear doubling would be too much, but if you’re OK with frosting leftovers– that’s ok too! I wouldn’t double or 1.5x the white chocolate rainbow chips though. The recipe as written will be plenty.

  13. Diane @ Wine and a Wooden Spoon says:

    When I was young I would search out the half-used can of store bought frosting in my parent’s fridge and sneak spoonful after sweet spoonful until I heard footsteps on the stairs. Then I’d slam the fridge door, toss the spoon and the sink and feign innocence. The frosting mustache gave me away every time 😉 this looks ah-mazing. I can’t wait to eat it straight from the bowl in my own kitchen- no sneaking required. 

  14. I love this idea!

  15. This looks really tasty. Never heard of it before, but I’m in the UK and we don’t have the same stuff as you guys. I’m a bit confused as to what ‘brick cream cheese’ is in the recipe. Doesn’t the fact it’s cream cheese mean it’s not a brick because it’s soft?

    1. Brick cream cheese is just cream cheese sold in a block– not the spread sold in a tub. It’s soft, yes!

    2. Hi Pointy, in Europe it’s usually in rectangular tubs under it’s brand name: Philadelphia soft cheese (the original kind, not the whipped or soft version). Hope this helps. 🙂

      1. Hi. 🙂 I know about Philadelphia, but I wondered what brick soft cheese was. I’m easily confused. 😀

  16. I want to make this for my daughter’s birthday on Saturday. If I make it Wednesday and just keep in the fridge it should be fine right? I just don’t have any other time to make it

    1. Yes, it would be just fine. Keep it covered in the fridge until ready to use. 🙂

  17. It is such a shame that we don’t have block cream cheese here in the UK, only the cheese spread.

    I am sure we are really missing out.

    I am a new baker and I absolutely love your recipes and tutorials.

    Thank you
    Moira

    Hi Sally!
    Since discovering this recipe a couple of months ago
    I have made this too many times to count! I actually bought the canned rainbow chip frosting to compare. Your recipe is leaps and bounds ahead of the canned stuff! As delicious as I remember it tasting as a kid, yours is no comparison! The frosting is so fluffy and has just enough sugar. Melting and coloring the chocolate takes only minutes and it cools while you prepare the frosting. We love this recipe served on top of your yellow sheet cake (made in a 9×13) with sprinkles added to the batter. We have dubbed this recipe as “rainbow cake”. Thank you for making our tongues slap our brains out with this one!

    1. You are right, as much as I adored the can as a kid, I find it much too sweet now! And just seeing those rainbow chips always makes me happy 🙂

  19. Do you think you can put these chips into cake batter? I assume the chocolate would melt, but I feel like the matching cake mix to this frosting doesn’t have just regular sprinkles in it. Maybe I could mix in just a few into the sprinkles  to supplement?

    1. Absolutely! They will slightly melt into the cake batter, I assume, so adding some sprinkles in there as well would help.

  20. Wow! I’m definently going to have to try this! Rainbow chip frosting means as much to me as it does to you. When I was a kid, they had bake sales in school and I ALWAYS got the rainbow chip ones. I love it to this day and sometimes eat it straight out of the tub. As far as the rainbow chips in the frosting, that’s exactly what they are-tiny little chips like chocolate or butterscotch chips, just rainbow ones.

    1. I hope you get a chance to make this and that you love it! 🙂

  21. Do you think this would work okay on a layer cake, or would it be too hard to spread it nicely because of the chips? Also, do you think I’d need to double the recipe if I was making a three-layer cake?

    1. Hi Allix! I would 1.5x the recipe for a 3 layer cake. Shouldn’t be too difficult to spread!

  22. Hello! Do you think the chips would keep if made 2-3 days in advance of making the frosting?

    1. Yes, just keep them in a cool place where they won’t melt 🙂

  23. This recipe is frosting perfection! So fluffy and delicious. The addition of the cream cheese tempers down the sweetness. I used the colored candy melts and they worked just fine. Thanks for this!

    1. You are welcome, Sarah! I’m so happy you enjoyed it!

  24. This frosting was fantastic! I made it with mascarpone instead of cream cheese (I live in the UK where we don’t have brick cream cheese, only the soft spreadable kind which does not hold up well in frosting), and the mascarpone worked perfectly- it had a light, fluffy consistency and holds up very well. The flavour was also fantastic- I definitely plan to make it again. I piped the rainbow chips to make them more chip-shaped which ended up taking a VERY long time- next time I will do it the way you suggest with chopping the chocolate instead, that’s a very clever idea! Thanks for the recipe 🙂

  25. Hi Sally! I adore this recipe but recently mine has been coming out grainy. I always weigh ingredients, made sure butter and cream cheese were room temp, sifted the sugar and followed directions exactly. The sugar just won’t fully dissolve for some reason! The cream cheese was Philadelphia brand. I tried making it three times with different powdered sugars and it didn’t change. Adding a bit of liquid didn’t seem to help either. Any suggestions?

    1. Hi Robin! That’s so odd! I wonder if the powdered sugar is just old? Though you mention you used different bags of it. Perhaps try a new brand? Sifting definitely helps. You can sift a few times for extra insurance, too.

      1. Robin Goodrich says:

        Very odd! It was a brand new bag the first time but I also bought a few different brands to try after noticing the texture. Do you have a favorite brand?

      2. I usually use Domino Sugar brand. 🙂

  26. Hi! I’m wondering what food coloring brand you use? I’m having a hard time achieving bright colors with mine. Thank you!

  27. Ohhhh thank you so much for this! I am a die hard rainbow chip lover. I am from Canada, and as far as I know, I think it is still discontinued, I’d have to check my sources. However when we make it to the states, that is my first stop…. icing, pop tarts (yous guys south of the border have way more flavours) and yogurt (same reason). However my childhood memories were rainbow bit cake with rainbow chip icing. Matchy matchy! I’m not a cake lover, but when that was pulled out with candles a blazin’ I was in birthday heaven. I was so disappointed when it was taken off the shelves and on top of it they tried to replace it with a knockoff sprinkles version. Blugh! You’re absolutely right it’s all in the consistency of the creamy chocolate chip. Cant wait to try this.

  28. Hi Sally! Love your recipes. Do you think this frosting could be made using your Swiss meringue buttercream as the base and adding the chips? My family is obsessed with your SMBC and always wants it for birthdays. Thanks!

    1. Absolutely! Swiss meringue buttercream with these fun chips would be delicious. Fold them in after the buttercream is finished (after you add the vanilla).
