Homemade Funfetti Cupcakes with Milk Chocolate Frosting

aka BIRTHDAY cupcakes! 😉

With my new hot pink apron tied tight (thanks for the birthday present Kristen!!), I stood in my (tiny) kitchen staring into my pantry. What on earth should a food blogger/baker make for her own birthday?!

In the past few weeks I’ve celebrated with friends by making a lot of different treats, but I think it’s time for an all star classic FUNFETTI cupcake.  Fluffy, buttery cake studded with bright sprinkles and adorned with creamy, dreamy milk chocolate buttercream frosting and more sprinkles.  I die. Nothing says a birthday like good ‘ole funfetti, am I right?!

These homemade cupcakes taste just like your classic boxed yellow cake mix. They are moist, fluffy, and full of rich buttery flavor thanks to the use of melted butter in the recipe.  The milk chocolate buttercream is another classic recipe.  It is so luscious and creamy. Buttery almost, too.  I can see myself frosting anything and everything with it… cookies, brownies, cakes, etc. It is literally perfect.

And on top of the creamy milk chocolate buttercream, I threw a ton of different sprinkles because let’s face it… I’m a tad obsessed.  Who doesn’t love sprinkles?! If you don’t, you are clearly lost on Sally’s Baking Addiction. 😛

And look! Aren’t these edible gold glitter stars SO super cute?! I found them at Michael’s and went nuts. I got a little heavy handed with the glitter stars on my first one… ooops!

Sprinkle mess or not, I am in LOVE with these cupcakes & frosting.  They were the perfect ultimate birthday treat and I can see myself using this classic yellow cupcake recipe & the frosting recipe time and time again. A win-win in my book!

Homemade Funfetti Cupcakes with Milk Chocolate Frosting


Homemade Funfetti Cupcakes 

  • 1 and 1/2 cups all-purpose flour
  • 1 and 1/2 tsp baking powder
  • 1/4 tsp salt
  • 2 large eggs
  • 2/3 cup sugar
  • 3/4 cup (1.5 sticks) unsalted butter, melted
  • 2 tsp vanilla extract
  • 1/2 cup milk
  • 1/2 cup sprinkles

Milk Chocolate Buttercream Frosting

  • 1 cup (2 sticks) unsalted butter, softened
  • 3 and 1/2 cups powdered sugar
  • 1/2 cup cocoa powder
  • 1/2 tsp salt
  • 2 tsp vanilla extract
  • 3 Tbsp half + half or milk or heavy cream (I used fat free half + half)


For the cupcakes: Preheat the oven to 350F. Line the muffin tin with cupcake liners. Set aside.

Whisk the flour, baking powder, and salt together in a medium bowl. Set aside. In another medium bowl, beat the eggs and sugar with a stand mixer (with paddle attachment) or electric handheld mixer until light and foamy, about 2 minutes. While beating, slowly pour in the butter and then the vanilla.  While mixing, add half the dry ingredients, then add all the milk, and follow with the rest of the dry ingredients. Do NOT overmix the batter. Gently fold in 1/2 cup sprinkles.

Divide the batter evenly in the prepared cupcake liners. Bake for about 20-25 minutes until a toothpick inserted in the middle comes out clearn. Allow cupcakes to cool completely before frosting.

For the frosting:  Sift 3 cups powdered sugar & cocoa powder into a medium bowl.  Set aside.

On medium speed, cream butter for a few minutes in a stand mixer with the paddle attachment. Turn speed to LOW and slowly pour in the dry ingredients.  Be careful so that the dry ingredients do not blow everywhere!  Mix until sugar/cocoa are absorbed by the butter.

Turn up mixer to medium speed and add the vanilla and salt.  Slowly add in the half + half (or milk or cream) and beat for about 2 minutes or until the frosting reaches a desired thickness. Add the last 1/2 cup of powdered sugar if needed to increase frosting thickness (I did not need it).

Pipe or spread the frosting onto the cooled cupcakes. Decorate with additional sprinkles, if desired.

  1. We just made these funfetti cupcakes with your vanilla buttercream for one of my twins’ birthday parties last week and they were delicious!!! The funfetti was adorable! They were delicious and perhaps a little dense/dry-ish. Not exactly dry tho, but not super moist..but still very good. The flavor was amazing though. Then, this week for the other twin’s party we made your vanilla cupcake with this chocolate frosting and OMG…BEYOND DELICIOUS! The chocolate frosting is insane it’s so good and the cupcakes were much more light and airy than the funfetti…not sure why. At any rate, both are keepers in my book! Thank  you! 

  2. does the milk chocolate frosting need to be refrigerated?

  3. Hi, I have a hand held mixer, but I do not have a paddle attachment, I only have a whisking attachment and a dough attachment. Can I use one of them to make the frosting? If not, how do I make the frosting by hand? I actually want to make the triple chocolate layer cake frosting, but I wasn’t able to post a comment on that page.

    Thank you,
    Kay 🙂

  4. Um hi… I made the funfetti batter. Not quite sure what went wrong … but it was like pancakes..  but more bread consistency? .-. I’m assuming it was too much baking powder. Is it supposed to be 1 1/2 tsp? 
    I also substituted butter with applesauce… maybe that was the bad idea?
