Loaded Sugar Cookie Bars

To me, baking something quick means BARS. Brownies, blondies, rice krispie treats, you name it. Depending on the recipe, some bars are made in under 30 minutes with with no mixer required. And you usually don’t need to chill the dough or batter, either.

I love making these cookie bars because not only are they completely over-the-top delicious, but they save me SO much time in the kitchen because they start with a pre-made sugar cookie mix! To the mix, you may add whatever goodies your little heart desires. I usually use whatever extras I have laying around. Today I used mini peanut butter cups, peanut butter M&Ms, and chocolate chips.

For a homemade version, use my sugar cookie bars recipe and leave out the sprinkles. Add whatever add-ins you’d like.

These cookie bars bake up pretty quickly, so be sure to watch them right around the 20 minute mark. At exactly 25 minutes, they were done. They were lightly browned on top and pulling away from the edges on the sides. They have the tendency to get too brown and almost burn, so watch them CLOSELY while they bake.

Description

Soft sugar cookie bars loaded with chunks of colorful chocolate and your favorite candy add-ins. Use a store-bought cookie mix or see my recipe notes for the homemade version.


Ingredients

  • 1 package prepared dry sugar cookie mix (plus ingredients called for on the back of the package – for the Pillsbury mix I used, I had to add 1 stick butter + 1 egg) OR use 1 package pre-made refrigerated sugar cookie mix
  • 1 cup peanut butter M&Ms
  • 1/2 cup chocolate chips
  • 1/2 cup mini peanut butter cups (OR 1/2 cup chopped Reese’s Peanut Butter Cups)

Instructions

  1. Preheat oven to 350Ā°F (177Ā°C). Spray an 8-inch or 9-inch square baking pan with nonstick spray or line with parchment paper. Set aside.
  2. In a large bowl, thoroughly mix together the called-for ingredients on the sugar cookie mix to make the dough. Once dough is prepared, mix in all of your mix-ins. Dough will be very thick.
  3. Press dough evenly into the prepared baking dish. Press any extra add-ins into the top of the bars.
  4. Bake for 25 minutes or until edges are lightly browned. For neat, clean cuts, cool completely before cutting into squares.

Notes

  1. Add-Ins: Feel free to use any add-ins you have on hand. Try white chocolate chips, butterscotch chips, nuts, chopped candy bars, sprinkles, Reese’s Pieces, etc.
  2. Homemade Version: Instead of pre-made mix, you can use the dough from my homemade sugar cookie bars instead. Leave out the sprinkles, if desired, and add your favorite add-ins as called for in this recipe. Bake for 25-26 minutes or until the edges are lightly browned.

  1. Gorgeous and awesome. Bars are so easy and versatile–one of the reasons why I’m OBSESSED with making them šŸ™‚ throw whatever you’ve got on hand and cut those suckers up and you have dessert in no time. I’m sure your friends were beyond impressed and delighted when these showed up to the party with you. I would be (and would promptly hoard the pan and lock myself in a back bedroom).

    My 14 year old daughter was bored so I asked if she wanted to bake something. She said sure, that sounds like fun.

    I pulled up your blog and told her to pick anything she wanted and she could make it. There were several contenders!

    In the end, these sugar cookie bars won! (So easy to make, perfect for a 14 year old!) She ended up using peanut M & M’s and pretzel M & M’s because peanut butter M&M’s no longer exist?!?!

    They were a huge hit with the kids! I think they ate half the pan as soon as they were cool enough.

    1. I’m glad you chose my site to bake from, Anna! I love your daughter’s choice of add-ins. Peanut Butter M&Ms no longer exist?!?!??! Where have I been? That’s a huge disappointment! I loved those. Anyway, I’m glad these were a hit!

        Hi again!

        My daughter wanted to bring a snack to school and since this recipe was so easy, she wanted to make another batch. This time, she chose peanut butter cookie dough, mini Reese’s Pieces, peanut butter chips, chocolate chips and Heath bar crushed up.

        I love this recipe, it’s easy enough for her to make on her own and the combinations are endless!

        Thanks Sally šŸ™‚

        PS~Happy Birthday!!

  3. OMG I made these for my boyfriend and sent some to my brother in college….they are both sugar freaks! They LOVED it! I put peanut butter m&ms, mini chocolate chips, and chopped walnuts…delicious! I think I’m going to try some dark chocolate m&ms instead of peanut butter ones next time šŸ™‚ Great recipe!

    1. Hey Heather! SO glad you made these. And they are the perfect recipe to send to loved ones because they package so nicely. Dark chocolate M&Ms would be SO good.

  4. These sound wonderful, so happy that I came across them while looking over your site. Just a question, how long do they stay fresh covered at room temperature? Thanks so much!

    1. Hey Jen! About 1 week. But they won’t last that long!

  5. Just made these for a Super Bowl party, I pulled out just the blue and orange peanut butter m&m’s and called them Bronco Bars, so yummy, everyone loved them! I baked them for a few minutes over the called for 25 minutes and they were perfectly gooey yet fully cooked. Thanks for the idea and recipe šŸ™‚

  6. Just wondering if the fudge ripple
    Monster bars freeze well? This was the closest recipe I could find to them on the site hahaha

  7. Hey Sally! These look so easy to make, and are so colorful! I’ll be making them for a potluck tomorrow. If I wanted to make it again, without the premade mix, could I use your sugar cookie bar base? (Like the one for the Frosted Sugar Cookie bars) or would it not be able to handle the add-ins? Or do you have a different recommendation? Just for those days when I have a bit more time. šŸ™‚

    1. Hi Lydia! Yep, you can use my from-scratch sugar cookie bar base instead.
