- Gluten-free Flour Blend: I tested this recipe with King Arthur Measure for Measure and Cup4Cup Multipurpose blend. Both worked great and I am confident other 1:1 blends for gluten-free baking will work as well, as long as it contains Xanthan Gum or another binder.
- Dairy-Free: I am confident you could replace the butter with Earth Balance Vegan Buttery Sticks to make these dairy-free. Also be sure to swap your chocolate chips, chocolate candies, and peanut butter cups for dairy-free alternatives as well.
- Eggs: Be sure to use one whole egg and one egg yolk as the recipe indicates. The extra yolk is needed for the chewy texture of these bars and makes them less crumbly.
- Chocolate Chips: I used semi-sweet chocolate chips but you can use milk or dark chocolate if that is what you prefer.
- M&M's: are not specifically labeled gluten-free but do not contain gluten-ingredients and are generally considered safe to eat.
- Peanut butter cups: I used miniature Reese's peanut butter cups, check the back of the bag for a gluten-free label as Hershey's will label verified products.
Instructions
- Cream together butter and sugars until light and fluffy.
- Add in egg, egg yolk, and vanilla extract. Blend again until light and fluffy.
- Whisk the flour, baking soda, and salt together, then add to the creamed mixture.
- Blend until well combined.
- Add in chocolate chips, M&M's, and peanut butter cups.
- Stir to combine with a spoon, breaking up peanut butter cups.
- Spread into a 9-inch square pan that has been lined with parchment paper.
- Press extra chocolate chips, M&M's, and peanut butter cups on top.
- Bake!
Storage
These bars are best eaten fresh while still warm and gooey! They will keep well for several days though, in an airtight container or wrapped tightly, and left at room temperature.
These bars also hold up well for freezing. Just slice them and place in an airtight container. It helps to keep them tightly wrapped and remove any excess air. They will last for 3 months or so in the freezer. Thaw at room temperature.
Top Tips
- Press extra chocolate chips, M&M's, and peanut butter cups into the top of the bars before baking! This is what gives them their show stopping appearance and you can see exactly what's inside!
- Measure the flour using the spoon and level technique. This is where you fluff up our flour, spoon it gently into the measuring cup, and then level off the top with a straight edged knife or spatula.

I made this for Superbowl Sunday and it was a total hit. It was the only dessert with no leftovers. Even my brother who refuses to eat anything gluten free had one. After they were gone, I told everyone they were gluten free and they were shocked. Definitely a fantastic recipe and so easy to make.
