The contrast of colors and textures, along with that heavenly aroma, will make any dessert table shine bright! 🍦✨

How to Store Oreo Reese’s Fudge Brownies

Want to keep that fudginess intact? Store leftovers (if there are any!) in an airtight container in the fridge for up to 5 days.

Tips to Make Oreo Reese’s Fudge Brownies

  • Don’t Be Shy with the Mixing: Beat those eggs and sugar well for a fluffy brownie texture!
  • Chill the Peanut Butter: A chilled peanut butter mixture makes it easier to spoon over your brownie layer.
  • Use High-Quality Cocoa: It’s worth it — better cocoa means better flavor.
  • Add More Crunch: If you want extra texture, throw in chopped nuts or more Oreo cookies.

Variation

Feeling adventurous? You could easily swap out peanut butter for almond butter or use different candies like Snickers instead of Reese’s. Want to make it vegan? Substitute the eggs with flaxseed meal and use a dairy-free butter — still delicious, I promise!
