The perfect brownies for peanut butter lovers! Peanut Butter Cup Brownies are rich, fudgy, and full of peanut butter cups and peanut butter chips.
Peanut butter and chocolate is one of my favorite flavor combinations. (Isn’t it everyone’s really?!) I love peanut butter chocolate cookies, peanut butter chocolate cupcakes, and I especially love these brownies.
Brownies are probably my favorite dessert to make because, not only are they so delicious, but they are quicker and easier than most desserts and require less dishes. Just one bowl for the batter and one pan for the brownies!
These are especially delicious because they are super rich and fudge brownies and are full of peanut butter chips and mini peanut butter cups.
Why You’re Going To Love This Recipe
- If you are a peanut butter lover like me, these are going to be your new favorite! I love a brownie with different mix-ins so I love that these have 2 different textured mix-ins but they’re both peanut butter!
- Brownies are a really quick and easy dessert! The batter only takes about 10 minutes to whip up (and you only need one bowl!) and then they bake for less than 30 minutes. So if you need a last minute dessert, these are perfect.
Ingredients
- Unsalted butter – if you use salted, just leave the salt out of the recipe.
- Unsweetened cocoa powder
- Granulated sugar
- Eggs
- Vanilla
- Salt
- Flour
- Baking powder
- Mini peanut butter cups – these are going to be in the candy aisle. Reese’s makes them and they come already unwrapped. You can also order them online.
- Peanut butter chips – you can find these with the chocolate chips in any large grocery store or you can order them online.
How To Make Peanut Butter Cup Brownies
- Prepare. Lightly grease the bottom of a baking pan and line it with parchment paper.
- Melt butter. In a microwave safe bowl, melt the butter. Allow it to cool slightly.
- Add ingredients. Whisk in the cocoa powder and sugar. Beat in the eggs, vanilla extract, and salt just until the eggs have been fully incorporated into the batter.
- Add dry ingredients. Gradually mix in the flour and baking powder until well combined.
- Add mix-ins. Fold in half the amount of mini peanut butter cups and peanut butter chips. Set the remaining aside for topping.
- Transfer. Spread the brownie batter into the prepared baking pan in an even layer.
- Top. Add the remaining Reese’s peanut butter cup minis and chips for topping.
- Bake. Bake at 350 F for 23-27 minutes.
- Cool. Let it cool on a wire rack on the counter completely before cutting into squares and serving. Enjoy!
How Long Are They Good For?
These brownies will be fine at room temperature in an airtight container for up to 3 days. You can store them in the fridge for up to 5 days.
Can You Freeze Them?
You can freeze leftover brownies for up to 3 months. I like to wrap them individually in plastic wrap and then place in a freezer ziploc bag.
When you are ready to enjoy one, just let it sit at room temperature until it reaches your desired temeprature.
