These Peanut Butter Brownies are just as amazing as they look. I like to make them 1 day in advance because I think they taste even better after the brownies have had time to cool in the fridge. You just can’t beat the peanut butter/chocolate combo!

How to make Peanut Butter Brownies:

Make the Brownies:

In a mixing bowl add granulated and brown sugars and melted butter. Beat until well combined. Add eggs and egg yolk, beating after each addition. Add milk and vanilla extract.

In a separate bowl mix together the flour, cocoa powder, baking powder, and salt.
Add dry ingredients to wet ingredients and mix just until combined. The batter will be thick.
Pour batter into a greased 9×13” baking pan and spread into an even layer. Bake at 350 degrees for 35-45 minutes or until a toothpick inserted in the center comes out clean.

While brownies cool, make the Peanut Butter Frosting:

Beat together butter, and peanut butter until smooth. Add powdered sugar and vanilla and beat again until smooth. Add a little splash of milk, beating well until light and fluffy. Add more milk or powdered sugar if needed to make the frosting thicker or thinner.
Smooth frosting over the top of cooled brownies. Refrigerate while you make the chocolate topping.

Make the Chocolate Glaze: Place chocolate chips and butter in a microwave safe bowl. Microwave in 30 second intervals, stirring in between, until just melted and smooth. Allow to cool for 3-4 minutes. Spread evenly over the frosted brownies. Add chopped Reese’s chocolate to the top. Return to fridge to allow the chocolate to set. Cut into squares and serve!

    Hi there

    I don’t suppose you have the recipe conversion in grams (sorry UK) I have checked the conversion rate on a few different websites and they all give variation!

    Thanks

    Made these twice now to rave reviews and recipe requests. They. Are. Amazing!
    If you are looking for a recipe that is delicious and will wow your guest, this is it.
    Today I was in a really big hurry so I’ll be honest I used a boxed brownie mix with the peanut butter topping and chocolate glaze as noted in this recipe and it was a huge hit. Just be sure to get a really good brownie mix that’s chocolatey and fudgy
