Easy peanut butter brownies
The best part about the brownies is how easy they are to customize.
In fact, you can use pretty much any brownie recipe you want for the base, as long as the recipe you choose fits a standard eight inch baking pan.
For the pb brownies in the photos, I made everything from scratch. But feel free to go with a box brownie mix if you are low on cocoa powder or are running short on time and need to quickly whip up an impressive fancy dessert.

Ingredients for the recipe
To make the brownies, you will need peanut butter or a nut free substitute, powdered sweetener, butter or plant based butter, optional oil and chocolate chips, and the ingredients for your favorite brownies.
Both natural peanut butter or conventional brands like Skippy or Jif work well. Or change the flavor by substituting almond butter, cashew butter, or coconut butter.
The chocolate ganache topping can be left off completely if you wish. Or if you want an oil free chocolate ganache, feel free to simply skip the oil. The chocolate sauce still tastes delicious. It just won’t be as smooth or easily spreadable.

Peanut butter frosting
For the three ingredient peanut butter filling, cream together six tablespoons each of peanut butter and regular butter with one and a half cups of powdered sugar or powdered erythritol for sugar free brownies.
For vegan peanut butter brownies, it is fine to use a vegan butter spread and this recipe for Vegan Brownies as the chocolate brownie base.
If the peanut butter frosting is too thick, add a half tablespoon milk of choice.
The frosting recipe makes enough to cover one batch of brownies. If you want to make extra, store leftover frosting in a covered container in the refrigerator for up to a week.

Basic cheesecake frosting
Prefer a cream cheese frosting instead of a buttercream?
Simply whip up eight ounces of softened cream cheese with half a cup of peanut butter, a pinch of salt, one cup of powdered sugar, and one and a half teaspoons of pure vanilla extract.
You can use this instead of the buttercream frosting above if you wish. The recipe was adapted from both my Peanut Butter Dip and Chocolate Cream Cheese Frosting.

How to make peanut butter brownies
Start by preparing and baking your chocolate brownie base. This can be done the day before to save time if you wish.
Blend the peanut butter frosting ingredients in a stand mixer or with hand beaters until completely smooth. Spread this peanut butter filling over the brownies.
If desired, melt three ounces of chocolate chips or broken up chocolate bars with half a teaspoon of vegetable or coconut oil.
Swirl or smooth this over the frosted brownies, then chill in the fridge or freezer for a few minutes until the chocolate hardens.
The resulting tasty brownie treat is chewy, soft, dense, fudgy, and packed with rich chocolate peanut butter flavor!

I plan to make a 9×13 pan of brownies. Can you provide ingredient amounts for the peanut butter filling to cover a 9×13 size? Thanks!

Leslie says
Making them now. How to you cut them so perfectly with the hardened chocolate on top? I made them before and they were delicious but didn’t look half as pretty as yours! What is your secret to cutting them ?
Tammy Thompson says
Cool at room temp. Once all is set, use serrated knife in a slow sawing motion. Enjoy
Lynn says
Do you have to cool brownies before adding the peanut butter mixture? Also, can I refrigerate instead of freezing after adding the chocolate layer?
