The three layers in these peanut butter truffle brownies are easy to make and only require a few simple ingredients.
- Brownies - You will need one box brownie mix or a double batch of these chocolate chip brownies. If you are using the box mix, you will also need the ingredients from the back of the box.

- Peanut Butter - The filling is best when made with a creamy peanut butter like Jif.
- Marshmallow Fluff - Adds a soft fluffy texture to the filling.
- Vanilla Extract & Salt - Adds a good balance of flavor.
- Heavy Cream - Used to make a creamy ganache topping.
- Chocolate Chips - Use your favorite type of chocolate for this layer. Milk chocolate chips, semisweet chocolate, or dark chocolate chips are all good choices.
How to make Buckeye Brownies
These chocolate peanut butter brownies come together so quickly because they start with a box mix. Once they are cool, add the toppings and devour!
- Bake the brownies. Mix together the brownie mix and ingredients from the back of the box. Spread the brownie batter in a 9x13 pan and bake. Cool to room temperature.
- Make the peanut butter truffle filling. Beat the softened butter, peanut butter, marshmallow cream, vanilla, and salt until smooth and creamy. Add the powdered sugar and heavy cream until the filling is slightly spreadable.
- Assemble brownies. Spread the peanut butter filling evenly over the cooled brownie layer. You may need to use your finger tips to help press it into place.
- Make the chocolate ganache. Place the heavy whipping cream and chocolate chips in a microwave safe bowl for 30 seconds. Stir until melted and creamy. Pour the chocolate on top of the filling and use a spatula to spread it out evenly.
- To Store - Keep the brownies with peanut butter in a covered container on the counter for 2-3 days. You can also keep the brownies longer by covering the pan tightly and refrigerating for 5-7 days.
- To Freeze - Cut the frosted brownies into squares. Place on a sheet pan and freeze for 1 hour. Then wrap each brownie in two layers of plastic wrap. Place in a freezer safe bag or container and freeze for up to 2 months.
- To Serve - Thaw the brownies overnight in the refrigerator before serving.
Tips and Tricks
- Line the baking pan with parchment paper or foil. This will help you lift the brownies out easily after they are frosted.
- A natural peanut butter is not recommended for the truffle filling.
- Try different chocolate chips based on your chocolate preference. Milk chocolate will be very sweet, so we usually use semisweet or dark chocolate.
- Cut the brownies with a plastic knife to avoid having the brownies stick to the knife.
What are buckeyes?
Buckeyes are a popular Ohio candy. The candies feature a soft peanut butter filling that is dipped in a chocolate coating. This peanut butter brownie recipe is much easier and faster than dipping individual candies.
Can you use a chunky peanut butter for the filling?
You sure can. The crunchy peanut butter will add a good crunch to the peanut butter mixture.
Can you freeze chocolate peanut butter brownies?
Yes you can. Wrap individual brownies in plastic wrap and then place in a freezer safe container and freeze for up to 2 months.
