Chocolate and peanut butter are two of my favorite flavor combinations. If you love buckeye balls like me, you’re going to love these buckeye brownies!

If you’ve never had a buckeye before, it’s basically a peanut butter truffle that’s partially dipped in chocolate. They are rich and creamy, with delicious peanut butter flavor.

And because I love them so much, I decided to make these buckeye brownies and they did not disappoint! Don’t get me wrong – all brownies are delicious, but these are something to talk about.

They contain 3 delicious layers: a brownie layer, a peanut butter layer and a chocolate ganache layer. Plus I used box brownie mix to make the recipe even easier. These brownies will win anyone over!

How to make buckeye brownies

Step 1: Make the box mix brownies (layer 1)

To start, line a 9×13″ baking pan with foil and lightly grease with non-stick spray. Don’t skip this part – you don’t want your brownies to stick!

The combine brownie mix with ingredients listed on package and stir until smooth. Pour into pan and bake at 350°F according to directions on box. Then remove from oven and let cool completely.

Step 2: Make peanut butter mixture (layer 2)

In a large bowl, mix together the butter, peanut butter and vanilla. Next add in brown sugar. Then slowly beat in powdered sugar. If the mixture gets too thick, you can add a splash of milk to thin it out a little.

Then spread the mixture on top of the boxed brownie layer. I like to use a spatula so the layer is even and smooth.

Step 3: Top with chocolate ganache (layer 3)

Melt the chocolate chips and butter in a small bowl in the microwave. Cook at 50% power for about 1-2 minutes, or until melted. Stir the melted chocolate, then pour over the peanut butter layer.

Spread the chocolate glaze with a spatula to smooth out the surface. Refrigerate the brownies for 30 minutes, or until the top chocolate layer sets.

These buckeye brownies are seriously to die for! Grab a big glass of cold milk and dig in.
