Tips for Successful Buckeye Brownies
- The Brownie Base is Key: Let the brownies cool completely before adding the peanut butter layer. If they are even slightly warm, the peanut butter mixture will melt and become greasy, and the layers will muddy together.
- Peanut Butter Perfection: Use a standard, no-stir creamy peanut butter like Jif or Skippy for the filling. Natural peanut butters (with oil separation) can make the filling too runny or grainy.
- Butter Temperature is Crucial: For the peanut butter layer, ensure your butter is softened (left at room temp for 30-60 mins), not melted. Soft butter creams beautifully with the peanut butter and sugar to create a smooth, spreadable filling.
- Master the Ganache: When heating the cream for the ganache, watch it closely. It should be just simmering with small bubbles around the edges—do not let it boil vigorously. Pouring hot cream over the chocolate chips and letting them sit for a few minutes before stirring is the secret to a glossy, lump-free ganache.
- Clean Cuts for Beautiful Bars: For picture-perfect squares, use a sharp knife dipped in hot water and wiped clean between each cut. Chilling the brownies thoroughly (at least 1 hour, or even overnight) makes slicing much easier and gives you clean, defined layers.
Frequently Asked Questions (FAQ)
Q: Can I use a homemade brownie recipe instead of a mix?
A: Absolutely! Use your favorite 9×13-inch pan homemade fudge brownie recipe. Just ensure it’s completely cooled before proceeding.
Q: How should I store these brownies, and how long do they last?
A: Store them in an airtight container in the refrigerator for up to 5 days. The chilled texture is fantastic! They can also be frozen for up to 3 months. Thaw overnight in the fridge before serving.
Q: My peanut butter layer seems too thick to spread. What can I do?
A: This is what the milk is for! Add the third tablespoon of milk, one teaspoon at a time, until the mixture reaches a smooth, spreadable consistency similar to thick frosting.
Q: Can I use milk chocolate chips for the ganache?
A: Yes, you can. Semi-sweet chocolate provides a classic, balanced sweetness that contrasts nicely with the sweet peanut butter. Milk chocolate will make the overall dessert sweeter, while dark chocolate will offer a more intense, less sweet finish.
Q: Why are they called “Buckeye” Brownies?
A: They are named after the Buckeye candy, a regional treat from Ohio (the Buckeye State). The candy is a ball of sweet peanut butter filling partially dipped in chocolate, resembling the nut of the buckeye tree. These brownies replicate those iconic flavors in bar form.

Ingredients
For the Brownie Base:
- 1 box (approx. 18-20 oz) family-style fudge brownie mix
- The eggs, oil, and water as specified on the box
For the Peanut Butter Layer:
- ¾ cup creamy peanut butter
- ½ cup (1 stick / 113g) unsalted butter, softened
- 2 cups powdered sugar
- 1 teaspoon pure vanilla extract
- 2–3 tablespoons milk
For the Chocolate Ganache:
- 1 cup semi-sweet chocolate chips
- ½ cup heavy cream
Directions
- Bake & Cool the Brownies:
- Preheat your oven and prepare the brownie batter exactly as directed on the box for a 9×13-inch pan.
- Bake according to package instructions until a toothpick inserted comes out with moist crumbs (not wet batter). Allow the brownies to cool completely in the pan on a wire rack. This is a critical step.
- Make the Peanut Butter Layer:
- In a large mixing bowl using a hand mixer or stand mixer, beat the softened butter and creamy peanut butter together until smooth and combined.
- Add the powdered sugar and vanilla extract. Beat on low speed until the sugar is incorporated, then increase speed to medium and beat until combined. The mixture will be thick.
- Add 2 tablespoons of milk and beat until smooth and spreadable. If the mixture is still too thick, add the remaining milk, one teaspoon at a time, until you reach a smooth, frosting-like consistency.
- Spread this peanut butter mixture evenly over the completely cooled brownie layer. Place the pan in the refrigerator to chill while you make the ganache.
- Make the Chocolate Ganache:
- Place the semi-sweet chocolate chips in a medium heatproof bowl.
- In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer (small bubbles will appear around the edges). Do not let it boil.
- Immediately pour the hot cream over the chocolate chips. Let it stand, untouched, for 2-3 minutes to allow the chocolate to melt.
- Gently whisk the mixture from the center outwards until it is completely smooth, glossy, and uniform in color.
- Assemble & Chill:
- Remove the pan from the refrigerator. Pour the warm ganache over the peanut butter layer.
- Use an offset spatula or the back of a spoon to gently spread the ganache into a smooth, even layer that covers the entire surface.
- Return the pan to the refrigerator and chill for at least 1 hour, or until the ganache is fully set.
- Slice & Serve:
- For the cleanest cuts, use a sharp knife dipped in hot water and wiped dry. Slice into 16 squares (or your desired size).
- Serve slightly chilled. Store any leftovers in an airtight container in the refrigerator.
