How to make Buckeye Brownies (Overview)
Making Buckeye Brownies is a breeze. Start by melting the butter and bittersweet chocolate together in a pan—this creates your rich base. Stir in some sugar and eggs; you’re on your way to dessert bliss! After folding in flour, divide the batter and create that dreamy peanut butter layer in the middle. Don’t forget the semi-sweet chocolate topping to seal the deal. Pro tip: Let these babies cool completely before slicing—otherwise, you’ll end up with a gooey mess (though that sounds tempting!).
How to serve Buckeye Brownies

- Top with a drizzle of caramel for an extra layer of flavor.
- Serve warm with a scoop of vanilla ice cream that melts into the chocolate goodness. Heavenly!
- Arrange them on a colorful plate to make an enticing dessert display at your next gathering.

How to store Buckeye Brownies
These brownies keep well! Store them in an airtight container at room temperature for up to 5 days, or in the fridge for up to a week. If you’ve made a big batch, you can also freeze them for up to 3 months. Just layer them with parchment paper in an airtight container to prevent sticking. When you’re ready to enjoy, let them come to room temperature or pop them in the microwave for a few seconds to get that gooey texture back.
Tips to make Buckeye Brownies
Here are some insider tips:
- Use room-temperature eggs: They incorporate better into the batter and create a smoother mix.
