Buckeye Cupcakes with Chocolate Peanut Butter Ganache, Gluten Free

Buckeye Cupcakes with Chocolate Peanut Butter Ganache, gluten-free. Happy Valentine's Day.

Buckeye filling turns a plain yellow cupcake into a little bit of a buckeye candy bar cake. Top it with chocolate peanut butter ganache and the whole thing is like a delicious indulgent treat.

Hello, Valentine’s Day.

Plan ahead and make the buckeye filling so it can develop that great flavor, but it can sit around in the freezer waiting until you feel like baking cupcakes. Then it goes together quickly. There will be plenty of buckeye filling leftover for another use and it keeps for weeks. Be sure to measure out 200 grams or 3/4 cup and freeze that separately for easy mixing into the cupcake batter later on.

The ganache is a simple and quick. Top the cupcake with a chocolate peanut butter candy heart and it’s a total peanut butter sweet-heart theme thing. Use some festive red (greaseproof) cupcake liners unlike mine which are supposed to be red but look a tiny bit orange after baking. Sigh.

Welcome to the corner of Chocolate and Valentine which is just around the corner from Peanut and Butter, she says after one too many cupcakes. I’m going back into the kitchen now and I promise to lay off the coffee. And the cupcakes.

Buckeye Cupcakes. Covered in Chocolate Peanut Butter Ganache. Want one?

Buckeye Cupcakes with Chocolate Peanut Butter Ganache
Buckeye cupcakes are all things peanut butter. Covered in a chocolate peanut butter ganache, these will satisfy anyone who loves both flavors together. The buckeye mixture can be made well ahead of time and stored in the freezer. Thaw the amount you need for the cupcakes ahead of time so it mixes easily into the batter - leave the thawed buckeye dough at room temperature for at least 30 minutes for best results.
