Tips & Variations
Double-Chocolate Buckeyes: Fold ½ cup mini chocolate chips into the dough for extra melty pockets in every bite.
Storage: Store your Buckeye brownie cookies in an airtight container at room temperature for up to 3 days, or refrigerate for up to 7 days. Layer with parchment paper to keep the peanut butter filling and ganache from sticking.
