Recipe Notes
- Make Ahead & Freezing Instructions: Cupcakes can be made ahead 1 day in advance, covered, and stored at room temperature. Frosting can also be made 1 day in advance, covered, and stored in the refrigerator until ready to use. Decorate/assemble cupcakes immediately before serving. Leftover cupcakes keep well covered tightly at room temperature or in the refrigerator for 3 days. Frosted or unfrosted cupcakes can be frozen up to 2 to 3 months. Thaw overnight in the refrigerator.
- Boxed Mix: Use boxed brownie mix as a shortcut, but don’t forget to adjust the frosting accordingly since the peanut butter frosting recipe below only makes enough for 10-12 cupcakes.
