- Divide the cake batter between the muffin tins, filling each one with about ¼ cup of batter.

- Bake for 15-17 minutes, or until a toothpick inserted into the center comes out clean.
- Remove the cupcakes to a wire rack and cool completely before frosting.

NOTES
- Make sure to spoon and level your ingredients into the measuring cup for the most accurate results.
- Generously spray your cupcake tin or line it with paper liners for easy release.
- Don’t overmix the cupcake batter, or you could end up with dry, dense cupcakes. Only mix until there are no lumps in the batter.
- Don’t overfill the wells of the cupcake tin or you will end up with “muffin tops” on your cupcakes, and they will be more difficult to frost.
- Allow the cupcakes to cool completely before frosting; otherwise, the frosting will melt off.
Storage: Store blackberry cupcakes in an airtight container in the refrigerator for up to 2 days. Freeze cupcakes and buttercream separately for up to 3 months.
