Important Recipe Notes
- Cool the cupcakes completely before adding the buttercream. Warm cupcakes can melt the frosting and make it difficult to pipe.
- Use room-temperature ingredients for the cupcake batter, especially the egg and yogurt, to help everything mix evenly.
- Do not overmix the batter. Mix just until the dry ingredients are incorporated to keep the cupcakes soft and tender.
- Use very soft butter for the buttercream so it becomes smooth and fluffy when beaten.
- Adjust the powdered sugar as needed. Start with 1½ cups and add more if the frosting needs to be thicker for piping.
- For smoother frosting, blend the blackberries first and strain out the seeds before mixing them into the buttercream.
- Fresh blackberries work best for the buttercream, but make sure they are not overly wet. Pat them dry before using.
- Store frosted cupcakes in the refrigerator in an airtight container and let them sit at room temperature for a few minutes before serving.
