This is the secret to making ordinary cupcakes extraordinary. Don't worry, it's really very easy!
1. Once cupcake is cool, insert an apple corer into the center of cupcake, about 1 inch deep.
2. Remove cored cake from center of cupcake. If the center doesn't remove with corer, use a spoon to get the cored cake out.
3. Once cake center is removed, fill a pastry bag or plastic bag (with one lower corner removed) with filling. This can be done with or without a decorating tip.
4. Fill center of cupcake with filling until it is heaping out of the cupcake. Now the cupcake is ready to be frosted.
