- Frost the cake with your choice of frosting. Sprinkle chopped peanut butter cups over the top of the frosting if desired.
Baking Tips:
Add flavor to canned icing :
If you’re starting with plain or vanilla frosting, adding flavor is one of the easiest tweaks you can make. A teaspoon of your favorite extract—whether it’s almond, peppermint or vanilla—would be a great addition. Cocoa powder would be perfect, too.
Otherwise, Nutella, cream cheese, peanut butter or another nut butter would give it tons of flavor as well as some added smoothness.
Make it less sweet
We all know how store-bought frosting is almost candy-sweet. Some of us love it, and some of us don’t. If you’re the latter (like me), you can tone down the sweetness by adding a sprinkle of salt. Just be careful—it’s easy to overdo and hard to recover from.
