Things You'll Need:
- 1 stick of butter, softened
- 1 cup of creamy style peanut butter
- 4 tbsp. of half-and-half
- 2 1/4 cups of confectionery sugar
- 1 tsp. of vanilla
-
Step 1
Soften the stick of butter in the microwave for 10 seconds. Do not heat any longer or it will melt. If it has a foil wrapping, remove the wrapping first.
-
Step 2
Mix butter and peanut butter together in a medium-sized bowl with an electric mixer. Once the ingredients are blended, put the mixer on medium-high speed and beat until well blended. Add vanilla and continue to blend.
-
Step 3
Add the confectionery sugar alternately with the half-and-half. With the mixer on low speed, slowly add the confectionery sugar. As it thickens, add a small amount of the half-and-half. Continue until you have added all the ingredients.
-
Step 4
Set the mixer on high speed and mix the icing until fluffy. If it is too thick, add a little more of the half-and-half. If it is too thin, add a little more of the confectionery sugar.

Step 5
Frost the cake or brownies. Make sure the cake or brownies are cool before frosting. Brush off loose crumbs. Dip a wide knife in warm water and begin to spread the frosting. The warm water helps smooth the frosting on.
