Peanut Butter Frosting for Jeff's Birthday Cake

We had Jeff's birthday dinner tonight, and Katie made the frosting for the cake I baked last night.  The thought of peanut butter frosting didn't really excite me, but then I tasted it - it was light, fluffy, subtle, and delicious.  It wasn't a big wham of peanut butter, either.  There was enough frosting for the 2-layer cake and for a bunch of cupcakes.

It was a small but really nice dinner.  Along with me, Katie, and the boys, Jeff was joined by his Dad Gene and his brother Joe.  Both my boys are good cooks, and Joe made a lemon shrimp appetizer and baked some chicken wings.  Katie's pot roast was delicious.  Henry kept asking if it was time yet, and when it was, he blew out most of the candles, as expected.  We all enjoyed the chocolate cake (gluten-free) with peanut butter frosting.  I used a gluten-free cake mix for the cake, and the frosting was a perfect compliment.  The recipe follows, along with a few photos of a fun birthday night.
