It’s Friday, it’s supposed to get into the 50’s, and I have half a pan of this banana snack cake sitting on my counter. It’s going to be a good day!

While it being Friday is pretty exciting and this cake tastes amazing, I’m pretty sure I’m most excited about the fact that it is supposed to be warm and sunny today!

Well, that and the fact that I got new running shoes in the mail yesterday that are just waiting for me to run in them, and the idea of running in the warmth is wonderful!

But after enjoying a long run in the warm, sunny weather, you can guarantee that we will enjoy big pieces of this banana cake. It’s perfect recovery food after all. . .whole wheat flour, bananas, honey, yogurt, peanut butter. . .just think of it as a smoothie in cake form! 🙂

Okay, well maybe it’s not a health food, but it is a lot healthier than most cakes.

It doesn’t, however, taste like healthy cake. The whole wheat flour is sifted so it doesn’t give the cake a heavy or coarse texture. The bananas and yogurt give the cake it’s tender, moist base so that you won’t miss the oil.

And the frosting? Well, that’s good enough to eat all by itself! But you should save some of it to frost the cake.

It is rich and creamy without being overly sweet. Spread it on top of the banana cake and you will find yourself having a hard time resisting a second piece!

What a lovely way to have cake! I love healthier substitutions in baked goods, especially when they don't taste like "healthy" desserts!
