Banana Cake with Milk Chocolate Frosting

I have been baking like crazy lately, and the more I bake, the more I want to bake. It's a good thing I don't have to teach all week - more time to experiment in the kitchen! This weekend, I remembered a cake I loved from childhood - banana cake with chocolate chips and chocolate frosting - and wanted to recreate it. I baked it in a 13 x 9 pan so it was very low-maintenance: No need to assemble layers or turn it out of the pan to cool. Easy to cut into squares of any size, this cake is simple and delicious. Without frosting it would probably be great for breakfast.

Cake:

(adapted from How to be a Domestic Goddess by Nigella Lawson)

1/2 cup butter, melted

3/4 cup sugar

1 tsp vanilla

3 ripe bananas

4 tbsp yogurt or sour cream

2 large eggs

1 tsp baking soda

1/2 tsp baking powder

2 cups flour

1 cup milk chocolate chips

Preheat oven to 350 F.

Grease a 13 x 9 baking dish.

Combine the butter, sugar and vanilla in a stand mixer and mix well.

Mash bananas and add to butter mixture.

Stir in yogurt and eggs, mixing well.

Whisk together the dry ingredients in a separate bowl, then add to the batter, stirring until blended.

Fold in chocolate chips.

Bake for about 25 minutes, or until a toothpick inserted in the center comes out clean.

Set pan on a wire rack to cool.

Frosting:

1 cup milk chocolate chips

1/4 cup butter

1 cup powdered sugar

2 tsp (or more!) milk

Melt the chocolate chips in the microwave or the top of a double boiler and cool slightly.

Place butter and chocolate in the bowl of a stand mixer and beat for 2 minutes on medium-high speed.

Add powdered sugar and continue mixing.

Add the milk about 1/2 tsp at a time until the frosting is a spreadable consistency.
