Son Number 1 stopped by, ate 2 pieces of cake, and proclaimed it "awesome". So I will make it again. It is easy and has great flavor. Here's the recipe.
Coffee-Cocoa Snack Cake
slightly adapted from Fine Cooking
10 tablespoons very soft butter ( 5 ounces)
1- 2/3 cup granulated sugar
2 large eggs, room temperature
1 teaspoon vanilla extract
1/2 teaspoon salt
1 1/2 cups plus 2 tablespoons unbleached, all purpose flour; 7-1/4 ounces
1/2 cup plus 1/3 cup unsweetened cocoa together- 2-1/2 ounce (not dutch-processed)
1 teaspoon baking soda
1 teaspoon baking powder
3/4 -1 cup of semi-sweet chocolate chips
1-1/2 cups brewed coffee- cooled to warm
confectioners sugar for dusting
Place rack in center of oven and preheat to 350 degrees F.
Grease and flour a 9x9 inch square baking pan. If you are going to remove the cake from the pan, then line the bottom of the pan with parchment paper and grease and flour it.
Do not use a mixer for this cake, except to cream the butter and sugar together, if desired. I just mixed it all by hand. Easy!
Mix softened butter and sugar in a bowl and cream until smooth. Blend in the eggs, one at a time. Stir in vanilla. Sift the dry ingredients together and pour into the batter. Add the coffee and whisk the ingredients until mixture is smooth and mostly free of lumps.
Pour the batter into the prepared pan. Bake for 40-45 minutes, until a toothpick comes out clean. Cool before serving.
If you used parchment paper and are going to remove the cake from the
pan, let the cake sit for 20 minutes before inverting onto another rack.
I left my cake in the pan to cool.
This cake is a bit crumbly in texture. It can be wrapped in plastic and stored at room temperature for up to 5 days.
