Peanut butter cake with peanut butter frosting
Preheat oven to 350 degrees F (175 degrees C). Grease and flour an 8 inch square pan.
In a large bowl, mix together the flour and sugar. Make a well in the center and pour in the milk, oil, eggs, 2 tablespoons peanut butter and vanilla. Mix well and pour into prepared pan.
Bake in the preheated oven for 30 to 35 minutes, or until a toothpick inserted into the center of the cake comes out clean. Allow to cool.
To make the frosting: In a large bowl, combine 1 cup peanut butter and confectioners' sugar. Beat in vanilla, then milk to desired consistency. Spread on cake.
