2 1/2 cups all purpose flour
2 1/2 teaspoons baking powder
1/2 teaspoon salt
2/3 cup unsalted butter
1 3/4 cups sugar
1 1/2 teaspoons vanilla bean paste or vanilla extract
1 1/4 cups whole milk
Grease two 8" round baking pans or one 9"x13" pan. Line bottom of pan with parchment paper. Grease parchment paper and flour entire pan. Preheat oven to 375F.
Combine flour, baking powder and salt and set aside.
Beat butter on medium high speed for 30 seconds. Add sugar and vanilla and beat until light and fluffy. Add eggs, one at a itme, beating one minute after each. Add dry mixture and milk alternately, beating on low speed after each addition until just till combined. Pour batter into prepared pans.
Bake in a 375F oven for 30-35 minutes or until a toothpick comes out clean. Cool in pan on wire rack for 10 minutes. Then turn out of pan and cool completely on wire rack lined with parchment paper. I usually wrap my cakes in 3 layers of saran wrap before they completely cool and freeze them at least overnight.
