Happy 15th Birthday to my rockin son!!!! His love of PB mainly Reeses inspired this cake for his birthday!! Here goes, I used a vintage Wilton piano shaped set of cake pans. round would work just fine 🙂 My daughter even helped with the making of the keys 😉

2 1/4 cups  flour 
2 1/2 teaspoons baking powder
1 teaspoon salt
1 1/4 cups sugar 
About 1/2 cup unsalted butter, at room temperature
1/2 cup Reeses creamy peanut butter 
2 large eggs 
2 teaspoons vanilla extract
2/3 cup milk

1. Preheat oven to 350°. Sift flour, baking powder, and salt into a medium bowl; set aside. In the bowl of a stand mixer, beat sugar, 1/2 cup butter, and peanut butter until creamy. Crack eggs into a small dish (do not beat) and add vanilla. Add eggs to the butter mixture 1 at a time, scraping down the inside of the bowl as needed. Beat in flour mixture and milk in alternating batches, starting and ending with the flour and making sure each addition is fully incorporated before adding the next.
2. Butter and flour 2 round 9-in. cake pans. Divide batter evenly between pans.
3. Bake until golden brown and a toothpick inserted in the center of each cake comes out clean, 25 to 30 minutes.
4. Cool cakes 5 minutes. Invert onto a rack, remove pans, and let cool to room temperature, at least 40 minutes.
