1/4 C. all-purpose flour
1/4 C. milk
3/4 C. unsalted butter divided, at room temp
1/2 C. crunchy peanut butter
2 C. confectioner’s sugar
1/2 t. vanilla extract

Heat oven to 350°F. Prepare cake mix and bake according to package directions in two 9″ round cake pans. Cool layers completely.
In medium nonstick saucepan, whisk flour and milk over medium heat. Cook 1 to 2 minutes, until thickened, whisking to keep mixture smooth. Remove from heat; stir in 1 Tbsp butter. Refrigerate.
In large bowl, with electric mixer on medium, beat the remaining butter and peanut butter 1 minute or until smooth. Gradually beat in sugar and vanilla on low. Slowly add flour mixture, continue beating until light and fluffy.
