Let’s Make it Together
Preheat Your Oven: Start by preheating your oven to 350°F (175°C). Prepare two 9-inch round cake pans by greasing them lightly with cooking spray or butter.
Mix Dry Ingredients: In a bowl, whisk together flour and baking powder until well combined. This will ensure even rising when you bake your masterpiece!
Cream Butter and Sugar: In another bowl, beat softened unsalted butter with granulated sugar until light and fluffy—about 3 minutes should do it! The mixture should look pale and airy.
Add Eggs and Peanut Butter: Beat in eggs one at a time followed by creamy peanut butter until fully combined. Embrace those smooth textures!
Combine Wet and Dry Ingredients: Alternately add flour mixture and milk into the peanut butter blend—start with flour, then milk, ending with flour. Stir gently until just combined; overmixing can lead to tough cake.
Bake and Cool Cake Layers : Pour batter evenly into prepared pans and bake for about 25-30 minutes or until golden brown. Let them cool in pans for 10 minutes before transferring to wire racks.
Prepare Frosting : In a mixing bowl, beat softened cream cheese with powdered sugar until smooth. Add remaining peanut butter along with vanilla extract while mixing until creamy perfection is reached.
Enjoy layering your cool cakes with generous amounts of frosting between them before slathering more on top!
