How To Make the Peanut Butter Cake with Peanut Butter Frosting

Step 1: Prepare the Pan and Oven

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan and set aside.

Step 2: Mix the Dry Ingredients

In a bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.

Step 3: Cream the Butter and Sugars

In a large bowl, beat the butter, peanut butter, granulated sugar, and brown sugar until fluffy and light.

Step 4: Add Eggs and Vanilla

Beat in the eggs one at a time, followed by the vanilla extract.

Step 5: Combine Wet and Dry

Alternately add the flour mixture and milk to the wet ingredients, mixing just until combined.
