How to Make Old-Fashioned Peanut Butter Cake
- Prepare the Oven and Pan
Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan or line it with parchment paper. - Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside. - Cream the Butter, Peanut Butter, and Sugars
In a large bowl, use an electric mixer to cream the softened butter and peanut butter together until smooth. Add the granulated sugar and brown sugar, beating until light and fluffy. - Add the Eggs and Vanilla
Beat in the eggs one at a time, then add the vanilla extract, mixing until well combined. - Combine Wet and Dry Ingredients
With the mixer on low speed, alternate adding the dry ingredients and buttermilk to the peanut butter mixture, beginning and ending with the dry ingredients. Mix until just combined; avoid overmixing. - Bake the Cake
Pour the batter into the prepared pan, spreading it evenly. Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool completely in the pan. - Prepare the Peanut Butter Frosting
In a mixing bowl, beat the softened butter and peanut butter until creamy. Gradually add the powdered sugar, mixing until smooth. Add the vanilla extract and 2 tablespoons of milk, adding more milk as needed to reach a smooth, spreadable consistency. - Frost the Cake
Spread the peanut butter frosting over the cooled cake in an even layer. Sprinkle with chopped peanuts if desired. - Serve and Enjoy
Slice the cake into squares and enjoy the nostalgic taste of old-fashioned peanut butter goodness!
