Peanut Butter Cake w/ PB Cream Cheese Frosting

Annette W.


Thea, this one's for you!!
Someone in the "Looking for.." group asked about Peanut Butter Cake and I knew I had one so I got out my recipe box from my grandma and started looking. I haven't made this in years but OMG is is heaven on a plate. It is moist, rich, sweet but not too overwhelming in any of those categories. This cake is truly a treat. You will impress anyone and everyone with this recipe.

I have fond memories of making it with my grandma. I can almost smell her kitchen now while it baked. The trick was keeping everyone out of it until after dinner. Grandma and I included!

How to Make Peanut Butter Cake w/ PB Cream Cheese Frosting


  1. Preheat oven to 350°. Bring the butter, peanut butter and water to a boil. Stir until well mixed and remove from heat.
  2. Sift flour, granulated sugar, baking powder, baking soda and cinnamon into a separate bowl. Add brown sugar.
  3. Mix together dry ingredients and boiled mixture. Stir until blended, then add buttermilk, eggs and vanilla.
  4. Pour into a well prepared 9x13 cake pan and bake for 30-45 minutes. The time will vary based on oven temperature and age of ovens. Start with 30 and then check with a tooth pick in the center of cake.
  5. While cake is baking, prepare Peanut Butter Cream Cheese Frosting with a mixer, beat the cream cheese until smooth. Then add the butter and beat until both are incorporated. Add the peanut butter and mix. With the mixer on low, add the powdered sugar and vanilla extract and beat until smooth. Add the last two tablespoons of peanut butter and fold in with a spatula. This will give the frosting a pretty, marbled look. Frost the cake when cool. Enjoy!
  6. If you're making Peanut Butter Icing instead, over medium heat, blend peanut butter, milk, vanilla and butter. Once mixed well, remove from heat. Add powdered sugar and stir until well blended. Spread over warm cake and Enjoy!
