Despite there being virtually thousands of cake recipes available online, they all technically fit into three categories of cake. This includes shortened cakes (utter or oil cakes), shortened cakes (also known as foam cakes), and finally, chiffon cakes.

Shortened cakes regularly contain high amounts of fat, usually in a solid form like butter or margarine. These cakes can be further sub-classified into butter cakes, pound cakes, and oil cakes (or cake mixes).

Unshortened cakes generally contain no fat at all or the most a tiny bit. Cakes containing no fat are called angel food cakes and are very light and fluffy. Then, cakes with only egg yolks include types like sponge cake or jelly roll cakes.

And finally, cakes with oil and fat (along with egg yolks) are genoise cakes and chiffon cakes. Now, technically these are types of foam cakes because of their mixing method. However, because they are so unique, they are often placed into a category of their own.

How To Make An Old School Peanut Butter Cake?

Step 1: Preheat the oven and prepare the equipment

First, start by preheating the oven to 350°F (180°C). Line a 9×13-inch baking pan with non-stick baking paper and some cooking spray.

Then, make sure that all of your ingredients are measured out before starting the baking process.

Step 2: Combine the wet ingredients

First, combine the butter and water in a medium saucepan and bring them to a boil. Once the butter has been completely melted, remove the mixture from the heat and whisk in the peanut butter and vegetable oil. Allow the mixture to cool for about 10 minutes.

Next, whisk in the eggs one at a time. Make sure to whisk each until they are fully incorporated before adding another. Finally, whisk in the vanilla extract or essence.

Step 3: Mix the dry ingredients and finish the batter

Now, in a large mixing bowl, combine all of the dry ingredients. Make sure they are lump-free and well mixed.

Then, whisk the dry ingredients into the wet mixture base. Whisk the ingredients together until they are just combined.

Step 4: Bake the cake

Once your old-school peanut butter cake batter has been made, pour it into your lined baking pan.

Bake the peanut butter cake for 40-45 minutes or until the toothpick comes out clean. Once baked, allow the cake to cool slightly on a wire rack.

Step 5: Make the frosting

While your cake is cooling, you can make your peanut butter frosting. First, combine the butter, peanut butter, and buttermilk in a medium saucepan and bring it to a boil.

Then, remove it from the heat and whisk in the vanilla extract and powdered sugar. Only add about 1 cup of sugar at a time to ensure it doesn’t form any lumps.

Once the sugar has been added, place the mixture back onto a low heat and gently warm it again.

Step 6: Serve your old school peanut butter cake

You can pour your warm peanut butter frosting over your still-warm cake. The frosting will set quickly, so don’t work slowly and ensure it remains warm before you pour it.

Finally, while the frosting is still soft, spread the roasted peanuts over the cake and serve.

Tips And Tricks

  • If you are using unsalted butter for this cake recipe, increase the salt amount to 1 teaspoon.
  • You can make your own buttermilk by combining 1/2 cup regular milk with 1 teaspoon lemon juice. Allow the mixture to sit for 5 minutes before whisking it and using it as-is in this recipe.
  • Your cake is fully baked once a testing needle or toothpick comes out clean and doesn’t contain any batter.
  • To cool your cake, first, cool it inside of its pan for 10 minutes. Then, remove it from the pan and place it on a wire rack until you cover it with frosting.
  • You have to pour the warm frosting over a semi-warm cake. The warm cake will help the frosting spread evenly over it and create a smooth layer.
  • You can adjust the consistency of the frosting by adding more buttermilk to help thin it. To thicken it, you can add more confectioner’s sugar, however, the frosting does set very quickly and you will likely not need to thicken it at all.
