Ingredients Needed for your Peanut Butter Texas Sheet Cake Bundt Cake

Peanut Butter Sheet Cake

  • Yellow Cake Mix-a miracle base ingredient because it already contains many ingredients you need…like a leavening agent.
  • Brown Sugar-my favorite kind of sweetener, it is perfect in this cake.
  • Granulated Sugar-the combination of brown and granulated sugar gives this cake just the right amount of sweetness.
  • All Purpose Flour-adding a bit more flour to the cake will give it a pound cake like texture.
  • Peanut Butter-use a good quality creamy type of peanut butter.
  • Vegetable Oil-this recipe only requires a small amount because the peanut butter is providing fat to the cake as well.
  • Eggs-a perfect binder to this cake, eggs are always a great addition.

Peanut Butter Frosting

  • Butter-gives the frosting richness.
  • Peanut Butter-every good peanut butter frosting needs a good quality peanut butter.
  • Milk-is used to thin out the frosting.
  • Powdered Sugar-for sweetness, as well as the body of the frosting.
  • Vanilla Extract-adds great flavor. Be sure to use it after the frosting is off the heat so it doesn’t evaporate.

Easy Instructions to make Peanut Butter Bundt Cake with a Cake Mix

  1. Begin by combining the yellow cake mix, brown sugar, granulated sugar and flour in a large bowl.
  2. Whisk the dry ingredients together to remove any lumps.
  3. Add the peanut butter, water, oil and eggs to the dry ingredients.  Mix using a hand held mixer {or by hand} until everything is nicely incorporated.
  4. Pour the cake batter into a Bundt pan that has been liberally sprayed with nonstick spray.

Bake the cake in a 350 degree oven for 45-50 minutes or until a toothpick inserted in the center comes out with just a few crumbs.

If you wait until the toothpick comes out clean then the cake might end up being too dry.

Remove from the oven and allow the cake to cool in the pan for 10 minutes before inverting it onto your cake plate.

Once you have the cake inverted, allow the cake to cool before turning your attention to the frosting.

How to Make Peanut Butter Frosting

Combine butter, peanut butter and milk in a medium sized saucepan over medium heat.  Whisk the ingredients until everything is melted together but do NOT boil.

Once everything is melted, remove from the heat, add the powdered sugar and whisk until it is incorporated.  Add the vanilla extract and stir to combine.

Pour the frosting over the cooled cake quickly and before it starts to set up.

You may need to use a spoon or offset spatula to spread it slightly.  Allow the frosting to drip over the sides of the Bundt cake.

Frequently Asked Questions

How do you store your peanut butter sheet cake?

Store the Peanut Butter Sheet Cake covered tightly in the refrigerator for up to 4 days.

Can you freeze peanut butter sheet cake?

Yes, you can freeze this Peanut Butter Bundt Cake for up to 3 months.  Defrost at room temperature or in the refrigerator.

I prefer to freeze it without the frosting.  Once the Bundt cake is defrosted completely, add the frosting and serve.

What kind of peanut butter is best for this sheet cake?

Good quality peanut butter like Jif or Skippy are the best for baking.  Natural peanut butter can be used but you may find that the end result is slightly different.  You may also need to add a bit of salt.
