Ingredients

  • 8 oz. sugar-free white cake mix
  • 2/3 cup water
  • 1 egg white
  • 1/3 cup crunchy peanut butter

Instructions

  1. Empty the cake mix into a bowl.
  2. Add water, egg white, and peanut butter to the bowl.
  3. Blend for 4 or 5 minutes or until creamy.
  4. Transfer the batter to an 8-inch greased cake pan.
  5. Bake at 350°F for 20 to 25 minutes.
  6. Allow the cake to cool, then remove from the pan.

Tips & Substitutions

For a fluffier texture, beat the egg white until frothy before adding it to the mix. If you prefer smooth peanut butter, feel free to substitute it for crunchy. This cake is versatile; you can fold in chocolate chips or nuts for added flavor. Make sure to grease the pan well to avoid sticking, especially since this is a quick recipe.

Serving Suggestions

This quick peanut butter cake is delightful on its own but pairs beautifully with a scoop of vanilla ice cream or a dollop of whipped cream for a special touch. Consider serving it alongside a fresh fruit salad for a refreshing contrast. It also makes a great base for a layered dessert, similar to Alice'S Upside-Down Cake, adding different flavors.

Storage & Reheating

Store any leftover cake in an airtight container at room temperature for up to 3 days. For longer storage, wrap it in plastic wrap and refrigerate for up to a week. To reheat, place a slice in the microwave for about 15-20 seconds to enjoy it warm. Avoid overheating to maintain its texture.

Frequently Asked Questions

Can I use a different type of cake mix?

Yes, you can experiment with other flavors of cake mix such as chocolate or banana to create different variations. Just keep in mind that the flavor of the peanut butter will still be prominent, so choose a complementary cake mix for best results.

What can I use instead of egg white?

If you prefer to make this cake egg-free, you can substitute the egg white with 1/4 cup of unsweetened applesauce or a flax egg (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water, let sit until thickened). Both options will help bind the ingredients.

How can I decorate the cake?

You can top the cake with a layer of chocolate frosting or a simple peanut butter glaze made from powdered sugar and peanut butter mixed with a bit of milk. For added texture, sprinkle chopped peanuts or mini chocolate chips on top for a delightful crunch.
