Chocolate Peanut Butter Crazy Cake Ingredients
- Flour - all-purpose flour
- Cocoa - unsweetened cocoa powder
- Sugar - granulated sugar

- Salt
- Vinegar - apple cider vinegar
- Vanilla - pure vanilla extract
- Oil - vegetable oil
- Water
- Butter - unsalted butter

Vinegar is an important ingredient in this recipe doing the work the eggs would do in other recipes. Working as an acid, it reacts with the baking soda to give the cake the desired texture. Lemon juice could also be substituted for the vinegar, substituting 1 teaspoon of vinegar with 2 teaspoons of lemon juice.
If there are bubbles in your batter after pouring it into the baking pans, gently tap the cake pan on the counter to release the bubbles. Once the pans are in the oven, keep a close eye on the cake at the 30-minute mark as you don’t want to overbake it.
If you prefer not to use the peanut butter icing, you could also top your cake with your favorite frosting instead. You could also skip the icing and simply dust the top of the cake with powdered sugar. For a bit of extra flavor and texture, you can garnish your cake with colorful sprinkles, mini chocolate chips, or peanut butter chips.
How to Make Chocolate Peanut Butter Crazy Cake
FIRST STEP: Preheat the oven to 350°F. Lightly spray an 8x8 baking dish with nonstick cooking spray (all of the cake ingredients will be mixed in the baking dish).
SECOND STEP: Add the flour, cocoa powder, sugar, baking soda, and salt to the baking dish. Whisk the dry ingredients together until well combined.
THIRD STEP: Using a dry ladle or small measuring cup, make 2 small round impressions and 1 larger impression in the dry ingredients.
FOURTH STEP: Pour the vinegar into 1 of the small impressions. Pour the vanilla into the 2nd small impression, and pour the vegetable oil into the largest impression. Pour the water over all of the ingredients.

FIFTH STEP: Use a wooden spoon to stir all the ingredients together, making sure to get into the corners. Stir until all of the ingredients are well incorporated, and no dry streaks are visible.
SIXTH STEP: Bake the cake on the middle rack, for 30-35 minutes or until a knife inserted comes out clean. Allow the cake to cool completely before icing.
SEVENTH STEP: If using a stand mixer, or a medium-size mixing bowl and a handheld mixer on medium-high speed, cream the butter and creamy peanut butter until no streaks of butter are visible.
EIGHTH STEP: Lower the mixer speed to low and add the vanilla and half and half. Mix for another 30 seconds.
NINTH STEP: Keeping the mixer speed on low, slowly add the powdered sugar ½ cup at a time. Once all powdered sugar has been added, increase the mixer speed to medium and mix until the icing is smooth, about another 45 seconds to 1 minute.
TENTH STEP: Using a silicone spatula, frost the cake.
