Ingredients

Cake

  • 1 cup (258 g) creamy peanut butter
  • 1 cup (200 g) brown sugar, packed
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • ¼ cup (61 g) buttermilk
  • cups (187.5 g) all-purpose flour
  • ½ teaspoon kosher salt
  • ½ teaspoon baking soda
  • 1 cup zucchini, peeled, shredded, and undrained with no seeds (small to medium size)

Toppings

  • ½ cup (129 g) creamy peanut butter, melted
  • chopped peanuts, optional

Instructions

  • Preheat oven to 350°F and grease a 9-inch round cake pan.
  • In a large bowl, mix together the peanut butter, brown sugar, egg, vanilla extract, and buttermilk until well combined.
  • Add the flour, salt, and baking soda to the peanut butter mixture. (The batter will be dry, but the undrained zucchini will bring in moisture.)
  • Fold in the shredded, undrained zucchini.
  • Pour the batter into the prepared cake pan and bake for 25-30 minutes, or until an inserted toothpick comes out with a few crumbs, but no wet batter.
  • Let the cake cool before adding the melted peanut butter and chopped peanuts (optional).
