Baked in a square baking pan, you can top this easy peanut butter cake with sliced berries, jam, chocolate chips, yogurt, honey and more.
Non-stick cooking spray
1 cup granulated sugar
1 cup all-purpose flour
3/4 teaspoon kosher salt
3/4 teaspoon baking powder
3/4 teaspoon baking soda
1/2 cup buttermilk
1/4 cup canola oil
1 large egg
1 teaspoon vanilla extract
6 tablespoons water
1/2 cup creamy unsalted, unsweetened peanut butter
Confectioners’ sugar, melted chocolate, yogurt, whipped cream, honey, jam and/or fresh berries for serving
Preheat the oven to 350 degrees F. Spray an 8-inch square baking pan with non-stick cooking spray. Line the bottom with parchment.
In a large bowl, combine the sugar, flour, salt, baking powder and baking soda. In a medium bowl, whisk together the buttermilk, oil, egg, vanilla extract, water and peanut butter. Fold the wet ingredients into the dry ingredients until just combined. Pour the batter into the prepared pan.
Bake until a toothpick inserted into the center of the cake comes out clean, about 30-35 minutes. Cool in the pan for 10 minutes before removing the cake and cooling on a wire rack. Serve warm or at room temperature with desired toppings.
