Ingredients

  • 2 cups all-purpose flour, plus more for the pan
  • ¼ cup cornstarch
  • 2 ½ teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • ½ teaspoon ground cinnamon
  • ⅔ cup maple syrup
  • ⅔ cup vegetable oil
  • ⅔ cup organic brown sugar
  • ½ cup unflavored and unsweetened non-dairy milk
  • 1 teaspoon maple extract
  • 1 teaspoon vanilla extract
  • 1 teaspoon apple cider vinegar
  • ¾ cup chopped walnuts

For the Frosting

  • ¾ cup vegan butter, room temperature
  • 2 tablespoons maple syrup
  • 1 teaspoon vanilla extract
  • Pinch salt
  • 2 cups organic powdered sugar, or more as needed

For Garnish

  • Walnut halves, optional

Instructions

  • Preheat the oven to 350°F.
  • Grease and flour the inside of a 9-inch round cake pan.
  • Whisk the flour, cornstarch, baking powder, baking soda, salt, and cinnamon together in a large mixing bowl.
  • In a small bowl or liquid measuring cup, stir together the maple syrup, oil, brown sugar, non-dairy milk, maple extract, vanilla extract, and apple cider vinegar.
  • Pour the maple mixture into the bowl with the flour mixture, then stir the ingredients together just until combined.
  • Fold in the walnuts.
  • Transfer the batter to the prepared baking pan, smoothing out the top with a spatula.
  • Bake the cake for 36 to 40 minutes, until the top is golden brown and a toothpick inserted into the center comes out clean.
  • Place the cake pan on a cooling rack when it comes out of the oven. Let the cake cool completely.
  • To make the frosting, beat the butter on high speed with an electric mixer until creamy, about 1 minute. Beat in the maple syrup, vanilla, and salt.
  • Turn the mixer speed down to medium, then begin beating in the powdered sugar, adding a bit at a time, until the frosting is creamy and fluffy.
  • Once the cake is cool, invert it onto a plate. Spread the frosting over the cake, then optionally garnish with walnut halves.
  • Slice and serve.
