Ingredients

Cake
  • ¾ cup pumpkin not pumpkin pie filling, puree
  • ¾ cup granulated sugar
  • ¼ cup light brown sugar packed
  • ⅓ cup coconut oil
  • ¼ cup almond milk other milks may be substituted including coconut, soy, rice, cow, preferably at room temp, unsweetened vanilla
  • 2 tablespoons molasses mild or medium
  • 1 tablespoon vanilla extract
  • 1 teaspoon cinnamon
  • 1 teaspoon pumpkin pie spice
  • 1 teaspoon allspice
  • ¾ teaspoon cloves ground
  • ½ teaspoon ground nutmeg
  • pinch salt optional and to taste
  • 1 cup all-purpose flour plus 2 tablespoons
  • 2 teaspoons baking powder
Frosting
  • ¼ cup butter softened (half of 1 stick; use vegan butter to keep recipe vegan, unsalted
  • confectioners’ sugar about 2 cups
  • 3 to 4 tablespoons coffee creamer or sub non-dairy milk, Pumpkin Spice Latte flavor
  • pumpkin pie spice for sprinkling

Instructions

Cake:
    Cup of Yum
  1. Preheat oven to 375F. Line a 9-by-9-inch pan with aluminum foil, spray with cooking spray, or grease and flour the pan; set aside.
  2. In a large mixing bowl, combine all ingredients through optional salt, and whisk to combine. Using room temp milk will prevent coconut oil from re-solidifying, but if it does, a few small white clumps are okay.
  3. Stir in the flour and baking powder until just combined, don’t overmix. Batter is quite thick.
  4. Turn batter out into prepared pan, smoothing the top lightly with a spatula.
  5. Bake for about 27 minutes, or until center is set and a toothpick inserted in the center comes out clean, or with a few moist crumbs, but no batter.
  6. Allow cake to cool in pan, on top of a wire rack, for at least 30 minutes before turning out onto the rack to finish cooling completely. While cake cools, make the frosting.
Frosting:
  1. In a large mixing bowl, combine (vegan) butter, 2 cups confectioners’ sugar, 3 tablespoons creamer, and beat with an electric mixer on medium high speed until smooth. As needed, drizzle in more creamer until desired frosting consistency is reached. If frosting is too loose, add a bit more confectioners’ sugar, playing with the sugar and creamer ratios until desired consistency is reached.
  2. Turn frosting out onto cooled cake, smoothing the top lightly with a spatula. If you have extra frosting, it will keep airtight in the refrigerator for many weeks, and can be used at a future date.
  3. Sprinkle pinches of pumpkin pie spice over the frosting before slicing and serving cake. 

Notes

  • Storage: Cake will keep airtight at room temperature for up to 5 days. I personally am comfortable storing buttercream-frosted items at room temp, but if you prefer to store in the fridge, that’s fine, but note the fridge will dry the cake out more quickly. Unfrosted cake will keep airtight in the freezer for up to 4 months.
