Instructions

Pumpkin Cake

  • Preheat the oven to 350º F. Spray a 9x13 inch cake pan with non-stick cooking spray OR for cupcakes line 2 muffin pans with 24 liners.
  • In a large mixing bowl combine the eggs, vegetable oil, milk and pumpkin puree. Beat lightly with an electric mixer.
    3 large eggs, 1/2 cup (118ml) vegetable oil, 1 cup (236ml) milk, 1 cup (227g) canned pumpkin puree
  • Add in the flour, sugar, cinnamon, nutmeg and spice cake mix. Mix with an electric mixer on low until combined.
    1 cup (120g) all purpose flour, 1/2 cup (99g) granulated sugar, 2 tsp cinnamon, 1/4 tsp nutmeg, 1 box spice cake mix
  • Pour the batter into the prepared cake pan or scoop into the muffin liners, filling 1/2 to 3/4 full.
  • Bake a 9x13 inch cake for 36-38 minutes or the cupcakes for 16-18 minutes, until a toothpick comes out clean. Allow the cake to cool completely before adding the buttercream.

Spiced Frosting

  • In a mixing bowl beat the softened butter using an electric mixer for 1-2 minutes. Add in the powdered sugar (2 cups at a time) and the cinnamon & nutmeg, mixing by hand or on low. Continue to beat in the powdered sugar until the frosting is smooth and tastes good to you! Spread frosting over the cake or pipe onto cupcakes.
