To fill and frost the cake I used Swiss Meringue Buttercream flavored with Maple Flavoring. This buttercream is easy to work with and it pipes beautifully onto the cakes and cupcakes.

Swiss Buttercream is a perfect medium for making piped cake decorations. It freezes well, and decorations hold up nicely on the cake. I used it to make cute piped buttercream pumpkins, leaves, flowers, and wreath branches.

To color Swiss Buttercream I used gel food colors. If you haven’t colored Swiss Buttercream before, follow my tutorial on How to Color Swiss Buttercream. It will help you achieve deep, rich colors.

Pumpkin Spice Sponge Cake

  • 4 egg whites
  • 4 egg yolks
  • 3/4 cup pumpkin puree
  • 200 grams sugar
  • 4 tbsp oil vegetable, coconut
  • 4 tbsp warm water
  • 200 grams all purpose flour
  • 1 1/2 tsp baking powder
  • 1/2 tsp salt
  • 1/2 tsp vanilla extract
  • 1 tsp ground cinnamon
  • 1/4 tsp ground nutmeg
  • 1/4 tsp ginger
  • 1/8 tsp ground cloves

Maple Swiss Buttercream

  • 2 batches Swiss Buttercream (recipe in notes)
  • Maple Flavoring


Pumpkin Spice Sponge Cake

  • Preheat oven 350F.
  • Butter and flour your baking pans, line the bottom with parchment.
  • In a medium bowl sift together flour (200grams), cinnamon(1tsp), nutmeg(1/4tsp), ginger(1/4tsp), cloves(1/8tsp), salt(1/2tsp) and baking powder (1 tsp and 1/2tsp). Set aside.
  • In a clean bowl, whip egg whites (4), once soft peaks are formed, gradually add 1/2 of the sugar (100grams). Beat until shiny and stiff peaks are formed. Don’t whip it too long though, you want the egg whites to retain moisture. Turn the mixer off at once when stiff peaks are formed.
  • Scrape the meringue into another bowl. Set aside. Put all the egg yolks (4) into the mixing bowl you just used for making the meringue. It is okay, it doesn’t have to be spotless. Add remaining sugar (100 grams) to the egg yolks. Using same wire whip attachment mix the egg yolks with sugar. First at medium speed and then at high speed. Once your egg yolks have doubled in volume and became pale in color (ribbon stage) add pumpkin puree. Beat till well blended together.
    Then gradually add oil (4tbsp), by tablespoon, mixing well after each addition.
    then add warm water (4tbsp), by tablespoon, mixing well after each addition. Add vanilla extract (1/2tsp) and beat until combined. Turn off the mixer.
  • Using fine mesh strainer sift about 1/3 of flour mixture into the egg yolk pumpkin mixture and carefully fold the flour in with a spatula, then add about 1/3 of meringue and fold iit in. Continue with rest of the flour and meringue until no flour streaks are visible. Be gentle and don’t over mix. You are looking for a light and airy batter.
  • Fill your buttered and floured pans and bake until tooth pick inserted in the center comes out clean, about 25-30 minutes. Let cool slightly, remove from the baking pans, and cool completely before filling and decorating.

Swiss Meringue Buttercream

  • Make 2 batches of Swiss Buttercream (link to the recipe in the post and in recipe notes).
    Flavor buttercream with Maple Flavoring. Use only several drops, start with 10 drops. Blend in and taste. Add more flavoring if desired. Buttercream can be prepared ahead of time. Store it in the fridge. Let it come to room temperature before using. If necessary whip it again for couple of minutes.
    Buttercream can also be frozen for up to 3 months.
