This recipe creates enough buttercream for 6-12 cupcakes depending on how generous you’re feeling. To fill and cover a 3 layer 8″ cake, we’d recommend multiplying the recipe by three!

  • 250g confectioner’s sugar / 2 cups
  • 1 teaspoon ground cinnamon
  • 1 teaspoon ground allspice
  • 1 teaspoon ground nutmeg

How to make spiced pumpkin buttercream

Step 1:

Dice your butter and then cream the pieces in a stand-up mixer or in a large bowl and using a hand-mixer. Before adding in any other ingredients you want your butter to be as silky smooth as can be.

Step 2:

Sieve in the icing sugar 50g or 1/2 a cup at a time mixing in well with a wooden spoon and then with the mixer after each sift. Keep testing your buttercream. You should taste equal parts of butter and sugar when it is perfect!

Recipe for Spiced Pumpkin Buttercream

This is definitely an addictive buttercream for us. We think it’s simply perfect with coffee cake for a spiced pumpkin latte taste, sandwiched between moist pumpkin cake for a the pumpkin-obsessed, smothered onto dark chocolate cupcakes for a slightly sweet and bitter taste perfect for grown-ups or added to salted caramel or syrup infused recipes!
