  • 1/2 c 1 stick or 115g unsalted butter
  • 2 oz semi-sweet baking chocolate
  • 2 large eggs at room temperature
  • 3/4 c 150g granulated sugar
  • 2 tsp. vanilla extract
  • 1/2 c 115g sour cream, room temperature
  • 1/2 c 42g unsweetened cocoa powder
  • 3/4 c 95g all-purpose flour
  • 1/2 tsp. baking soda
  • 1 tsp. baking powder
  • 1/4 tsp. salt

Pumpkin Buttercream

  • 1/2 c butter 113g, room temperature
  • 1/2 c 110g pumpkin puree
  • 1 tsp. vanilla
  • 3 c 380g confectioners sugar
  • 1 tbsp. pumpkin spice



  1. Preheat the oven to 350F degrees. This recipe makes 12-14 cupcakes, so prepare one pan (or maybe two) with cupcake liners.

  2. Melt the butter and chocolate together in the microwave. Microwave in 30-second increments, stirring in between each time. Set aside.

  3. In the bowl of a stand mixer with the whisk attachment; add the eggs, sugar, vanilla, and sour cream and whisk on medium speed until smooth. (about 1 minute)

  4. In a medium sized bowl, sift the cocoa powder, flour, baking soda, baking powder, and salt together until thoroughly combined.

  5. Add the cooled butter/chocolate to the stand mixer and whisk until smooth, about 30 seconds.
  6. Slowly add in the flour mixture, about 1/4 cup at a time with the stand mixer on low.
  7. As soon as you are done adding the flour turn the mixer off. (You do not want to over-mix!)
  8. The batter will be very thick.
  9. Fill the cupcake liners 2/3 of the way full with batter. Bake for 15-18 minutes. The center of the cupcake should spring back up if gently pressed.

Pumpkin Buttercream

  2. Once all ingredients are combined, turn mixer speed to medium-high and mix for 2-3 minutes.
  3. Buttercream can be stored for up to 1 month in refrigerator.
