Equipment
- Stand Mixer with Paddle Attachment
Ingredients
Cake
- 1 cup unsalted butter
- 1 can (15 oz) pumpkin (not pumpkin pie filling)
- ½ cup light or dark brown sugar, lightly packed
- 1 cup granulated sugar
- 4 large eggs
- ½ cup whole buttermilk
- 2 tsp vanilla
- 1 tsp maple extract
- 2 ¼ cups all-purpose flour, fluffed, spooned and leveled
- 1 ¼ tsp baking soda
- 1 tsp coarse Kosher salt (if using table salt, use half the amount)
- 1 ½ tsp ground cinnamon
- 1 tsp ground ginger
- ½ tsp ground cloves
- ¼ tsp ground nutmeg
Buttercream
- 3 cups unsalted butter, softened to room temperature
- 6 cups powdered sugar
- 1 ½ tbsp meringue powder, optional
- 1 tsp coarse Kosher salt (if using table salt, use half the amount)
- 1 tbsp vanilla extract
- 1 tbsp maple extract
Instructions
Cake
- Preheat the oven to 350 F, and spray the bottoms of three 8-inch cake pans with non-stick spray.
- In a saucepan over medium heat, melt the butter. Continue to cook the butter, swirling the pan occasionally, for about 10 minutes, until the water has evaporated, and the butter is forming nutty, fragrant golden brown solids at the bottom of the pan. Remove the pan from the heat and let the butter cool for 10 minutes.
- In a large bowl, whisk together the pumpkin, brown sugar, granulated sugar, eggs, buttermilk, vanilla and maple extract. Whisk in the browned butter.
- In a separate bowl, sift together the flour, baking soda, salt and spices.
- Add the dry ingredients to the wet, and whisk for about 15-30 seconds until smooth.
- Divide the batter between the pans. Bake the cakes on the center oven rack for about 22-25 minutes, until a cake tester or toothpick comes out clean.
- Set the pans on a wire cooling rack, cover loosely with a clean kitchen towel, and cool completely before frosting.
Buttercream
- In the bowl of your stand mixer fitted with the paddle attachment, beat the butter for one minute, until smooth.
- With the mixer on low, add the powdered sugar, meringue powder and salt. Add the vanilla and maple extracts. Increase speed to medium, and whip for 4-5 minutes, scraping the bowl occasionally, until light and fluffy. Turn the speed down to "stir" and mix for 1 more minute.
- Remove the cooled cakes from the pans. Fill, frost and stack the cakes, then frost all over with a thin crumb coat of buttercream. Chill in the fridge for 30 minutes, then finish frosting all over with a final coat of buttercream.
Notes
Store leftover cake in an airtight container at room temperature for up to 3-5 days.
If you will not be frosting the cake with the piped buttercream design shown in this post, you can cut the buttercream recipe in half.
