Ingredients:
- 375g all-purpose flour
- 10g baking powder
- 5g baking soda
- 3g kosher salt
- 15g pumpkin pie spice
- 113g unsalted butter, melted
- 120ml vegetable oil
- 200g granulated sugar
- 200g dark brown sugar, packed
- 4 large eggs, room temperature
- 425g pumpkin puree
- 10ml vanilla extract
- 450g full-fat cream cheese, cold
- 225g unsalted butter, slightly softened
- 600g powdered sugar, sifted
- 30ml heavy cream, cold
- 1g salt
Instructions:
- Preheat oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper.
- In a small bowl, stir the 15g pumpkin pie spice into the 113g melted butter and let bloom for 5 minutes to release fat-soluble aromatics.
- In a large mixing bowl, whisk together the vegetable oil, spiced butter, granulated sugar, and dark brown sugar until fully combined.
- Add eggs one at a time to the sugar mixture, whisking vigorously after each addition. Incorporate the pumpkin puree and vanilla extract until the mixture is emulsified and smooth.
- Sift the flour, baking powder, baking soda, and salt. Gently fold the dry ingredients into the wet ingredients until no flour streaks remain.
- Divide the batter evenly between the three prepared pans. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
- Cool cakes in the pans for 10 minutes before transferring to wire racks to cool completely.
- To make the frosting: Beat the cold cream cheese and softened butter together until smooth. Gradually add powdered sugar, followed by heavy cream and salt, whipping until fluffy and stabilized.
- Stack the cooled cake layers with frosting between each, then cover the top and sides with the remaining cream cheese frosting.
