Ingredients

2 3/4 cups gluten-free all-purpose flour (I used King Arthur Measure for Measure)

1 3/4 teaspoons baking powder

1 teaspoon kosher salt

1/4 teaspoon baking soda

2 teaspoons ground cinnamon

3/4 teaspoon ground nutmeg

1/2 teaspoon ground ginger

1/4 teaspoon ground allspice

1 cup vegetable oil

1 1/2 cups light brown sugar

1 cup granulated sugar

2 teaspoons pure vanilla extract

3 large eggs at room temperature

1 large egg yolk at room temperature

1 (15 ounce) can of sweet potato puree

1/2 cup lactose-free sour cream

Directions

(1) Prepare: Preheat the oven to 350 degrees F. Grease one 13x9x2-inch pan or two 9-inch round pans and line the bottom with parchment paper.

(2) Combine the dry ingredients: In a medium-sized bowl, whisk together the gluten-free flour, baking powder, salt, baking soda, and spices.

(3) Combine the wet ingredients: In the bowl of the stand mixer fitted with paddle attachment mix together the oil, sugars, and vanilla. Add the eggs and extra egg yolk, one at a time, and beat on medium speed until smooth between each addition. Add the sweet potato and the sour cream and beat until smooth.

(4) Blend the cake: Add the dry ingredients to the wet in two parts and, mix on low just until the flour disappears—do not over-mix.

(5) Bake the cake: Transfer the batter to the prepared pan and smooth the top with a rubber spatula. Bake for 30 to 35 minutes until a toothpick comes out with only a moist crumb or two.

(6) Finish: Let cool until easy to handle, then run a butter knife around the edges, releasing it from the pan. Invert the cake onto a cooling rack, flipping it right side up to cool to room temperature.

Make-ahead note: At this point, the cake will keep in an airtight container at room temperature for 2-3 days. when I made this cake, I baked the cake on day 1 and then frosted it on day 2. It was delicious!

(7) Frost the cake: When ready to frost the cake, make our best cream cheese frosting then frost.

(8) Plate and serve: Slice and serve and watch your family, friends, or guests marvel at what a moist and delicious cake you have made!

Pro tips: To bring eggs up to room temperature quickly, simply put them in a bowl of warm (not hot) water for a few minutes.

This cake would be delicious and would work well, as a sheet cake or cupcakes too. Just modify your cooking time so they don’t overcook.
