Step-by-Step Instructions

Make the Carrot Cake:

Preheat Oven: Preheat your oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment paper.
Mix Dry Ingredients: In a large bowl, whisk together almond flour, coconut flour, baking powder, baking soda, salt, and spices.
Combine Wet Ingredients: In a separate bowl, beat the eggs with almond milk, melted coconut oil or butter, erythritol, and vanilla extract until smooth and creamy.
Combine Wet and Dry: Gradually add the wet ingredients to the dry ingredients and stir until fully incorporated.
Add Carrots and Nuts: Gently fold in the grated carrots and chopped nuts (if using).
Bake: Pour the batter evenly into the prepared pans and bake for 40-45 minutes, or until a toothpick inserted in the center comes out clean. Let the cakes cool completely.

Make the Mascarpone Frosting:

Whip the Cream: In a medium bowl, whip the heavy cream until stiff peaks form.
Mix Mascarpone and Sweetener: In another bowl, beat together mascarpone cheese, erythritol, vanilla extract, and a pinch of salt until smooth and fluffy.
Fold Together: Gently fold the whipped cream into the mascarpone mixture until fully combined.

Assemble the Cake:

Frost the Cake: Once the cakes have completely cooled, place one layer on a serving plate. Spread a layer of frosting over the top. Place the second cake layer on top and frost the top and sides of the entire cake.
Chill and Serve: Chill the cake for 30 minutes to allow the frosting to firm up. Slice and serve chilled.
