Preheat the Oven

Set your oven to 350°F (175°C). Lightly grease two 8-inch round cake pans and line the bottoms with parchment paper to ensure easy removal after baking.

Prepare Dry Ingredients

In a large mixing bowl, whisk together the almond flour, gluten-free all-purpose flour, sugar, baking powder, and salt. Make sure the ingredients are well combined for an even texture.

Add Wet Ingredients

Pour in the almond milk, apple cider vinegar, and vanilla extract. Stir gently until the ingredients are just combined. Be careful not to overmix, as this can affect the texture of the cake.

Bake the Cake

Divide the batter evenly between the two prepared cake pans. Place them in the preheated oven and bake for 30 to 35 minutes. To test for doneness, insert a toothpick into the center of the cakes. If it comes out clean, the cakes are ready.

Cool the Cakes

Allow the cakes to cool completely in the pans. Once cooled, carefully remove them from the pans and place them on a wire rack to cool further.

Prepare the Icing

In a medium bowl, mix the softened vegan butter (if using), powdered sugar, almond milk, and vanilla extract. Stir until smooth, adjusting the consistency with more milk or powdered sugar if needed.

Assemble the Cake

Once the cakes are completely cool, spread a layer of icing evenly on the top of one cake. Place the second cake on top and frost the entire cake. If desired, decorate with sprinkles for a festive touch.
