Creating the Keto Vanilla Birthday Cake is a straightforward process. Just follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans with butter or cooking spray.
2. Mix Dry Ingredients: In a bowl, combine the almond flour, erythritol, baking powder, and salt. Mix well to ensure even distribution of the dry ingredients.
3. Cream Butter and Sweetener: In a separate large bowl, beat the softened butter and erythritol together until light and fluffy.
4. Add Eggs and Vanilla: Add the eggs one at a time, mixing well after each addition. Then, stir in the vanilla extract.
5. Combine Mixtures: Gradually add the dry ingredient mixture to the wet ingredients, alternating with the coconut milk. Mix until everything is well combined and smooth.
6. Divide the Batter: Pour the batter evenly into the prepared cake pans.
7. Bake: Place the pans in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
8. Cool the Cakes: Once baked, remove the cakes from the oven and let them cool in the pans for about 15 minutes. Then, carefully transfer them to wire racks to cool completely.
9. Frost the Cake: Once cooled, you can frost the cake with keto-friendly frosting or whipped cream if desired.
10. Decorate: Feel free to add fresh berries or nuts on top to enhance the visual appeal.

These steps will guide you in creating this incredible cake effortlessly.
