- Bake: Pour the mixture into the prepared pan and bake for 30 minutes, or until a toothpick inserted into the center comes out clean.
- Cool: Let the cake cool on a wire rack until completely cool.

Tips and Tricks for the Perfect Keto Cake
- Cooling is Crucial: Allow the cake to cool completely before icing to prevent the buttercream from melting.
- Sweetener Choice: Using monk fruit sweetener or erythritol sweetener is ideal for keto cake recipes.
- Baking Powder: Double-acting baking powder reacts twice, creating gas bubbles when moisture is added and when heated, resulting in a fluffier cake.
- Almond Flour: Blanched almond flour gives a prettier gluten-free vanilla cake, but natural almond flour or almond meal can also be used. Macadamia flour or cashew meal can replace almond flour, though they are higher in carbs. Coconut flour is not a suitable substitute.
- Serving Suggestions: Use sugar-free sprinkles for an easy vanilla birthday cake.
Storage Instructions
- Refrigeration: Store the keto vanilla cake in an airtight container in the fridge for up to 1 week.
- Freezing: Freeze the cake in an airtight container or ziplock bag for up to 1 month.
