Ingredients
Keto Vanilla Cake
- 1 ½ cups blanched almond flour
- ½ cup coconut flour
- ¾ cup unsalted butter melted (use dairy-free if desired)
- 1 cup allulose or preferred keto-friendly sweetener
- ½ cup almond milk
- ¼ cup sour cream combined with almond milk to mimic buttermilk
- 4 large eggs
- 2 tsp baking powder
- ¼ tsp salt
- 1 tsp vanilla extract
Keto Vanilla Buttercream
- 4 tbsp unsalted butter cubed and softened
- 250 g 9 oz cream cheese, softened and cubed
- ½ cup 100 g powdered sweetener (e.g., erythritol or monk fruit blend)
- ¼ cup 60 g sour cream
- 2 tsp vanilla extract
Instructions
Preheat & Prep:
- Start by preheating your oven to 350°F (175°C). Grease an 8-inch cake pan and line the bottom with parchment paper for easy removal.
Mix the Dry Ingredients:
- In a large mixing bowl, whisk together the almond flour, coconut flour, baking powder, and salt until well combined. Set aside.
Make the Buttermilk Substitute:
- In a small bowl, mix the almond milk with the sour cream. Stir until smooth. This acts as a low-carb buttermilk replacement that keeps the cake moist.
Beat Wet Ingredients:
- In a separate bowl, beat the melted butter and allulose until light and fluffy. Add in the eggs one at a time, beating well after each. Stir in the vanilla extract and the buttermilk substitute.
Combine & Pour:
- Slowly add the dry ingredients into the wet mixture, stirring until a thick but smooth batter forms. Do not overmix. Pour into the prepared cake pan and smooth out the top with a spatula.
Bake:
- Bake in the preheated oven for 30–35 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Make the Frosting & Assemble:
- While the cake cools, beat the softened cream cheese and butter together until creamy and smooth. Add the powdered sweetener, sour cream, and vanilla extract. Beat until fluffy and spreadable. Once the cake is fully cooled, spread the frosting evenly over the top. Slice and serve.
