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

How To Make Keto Vanilla Cake With Buttermilk

1. 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.

2. 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.

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.

Tips And Tricks

1. Gently warming almond milk and eggs before mixing helps the ingredients blend more smoothly. This prevents lumps in the batter and contributes to a tender cake texture.

2. Coconut flour tends to clump easily. Sifting it before combining with other ingredients breaks up lumps and creates a lighter, more uniform batter, which improves the cake’s crumb.

3. Baking powder loses effectiveness over time. Using fresh baking powder ensures the cake rises well, resulting in a fluffy, light texture instead of a dense loaf.

4. Adding eggs slowly allows each to incorporate fully. This helps trap air in the batter, creating a lighter, more airy cake instead of a heavy, dense one.

5. Start checking the cake around 25 minutes to prevent overbaking. Overbaking can dry out the cake, so it’s better to test early and often.

6. Insert a toothpick into the thickest part of the cake. If it comes out clean or with just a few moist crumbs, the cake is done. This simple test avoids undercooking or overcooking.

Why My Recipe Works

My recipe works because it balances keto-friendly ingredients to create a moist, tender cake without using traditional flour or sugar. Almond and coconut flours provide structure and healthy fats, while eggs add moisture and help the cake rise.

The combination of almond milk and sour cream mimics buttermilk’s acidity, which tenderizes the crumb and enhances flavor. Using a keto sweetener like allulose keeps sweetness low-carb without bitterness.

Careful mixing and baking times ensure the right texture and avoid dryness. Overall, this recipe achieves a classic vanilla cake taste and texture while staying fully keto-compliant.

This Keto Vanilla Cake with Buttermilk offers several health benefits. Made with almond and coconut flours, it provides healthy fats and fiber, which support digestion and steady energy levels.

My Favorite Ways To Serve It Up
