Ingredients
Dry Ingredients
- 2 cups finely blanched almond flour
- ½ cup unsweetened cocoa powder
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ¾ cup granulated keto sweetener (erythritol or monk fruit blend)
Wet Ingredients
- 4 large eggs, room temperature
- ½ cup melted unsalted butter
- ½ cup unsweetened almond milk
- 1 teaspoon vanilla extract
- ¼ cup sour cream
- 2 tablespoons brewed coffee (optional, enhances chocolate flavor)
Optional Chocolate Frosting
- 4 ounces cream cheese, softened
- ¼ cup butter, softened
- ¼ cup unsweetened cocoa powder
- ½ cup powdered keto sweetener
- 1 teaspoon vanilla extract
- 2–3 tablespoons heavy cream
Equipment Needed
- 8-inch round cake pan
- Mixing bowls
- Electric hand mixer or stand mixer
- Rubber spatula
- Measuring cups and spoons
- Cooling rack
- Wire whisk
Instructions
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C). Grease an 8-inch round cake pan with butter or line the bottom with parchment paper for easy removal.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together the almond flour, cocoa powder, baking powder, baking soda, salt, and keto sweetener until evenly combined. Breaking up any cocoa lumps helps create a smooth batter.
Step 3: Mix the Wet Ingredients
In another bowl, beat the eggs until slightly frothy. Add the melted butter, almond milk, vanilla extract, sour cream, and brewed coffee if using. Mix until smooth and fully combined.
Step 4: Combine the Batter
Gradually pour the wet ingredients into the dry ingredients. Stir gently with a spatula until no dry flour remains. Avoid overmixing, as this can affect the cake’s texture.
The batter should be thick but pourable.
Step 5: Bake
Pour the batter evenly into the prepared cake pan.
Bake for 30–35 minutes, or until a toothpick inserted into the center comes out mostly clean with a few moist crumbs.
Avoid overbaking, as almond flour cakes can dry out if left in the oven too long.
Step 6: Cool
Allow the cake to cool in the pan for 15 minutes before transferring it to a wire rack.
Cool completely before frosting.
Step 7: Prepare the Frosting
Beat together softened cream cheese and butter until smooth.
Mix in cocoa powder, powdered keto sweetener, vanilla extract, and heavy cream.
Beat until creamy and fluffy.
Spread evenly over the cooled cake.
Recipe Tips
- Use finely blanched almond flour for the softest texture.
- Room-temperature eggs blend more evenly into the batter.
- Coffee intensifies the chocolate flavor without making the cake taste like coffee.
- Allow the cake to cool completely before frosting.
- Store leftovers in the refrigerator for the best freshness.
Recipe Variations
- Add sugar-free chocolate chips for extra richness.
- Mix chopped pecans or walnuts into the batter.
- Add peppermint extract for a chocolate mint version.
- Top with fresh raspberries for a refreshing contrast.
- Make cupcakes by dividing the batter into a lined muffin tin and baking for 18–22 minutes.
Storage Instructions
Refrigerate the cake in an airtight container for up to 5 days.
Freeze individual slices for up to 3 months. Wrap each slice tightly in plastic wrap before freezing.
Thaw overnight in the refrigerator before serving.
Serving Suggestions
This keto chocolate cake pairs beautifully with:
- Fresh strawberries
- Sugar-free whipped cream
- Keto vanilla ice cream
- Fresh raspberries
- Hot coffee
- Unsweetened tea
Recipe Notes
Because almond flour contains healthy fats, this cake remains moist longer than many traditional flour-based cakes. For best results, measure almond flour by spooning it into the measuring cup rather than packing it down.
If your keto sweetener is less sweet than standard erythritol, adjust the quantity to your taste. Every brand varies slightly in sweetness.
