Keto Vanilla Cupcakes Recipe (Only 1g Net Carb!)

When I crave a classic dessert but want to stick to my healthy eating goals, nothing beats a batch of freshly baked vanilla cupcakes. This simple, tried-and-proven recipe is my absolute go-to when I need to satisfy my cake cravings without the guilt!

What makes these cupcakes so special is that they are completely gluten-free and keto-friendly. By swapping out traditional wheat flour for a blend of coconut and almond flour, each delicious serving comes out to just 1 net carb! They are incredibly light, fluffy, and guaranteed to bring a smile to your face.

Ingredients You Will Need

To get that perfect sponge texture without the carbs, you will need a few specialized keto baking ingredients. Here is exactly what goes into my favorite recipe:

For the Sponge:

• 115 g (4 oz / 1 stick) butter, melted
• 130 g (4.5 oz / 1/2 cup) granulated keto sweetener (like Erythritol or Monk Fruit)
• 1/4 tsp salt
• 1 tsp vanilla extract
• 6 large eggs (at room temperature)
• 2 tbsp double cream (heavy cream)
• 65 g (2.3 oz / 1/2 cup) coconut flour
• 4 tbsp almond flour
• 1 tbsp xanthan gum (crucial for binding gluten-free flour!)
• 1 tsp baking powder

For the Keto Buttercream:

• 115 g (4 oz / 1 stick) butter, softened to room temperature
• 4 tbsp powdered keto sweetener
• 1/2 tsp vanilla extract
• 1 tbsp double cream (heavy cream)

Step-by-Step Baking Method

Step 1: Prep the Oven and Pan
Heat your stove to 180°C (160°C fan / 350°F / Gas Mark 4). Line a standard muffin tin with 12 paper or silicone cupcake cases.

Step 2: Mix the Wet Ingredients
First, prepare the sponge. In a large mixing bowl, thoroughly whisk together the melted butter, granulated sweetener, salt, vanilla extract, eggs, and double cream until completely smooth and even.

Step 3: Combine Dry and Wet
In a second bowl, whisk together the coconut flour, almond flour, xanthan gum, and baking powder. Toss these dry ingredients into your creamy butter mixture, and stir well to combine. The batter will be pretty thick but still spoonable. (Pro tip: If you think the mixture is too bulky, add another 1-2 tbsp of cream. If it appears a little thin, add more coconut flour 1 tbsp at a time until it is more batter-like.)

Step 4: Bake to Perfection
Divide the batter evenly between the cupcake cases; they should be about three-quarters full. Slide the cakes into the oven for 18–20 minutes, or until golden brown. A skewer or toothpick inserted into the center should come out clean.

Step 5: Cool the Cupcakes
Remove the tin from the oven and let the cakes cool in the pan for 5-10 minutes. Afterward, delicately move them to a wire cooling rack to cool completely before frosting.

Step 6: Make the Buttercream Frosting
While the cakes cool, prepare the frosting. Use an electric whisk or a wooden spoon to cream together the softened butter, powdered sweetener, vanilla, and double cream until well incorporated, and the icing is light and fluffy. Once the cakes are completely cool, use a piping bag or palette knife to frost them. Top with a slice of fresh kiwi and a few fresh cranberries for a beautiful presentation!
