Ingredients

5 Large Eggs (separated)

1/4 tsp Cream of Tartar

6 tbsp Melted Butter (divided)

1 tsp Vanilla

4 oz Cream Cheese (softened)

1/4 cup + 2 tbsp Erythritol (divided)

2 tsp Baking Powder

1 cup Almond Flour

2 tsp Cinnamon (divided)

2 tbsp Butter (softened)

1 oz Cream Cheese (softened)

2-3 tbsp Heavy Whipping Cream

3 tbsp Confectioners Erythritol (or powdered erythritol made by pulsing granular erythritol)

1/2 tsp Vanilla

6 tsp Granular Erythritol (divided)

2 drops Yellow Food Coloring

2 drops Green Food Coloring

1 drop Red Food Coloring

1 drop Blue Food Coloring

Instructions

Step 1: Preheat your oven to 350°F and thoroughly grease a Bundt pan.

Step 2: Separate the eggs into two large bowls. Add the cream of tartar to the egg whites and beat with an electric mixer until soft peaks form. Set aside.

Step 3: To the egg yolks, add 3 tablespoons melted butter, vanilla, cream cheese, and 2 tablespoons erythritol. Mix until well combined. Then add 1 teaspoon cinnamon, baking powder, and almond flour, stirring until fully incorporated.

Step 4: Gently fold the beaten egg whites into the almond flour mixture until you have a uniform batter.

Step 5: In a small bowl, combine the remaining 3 tablespoons melted butter, 1 teaspoon cinnamon, and 1/4 cup erythritol.

Step 6: Pour half of the batter into the prepared Bundt pan. Evenly sprinkle the cinnamon/butter/erythritol mixture on top, then cover with the remaining batter, spreading it gently to the edges to cover the cinnamon layer.

Step 7: Use a butter knife to create vertical swirls in the batter, being careful not to mix the layers too much. If including a baby figurine in the cake, now is the time to insert it by pushing it into the batter just until covered.

Step 8: Bake for 30-40 minutes, or until the cake is golden on top. Allow it to cool in the pan before removing.

Step 9: While cooling, prepare the icing by whisking together cream cheese, softened butter, vanilla, erythritol, and 2 tablespoons heavy cream until smooth. Add an extra tablespoon of cream if the frosting is too thick.

Step 10: To make colored sugar, divide 2 teaspoons of erythritol into three bowls. Add 2 drops of yellow food coloring to one, 2 drops of green to another, and for purple, mix 1 drop of blue and 1 drop of red in the third.

Step 11: Once the cake is out of the pan, spread the frosting over the top and sprinkle with the colored sugar for decoration.

Tips & Variations

Pulse granular erythritol in a food processor to create powdered confectioners’ style sweetener if you don’t have it on hand.

For a more festive look, try using food-safe glitter or edible gold dust in addition to colored sugar.

Substitute almond flour with a keto-friendly flour blend to alter texture slightly if desired.

If you want to omit the baby figurine, simply skip that step without affecting the overall cake.

FAQs

Can I make this cake dairy-free?

This recipe relies on cream cheese and butter for texture and flavor, which are key to its keto-friendly richness. To make it dairy-free, you’d need keto-compatible dairy-free substitutes, but results may vary.

Is the baby figurine safe to bake inside the cake?

Yes, using a small, food-safe plastic baby figurine specifically designed for King Cakes is safe, but make sure to clean it thoroughly before insertion. Alternatively, hide the baby in the frosting or place it on top after baking.
