Making the Keto King Cake:

  1. Preheat the Oven:
    • Preheat your oven to 350°F (175°C). Grease and line a round cake pan.
  2. Prepare the Filling:
    • In a small bowl, mix chopped pecans, erythritol, ground cinnamon, and melted butter to create the filling. Set aside.
  3. Mix Dry Ingredients:
    • In a large bowl, whisk together almond flour, coconut flour, whey protein powder, baking powder, baking soda, and salt.
  4. Cream Butter and Sweetener:
    • In a separate bowl, cream together softened butter and erythritol until light and fluffy.
  5. Add Eggs and Vanilla:
    • Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
  6. Incorporate Dry Ingredients:
    • Gradually add the dry ingredients to the wet ingredients, alternating with sour cream and almond milk. Begin and end with the dry ingredients.
  7. Create Layers in the Pan:
    • Spread half of the batter in the prepared cake pan. Sprinkle the filling evenly over the batter. Top with the remaining batter.
  8. Bake to Perfection:
    • Bake in the preheated oven for 30-35 minutes or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely.
  9. Prepare the Icing:
    • In a bowl, mix powdered erythritol, almond milk, and vanilla extract to create the icing. Divide the icing into three bowls and tint each with purple, green, and gold natural food coloring.
  10. Ice the Cake:
    • Once the cake is cooled, ice it with the colored icing in a pattern representing the traditional Mardi Gras colors.
  11. Optional Tradition:
    • If you wish to include the traditional element of hiding a trinket in the cake, insert a small plastic baby into the bottom of the cake after it has cooled.
  12. Slice and Celebrate:
    • Slice the Keto King Cake and revel in the low-carb celebration of Mardi Gras!

Tips for Perfecting Your Keto King Cake:

1. Achieving the Right Consistency:

  • Ensure your butter is softened but not melted for the cake batter. This contributes to a fluffy and well-textured cake.

2. Balancing Sweetness:

  • Adjust the sweetness of the filling and icing according to your taste preferences. Taste as you go and add more or less sweetener as needed.

3. Experiment with Nuts:

  • Feel free to experiment with different nuts for the filling. Chopped almonds or walnuts can be delightful alternatives to pecans.

4. Create Intricate Designs:

  • Get creative with the icing to create intricate designs on the Keto King Cake. Traditional Mardi Gras symbols like fleur-de-lis or masks can add an extra festive touch.

5. Consider Sugar-Free Sprinkles:

  • If available, consider using sugar-free sprinkles in Mardi Gras colors for added decoration and texture.

6. Include a Trinket for Tradition:

  • If you’re hosting a gathering, consider including a small plastic baby trinket in the cake. Tradition dictates that the person who finds the trinket is responsible for hosting the next Mardi Gras celebration.

7. Serve with Keto-Friendly Beverages:

  • Pair your Keto King Cake slices with keto-friendly beverages like unsweetened almond milk, black coffee, or herbal tea for a delightful Mardi Gras experience.

8. Store Properly:

  • Store any leftover Keto King Cake in the refrigerator to maintain freshness. It can be reheated briefly in the oven or enjoyed chilled.


This Keto King Cake recipe offers a delicious and low-carb way to partake in the joyous celebration of Mardi Gras. Whether you’re observing this vibrant tradition or simply craving a festive treat, the flavors of cinnamon, pecans, and colored icing come together in a keto-friendly masterpiece.
