    How to Make Keto American Flag Cake

    To Make the Keto Vanilla Cake

    Preheat your oven to 350F.

    In the meantime, add the flour, baking powder, oat fiber and salt to a bowl and whisk together, then set aside.

    Separate the eggs, and set yolks aside.  Whip up the egg whites until you have soft peaks.

    Add the Swerve to the egg yolks and mix.

    Then add the sour cream, vanilla extract and vanilla bean paste, and continue mixing. If you don't have vanilla bean paste, you can add an additional tsp of vanilla extract.

    Add the dry ingredients into the wet and mix by hand.

    Then gently fold in the egg whites until combined.

    Transfer the batter to an 8" x  8" glass baking dish sprayed with nonstick spray.

    Bake for 30-35 minutes or until a toothpick, when inserted, comes out clean.

    To Make the Sugar Free Frosting

    Whip the Mascarpone and cream cheese together in a bowl using a hand mixer.

    Add ⅓ cup of the heavy cream, Swerve confectioners and vanilla extract, then mix until smooth and creamy.  Add more of the heavy cream if needed, to get your desired consistency.

    To Assemble the Gluten Free Cake

    Once the cake has cooled completely, add the frosting on top and smooth using a spatula.  Add the blueberries in the top left corner to represents the stars.  Add the slices of strawberries in rows, alternating with rows that have only frosting.  Sprinkle the shredded coconut to fill in the white stripes.  And once completed, should like something like this...

    It looks almost too pretty to cut, but go ahead because it taste even better!

    Is This a Keto Friendly Cake?

    Because this is an almond flour cake recipe, the carbs are significantly reduced which makes it perfectly fine for Keto or low carb diets.

    This gluten free cake has 5 net carbs per serving (not counting the fruit you add) so with a little planning ahead with your macros, there's no reason you can't enjoy this cake as a treat!

    What are the Carbs in Berries?

    The carbs in berries vary depending on the type. Here're the most commonly used berries in Keto desserts and approximate net carbs per ½ cup serving:

    • Carbs in Blueberries- 9 net g of carbs
    • Carbs in Strawberries- 5 net g of carbs
    • Carbs in Blackberries- 3.5 net g of carbs
    • Carbs in Raspberries- 3 net g of carbs

    What is Oat Fiber? Is Oat Fiber Keto?

    Oat Fiber is made from grinding the outer husks of oats. How healthy is oat fiber? It's pure insoluble fiber, which doesn't dissolve in water and isn't broken down in the digestive tract, so it has zero net carbs and is perfect for a Keto Diet. It helps give a more traditional texture and that's why I use it so often. Check out all the Keto Oat Fiber Recipes you can make!

    What is a Substitute for Oat Fiber?

    To get the best results, it's best to use oat fiber if you can. If you're unable to find it, try a combination of psyllium husk powder and coconut flour. Since both are very absorbent, you might have to add more liquid.
