How to Make Keto American Flag Cake
Ingredients
For the Cake
2 cups super fine almond flour
1/2 cup Oat Fiber (see notes)
3 eggs, divided
1 1/4 cup sour cream
1/2 cup swerve confectioners
3 teaspoons baking powder
1 teaspoon vanilla bean paste
1 teaspoon vanilla extract
Pinch of salt
For the Frosting
2/3 cup mascarpone cheese, at room temperature
2/3 cup cream cheese, at room temperature
1/4 cup swerve, confectioners (or powdered erythritol)
1/3 cup heavy cream (or as needed)
1 teaspoon vanilla extract
For the Flag
1/4 cup fresh blueberries
3/4 cup fresh strawberries, sliced
1/4 cup unsweetened shredded coconut
Preparation
To make the Cake
Preheat oven to 350F.
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 bean paste, and continue mixing.
Add the dry ingredients into the wet and mix by hand.
Then 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 Frosting
Whip the mascarpone and cream cheese together in a bowl using a hand mixer.
Add 1/3 cup of the heavy cream, swerve confectioners (or powdered erythritol) 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 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…
Note:
The Oat Fiber is really important in this recipe! I use it in so many recipes, because of the amazing texture it gives whatever I am baking! It is hands down, the best ingredient I’ve baked with and is really worth buying. I use Lifesource Foods Oat Fiber 500 because they grind it to a very fine powder and has a mild flavor. I buy it in the 16 ounce bag here. The bag lasts a while, because you don’t need to use much in your recipes.
Oat Fiber, is not the same as Oat Flour, which is made from grinding oats. Oat Fiber is made from grinding the outside husks of oats and is pure insoluble fiber. Insoluble fibers do not dissolve in water and are not broken down in the digestive tract. So it’s low carb and Keto friendly!
These are just some of the great recipes you can make using Oat Fiber:
Lemon Meringue Cupcakes
Blueberry Lemon Muffins
Pumpkin Cupcakes
Chocolate Chip Cookies
Gingerbread Cupcakes with Cream Cheese Frosting
Cheddar Jalapeño “Cornbread”
Blueberry Pancakes
Fluffy Pumpkin Pancakes
Pumpkin Donuts
Cranberry Sauce and Walnut Muffins
Tiramisu Pancakes
