Add the flour, baking powder, oat fiber, pumpkin pie spice and salt to a bowl and whisk together, then set aside.
Whip up the egg whites using a hand mixer until you have soft peaks. Add the swerve and wet ingredients to a separate bowl and mix.
Add the dry ingredients into the wet and mix by hand. Then fold in the egg whites until combined. Scoop into a piping bag (or food storage bag), cut off the tip and pipe into a silicone donut pan sprayed with nonstick spray.
Bake for 20 minutes or until a toothpick, when inserted comes out clean. Then allow to cool on a wire rack while you make the glaze.
To Make the Glaze
Add the cream cheese to a bowl and gently heat in the microwave to soften, but do not completely melt it. Add in the maple and vanilla extracts, then the swerve (according to the level of sweetness you prefer) and heavy cream. Add more heavy cream or hot water as needed to get your desired consistency.
Dip each donut into the glaze and set back on the wire rack. You can glaze just the top, top and bottom of double dip for more of a frosting.
I double dipped them, so they are more frosted than glazed. I made mine sweet, but not as sweet as a typical non-Keto glaze. You can experiment with one and see if you prefer the glaze or frosting.
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!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.
