Step 1

Preheat the oven to 350ºF and grease 8 wells of a donut pan.

Step 2

In a large bowl, whisk together the the yogurt, eggs, oil, and vanilla extract until well combined.

Step 3

Add the almond flour, whey protein, sweetener, baking powder, and salt and whisk until smooth. Add just enough water until you have a thick but pourable consistency.

Step 4

Divide the batter between the wells of the donut pan, filling to about three quarters full. Bake 10 to 15 minutes, until the tops are just firm to the touch. Let cool in the pan.

Step 5

In a medium bowl, beat the cream cheese and butter together until very smooth. Beat in the powdered sweetener.

Step 6

Beat in the cream until you have a spreadable consistency, then beat in the vanilla extract. Spread over the tops of the cooled donuts.

Step 7

Sprinkle with sugar-free sprinkles, if desired.
