Preheat the oven to 350° Fahrenheit, and heavily grease a 12-cavity donut pan with either an olive oil or avocado oil cooking spray.
Mix the protein powder, almond flour, sweetener, baking powder, salt, cinnamon, and espresso powder in a medium-sized mixing bowl until evenly combined.
Next, add the cream, eggs, and coffee. Miix again until well combined. Whip the batter for a couple of minutes, by hand or with a stand mixer, until you have a smooth and slightly airy batter.
Spoon the batter into the donut cavities. Using a spoon, spread it out as evenly as possible, but don’t stress it if it’s not perfect! It will even itself out somewhat as it bakes.
Spoon or pour the batter into the prepared pan, filling each cavity about two-thirds full. Bake for 18-20 minutes or until set and firm to the touch.
Remove from the oven and let them cool completely before turning them out on a wire rack.I can’t stress the importance of letting these donuts completely cool! The first time I made donuts I got anxious and tried to turn them out while still warm. The result was donut crumbles, and while they tasted good it wasn’t the result I was after! After the donuts have cooled, whisk together the sweetener and two tablespoons of cream in a small mixing bowl until smooth.If your glaze is too thick add more cream a teaspoon at a time until the desired consistency has been achieved. Dip the tops of each donut into the glaze, and place on a wire rack until set.
Pour yourself a cup of coffee, serve, and enjoy!
