These might just be the best keto donuts ever. These sweet cinnamon scented donuts feature a rich brown butter glaze. So good, you'd never believe they are low carb and sugar-free.
Preheat the oven to 325ºF and grease 8 wells of a donut pan (If your pan only holds 6, you can make muffins with the remaining batter or work in batches).
In a large bowl, whisk together teh almond flour, sweetener, protein powder, baking powder, cinnamon, and salt. Stir in the eggs, melted butter, almond milk, and vanilla extract until well combined.
Fill the donut pan wells approximately ⅔ full and bake 15 to 18 minutes, or until the donuts are lightly browned and just firm to the touch. Let cool in the pan 15 minutes, then flip out onto a wire rack to cool completely.
Glaze
Melt the butter in small skillet or saucepan over medium heat. Cook until the butter is browned and fragrant, about 4 minutes. Remove from heat and let cool about 10 minutes.
Place the powdered sweetener in a medium bowl. Slowly whisk in the browned butter until well combined. The mixture will be quite thick. Stir in 1 tablespoon of the cream at a time until a spreadable consistency is achieved. Stir in the vanilla extract.
Spread glaze on cooled donuts and let set, about 20 minutes.

Notes
How many donuts you get will depend on the size of your donut pan. Some are a little bigger than others. If you only have unflavored protein powder, use that plus another ¼ teaspoon vanilla extract. Storage Information: Store the donuts on the counter in a covered container for up to 4 days, or in the fridge for up to a week. You can also freeze them for several months, with or without the glaze.
