Grease a donut pan with butter or nonstick cooking spray and set aside.
In a large bowl, whisk the almond flour, erythritol, baking powder, xanthun gum, and sea salt until combined.
Use a smaller bowl to combine the eggs, almond milk, melted butter, vanilla extract, and almond extract. Add the wet ingredients to the dry and stir until fairly smooth.
Spoon the batter into the greased donut pan, filling each cup about 2/3 full. Place the pan in the oven and bake for 25 minutes, until browned on top.
Allow the donuts to cool in their pan for 10 minutes then remove to a cooling rack for an additional 20 minutes.
Maple Glaze
While the donuts are baking, melt the butter in a pan and then add erythritol and stir until dissolved (about 5 minutes).
Add the heavy whipping cream, vanilla extract, and sugar free maple syrup. Stir over medium heat for another 5 minutes.
Allow to cool off the heat while the donuts are cooling. Place the donuts on the cooling rack into a baking pan to catch the spill over as you pour the glaze on top. Spoon glaze over the top of each cooled donut while on the cooling rack allowing the glaze to coat the sides.
Let rest until the glaze hardens or place in the refrigerator until ready to serve.
Chef's Notes
You can also substitute maple extract for the sugar free maple syrup. A teaspoon should do the trick, but please experiment. This would cut the carbs further.
