Preheat oven to 325°F (165°C) and grease a 9-inch springform pan. Dust the pan with a bit of almond flour after greasing.
In a large mixing bowl, combine the eggs with the Erythritol, unsweetened almond milk, baking powder, vanilla extract, almond extract, a pinch of sea salt, and melted butter.
Add the almond flour into the mixture, whisking in one scoop at a time, to make a thick batter.
Pour into the greased pan and optionally add slivered almonds on top. Cover the pan with tin foil to avoid burning the surface.
Bake the cake for about 40 minutes or until a skewer inserted in the center of the cake comes out almost clean. Allow the cake to cool before removing from the pan. Optionally garnish with powdered Erythritol and slice into 12 pieces.
