Preheat oven to 350°F (175°C). Line or grease an 8-inch round cake pan.

In a bowl, mix almond flour, sweetener, baking powder, and salt.

In another bowl, whisk eggs, then mix in melted butter, almond milk, and vanilla.

Combine wet and dry ingredients and stir until smooth.

Pour batter into prepared pan and level the surface.

Bake for 25 minutes or until golden and a toothpick comes out clean.

Let cool, then top with whipped cream and sliced almonds.
