Preheat oven to 350°. Prepare an 8 x 8” pan with pan spray or line with parchment paper.

Measure granulated erythritol into a small food procesor, blitz until powdered. Add to a mixing bowl, along with Swerve brown, cocoa, almond flour, protein powder, coconut flour, and salt. Mix well to combine.

Add melted butter, beaten eggs, and vanilla, stir until dry ingredients are well incorporated and wet.

Spread batter into prepared pan, Bake for 20 minutes, or until just set.

Brownies are done when knife inserted into center comes out clean.

Let cool completely before frosting.

Whisk together powdered sugar, cocoa, and salt. Add almond milk and vanilla, whisk to form a VERY thick paste.

Heat in the microwave for 15-20 seconds, and whisk again - it should be thick but spreadable.

Spread frosting over cooled brownie, allow to set up before slicing and serving.
