Preheat oven at 350-degrees. Line an 8x8 or 9x9 pan with foil and apply butter or nonstick spray.
In the microwave, melt the butter in a medium-sized bowl. Stir in the sugar, salt, vanilla, cocoa, and eggs. Add in the almond flour and baking powder. Pour batter into the ready pan.
Bake for 33 to 38 minutes, until the top is set and the middle just passes the toothpick test. Let cool, then cut into blocks. Store at room temperature in a sealed container or freeze for later enjoyment.
