When the chocolate/nut butter mix is cool enough, whisk in the eggs, sugar, and vanilla.
In a small bowl, mix the almond meal, flour, cocoa powder, and salt. Add this mixture to the chocolate mixture. Stir to combine.
Press the mixture into a greased 8x8" pan. Bake in an oven at 350F. I like my brownies exceptionally soft and fudgy, so I pulled them out at about 15 minutes, when the edges were just starting to look cooked.
