½cupbittersweet chocolate chips (optional but recommended)
½cupwalnuts, pecans or chopped almonds
Instructions
Preheat oven to 350 degrees F. Grease an 8-inch metal pan or line with foil and grease the foil.
Melt the butter and chocolate together over low heat in a medium size or large saucepan. When melted, add the sugar and vanilla and stir until smooth. Let cool slightly.
Add the eggs and beat or whisk until well blended, then beat in the almond flour, salt (if using) and nuts. Check to make sure the batter is cool, then add the chocolate chips.
Spread batter in pan and bake for about 30 minutes or until top appears set. Diamond recommends 30 to 35 minutes, but it's probably best to err on the side of underbaking these.
Let cool at room temperature (or chill if you are in hurry).
