Preheat the oven to 350 degrees F. Line an 8x8-inch square baking pan with non-stick foil or parchment
Melt the dark chocolate and butter together in microwave or in a bowl set over simmering water.
In a mixing bowl, beat the eggs with an electric mixer until frothy. Add the brown sugar and beat until smooth. Add the melted chocolate mixture to the egg-sugar mixture a little at a time and beat well.
In a bowl, combine the nut meal, rice flour, salt and baking soda. Add the dry mixture to the chocolate mixture and stir until well mixed. Add the vanilla, beat another half a minute or so. Stir in the chocolate chips. Pour into the lined pan.
Bake on center rack for 33 to 35 minutes, or until the brownies are set. Don't overcook.
Cool on a wire rack; and remove the brownies from the pan by gripping the foil edges. Chill before cutting.
