Pre heat oven 180 degrees.
Remove eggs and butter from the fridge to bring them to room temperature.
Prepare a 23 cm (8 in) round cake pan, greased with butter and with parchment paper, also greased on the bottom.
Mix the almond flour, cornstarch, crushed biscuits, salt and set aside.
Melt the butter and chocolate in microwave on medium power for 1 or 2 minutes or until chocolate is melted. Be careful not to burn the chocolate. Reserve.
Beat eggs with a wire whisk and add sugar and beat well. Add the melted chocolate and butter. Beat until combined and shiny.
Add the flour and stir until everything is mixed. Don't over mix.
Place in the prepared pan. Bake at 180 degrees for 35-45 minutes. Depending on your oven it may take longer, use the toothpick test. Brownie is ready when the toothpick comes out with some crumbs stuck to it.
When cool, unmold and turn right side up. Cover with apricot jam and decorate with reserved cookies.
