My wife just so happens to be a trained chef and baker, specializing in gluten-free baking so as a celiac I hit the jackpot.

With the baking good supplies sold out at most grocery stores, this recipe can easily be made with some basic ingredients from home, no flour needed.

Recipe:

• 1 ½ cups chocolate (or chunks/chips or a chopped up bar)
• 6 Tbs butter
• ¼ cup sugar (or white, light brown, dark brown, coconut (any))
• 2 eggs
• 2 tsp, vanilla extract
• ¼ cup cocoa (cacao, dutch processed, etc)
• 3 Tbs cornstarch (arrowroot, potato starch or tapioca)
• ¼ tsp sea salt 

Optional:

• Peanut butter chips
• Walnuts
• Coarse sea salt
• Etc - add your flare

Instructions:

• Preheat the oven to 350
• Line a pan (aluminum foil or parchment)
• Combine 1 cup of chocolate chips and butter: melt in the microwave or double boiler: Stir until smooth 
• Stir in sugar and vanilla, mix until smooth
• Whisk eggs in a separate bowl - pour slowly into the chocolate mixture, whisking continuously 
• Add dry ingredients (cocoa, starch, sea salt): stir until combined
• Add ¼ cup of remaining chocolate chips and pour batter into pan
• Top with final ¼ cup of remaining chips and a sprinkle of sea salt (if desired) & and add in any additional ingredients listed as optional above, here.
• Bake 20-25 min (insert a toothpick or fork into the middle of the brownies - for completion)
