Preheat the oven to 350 F and line an 8x8 baking pan with parchment paper

In a large mixing bowl, combine the tigernut flour, tapioca starch, cocoa powder, and baking soda and mix to combine

Next, stir in the melted coconut oil, maple syrup and chocolate chips

For the gelatin egg (sub 1 regular egg if tolerated) add the water to a small sauce pot and slowly pour over the 1 tbsp gelatin. You don't want any clumps, so lightly mix if needed. Allow the mixture to rest and bloom over 2-3 minutes. Place the pot on the stove and turn in on low heat. Slowly melt the the gelatin and remove from heat. Vigorously whisk the gelatin egg until it becomes frothy. Add the gelatin egg to the mixture immediately and mix to combine.

Evenly spoon the batter into the baking pan and bake for 25 minutes, or until brownies are baked through

Remove from the oven and allow to cool

For the frosting, combine the ingredients and whisk vigorously until the frosting is fluffy

Slice the brownies into 9 slices, and spread the frosting on top
