Brownies
Soak raw cashews and walnuts overnight with a pinch of salt (or soak in hot water for 2 hours). Drain and rinse.
Soak the medjool dates in hot water for 10 minutes if they are hard and dry. A plum and sticky/gooey texture is preferred.
In a food processor, pulse together raw walnuts, dates (pits removed) until gooey and smooth.
Add cacao powder and a pinch of salt. Blend until smooth and dough-y.
Layer the 9 cookies on top of the crust. then layer the brownie dough on top. Smooth it out across the the whole pan.
Chocolate Frosting
In a microwave-safe bowl melt chocolate and coconut oil.
Pour it over the brownie layer and place it in the freezer (3 hours) to allow the frosting to set before cutting.
Notes
*Soaking the nuts and medjool dates can make the texture more gooey and smooth.
