To prepare the brownie base, add the almond flour, cocoa powder, baking soda, and salt in a large bowl and stir until combined. Add the melted coconut oil, maple syrup, almond butter, water, and vanilla. Stir until well combined. Set in the fridge to chill for about 10 minutes.

Preheat your oven to 325 degrees Fahrenheit and line a 9x9 baking dish with parchment paper. Remove your prepared doughs from the fridge. Evenly pat the brownie mixture into the bottom of your pan. Drop spoonfuls of the cookie mixture randomly on top of the brownie mixture. Pat down slightly, leaving some spaces of the brownie mixture exposed to achieve a marbled effect.

Bake in your preheated oven for 34-36 minutes. Remove from the oven and let cool completely before slicing into 16 bars.
