BROWNIE MIX INGREDIENTS
½ cup butter
1 tbsp almond milk
I made the brownie mix with butter instead of coconut oil and 2 eggs instead of 1, then I poured it into a parchment lined 10x15 cookie sheet and baked for 20-25min. Once cooked I removed from the oven and allowed the brownies to cool completely before cutting and filling with ice cream.
