Pre-heat oven to 350℉.
In a large mixing bowl, add melted cannabutter, sugar, eggs and vanilla extract. Whisk until well combined and smooth.
Add flour, cacao powder, salt into the same bowl. Stir everything together to make a thick batter.
Line a 8-inch square cake pan with parchment paper. Grease the sides with oil. Transfer the brownie batter into the pan. Then level and smooth out the surface. You can decorate the brownie top with chocolate chips but that’s completely optional.
Bake the brownie at 350℉ for 30 minutes. Remove the brownie from the pan to a cutting board. Cut the slab into 25 (5x5) even pieces.
