Place flour, baking powder, baking soda, and sugar in the bowl of a food processor and pulse a few times to mix. Add cannabis-infused butter, butter, and shortening and pulse a few times until you have a mixture that resembles coarse crumbs. Spoon into a medium bowl. (Alternately use 2 knives to cut the fat into the dry ingredients.)
Add buttermilk and stir just until the dough holds together. Mix and knead the dough as little as possible in order to keep the biscuits tender.
On lightly floured surface, roll dough into a disc about an inch high and 6-inches in diameter. Use a round cookie cutter or a glass about 2 1/2inches in diameter to cut out 8 biscuits, rerolling dough as necessary. Arrange on a baking sheet that’s been covered with parchment paper.
Brush top of biscuits with melted butter and bake until golden brown, about 15 minutes. Cool on a wire rack for 3 minutes before serving.
Freezer Friendly! Freeze unbaked biscuits in a single layer before moving to a freezer bag. Bake on a parchment-lined baking sheet at 400 degrees F for 5minutes, brush with melted butter and bake until golden brown, about 15 minutes.
