Preheat oven to 350 F and line the bottom of an 8x8" pan with parchment paper.

For the crust, mix together melted butter and cannabis butter and sugar. Add the flour and salt and mix until just combined.

Press the dough evenly into the bottom of the prepared dish. Bake for 10 minutes. Remove from oven and set aside.

For the lemon filling, mix the lemon zest and sugar in a large mixing bowl. Add the lemon juice, flour, and baking powder. Then, mix in the eggs. Pour lemon mixture over the crust.

Bake for approximately 25 minutes or until the filling has set. Remove from oven and allow to cool completely before dusting with powdered sugar.
