3. When bubbles start forming on surface of the cream, pour over white chocolate and let sit for 2 minutes.
4. Stir until all chocolate is melted and no lumps remain.
5. Chill ganache in fridge for at least 1 hour or until it thickens enough to be spreadable.

4. Add in flour mixture and stir until combined.
5. Turn dough out onto a large piece of plastic wrap and divide dough in half.

Bottom Cookies
