Cook's Note: If the pie is not streusel-topped, add 1 tablespoon of brown sugar into the blender with the pie.
Combine the brandy, cinnamon liqueur and pie in a blender and blend on high speed until very smooth, 5 to 7 minutes. Pour into 2 up glasses, sprinkle the cinnamon on top and garnish with a wedge of cheddar cheese on the rim, if using. Apologize to the rest of the pie for blending that 1 slice of pie. Continue drinking.
