Begin by adding 2 cups of vanilla ice cream, 1 cup of milk, 1/2 cup of pumpkin puree, and 1 teaspoon of pumpkin pie spice to a blender. Blend on high speed for about 30-40 seconds until creamy and smooth.

While blending, take 4 serving glasses and sprinkle 1 tablespoon of crushed graham crackers into each glass for added texture.

Once blended, carefully pour the mixture into the prepared glasses, filling them almost to the top.

Top each glass with whipped cream and sprinkle some extra crushed graham crackers and a dash of pumpkin pie spice for decoration.

Insert a straw into each glass and serve immediately for the best texture.
