Start by adding 2 cups of vanilla ice cream, 1 cup of milk, 1 teaspoon of vanilla extract, and 1 teaspoon of black gel food coloring to a blender. Blend on medium speed for about 30 seconds until the mixture is smooth and creamy. If the color isn’t dark enough, add a few more drops of black gel food coloring until the desired spooky hue is achieved.

Taste your Spooky Black Halloween Milkshake and decide if you want to adjust its thickness. For a creamier shake, add in a little more ice cream, blending for an additional 15-20 seconds. If it's too thick, pour in an extra splash of milk and blend again until you achieve the desired consistency.

Chill your serving glasses by placing them in the freezer for about 5-10 minutes. Chilled glasses help keep your milkshake cold longer.

Pour the milkshake evenly into the prepared glasses, filling them about ¾ full. Top each milkshake generously with whipped cream.

Sprinkle black and orange sprinkles over the whipped cream. Add a layer of crushed chocolate cookies and decorate with Halloween-themed candies.

Insert black straws or spoons into each milkshake to complete the theme. Serve immediately.
