# Grimace Shake

A vivid purple vanilla-berry milkshake with a whipped cream crown — the viral McDonald's birthday shake, made at home in minutes.

_Beverage · American_

Prep: 5 min · Total: 5 min · Yields: 2 servings

## Ingredients

- 3 cups vanilla ice cream (about 4 large scoops)
- ½ cup whole milk
- ½ cup frozen blueberries
- ¼ cup frozen blackberries
- 1 tsp vanilla extract
- ½ cup heavy whipping cream (for topping)
- 1 tbsp powdered sugar (for whipped cream)
- 2 tbsp purple or violet sprinkles (optional, for garnish)

## Instructions

1. Chill two tall glasses in the freezer for at least 5 minutes while you prep — a cold glass keeps the shake from melting too fast.
2. Add the 0.5 cup whole milk to the blender first; this protects the blade and helps the shake blend smoothly.
3. Add the 3 cups vanilla ice cream, 0.5 cup frozen blueberries, 0.25 cup frozen blackberries, and 1 tsp vanilla extract to the blender.
4. Blend on high for 20–30 seconds until completely smooth and uniformly deep purple. Stop and scrape down the sides if needed, then blend for another 5 seconds.
5. Check consistency: the shake should be thick enough to mound slightly when poured. If too thick, add milk 1 tbsp at a time and pulse; if too thin, add another scoop of ice cream and blend briefly.
6. In a separate chilled bowl, whip the 0.5 cup heavy whipping cream and 1 tbsp powdered sugar with a hand mixer on medium-high until stiff peaks form, about 2 minutes.
7. Pour the shake evenly into the two chilled glasses, leaving about 1 inch of headspace for the whipped cream.
8. Pipe or spoon the whipped cream generously on top of each shake, then finish with the 2 tbsp purple or violet sprinkles if using. Serve immediately with a wide straw.

## Tip

> Frozen berries are non-negotiable here — they thicken the shake and deepen the purple color without watering it down the way fresh berries would. Blueberries alone skew blue-grey; the blackberries pull it into true purple.
