My Experience Making This Recipe
The first time I made this, I was honestly skeptical that a homemade version could match the novelty of the original. But blending vanilla ice cream with blackberries and a splash of milk created something almost better, because I could taste actual fruit instead of artificial flavoring.
My kids went absolutely silent while drinking theirs, which is basically a five-star review in parenting terms. The color shift from deep purple when cold to a slightly lighter shade as it warmed up on the counter felt like a little magic trick each time.
I’ve now made this shake at least a dozen times, and it’s become a go-to when someone asks for something special but I don’t want to spend hours in the kitchen. It’s the kind of recipe that feels fancier than it actually is.

Ingredients for Grimace Shake
- Vanilla ice cream: 2 cups, packed
- Fresh or frozen blackberries: 1 cup
- Whole milk: 1/2 cup
- Sweetened condensed milk: 2 tablespoons
- Vanilla extract: 1/4 teaspoon
Ingredient Notes and Substitutions
- Vanilla ice cream serves as the creamy base that gives this shake its thick, indulgent texture. If you don’t have vanilla, use any neutral-flavored ice cream like French vanilla or plain, though the flavor profile will shift slightly.
- Blackberries create that signature deep purple color and tart-sweet flavor that defines the shake. Frozen blackberries work just as well as fresh ones and are often more convenient; fresh blueberries alone won’t achieve the same color, but you can use half blackberries and half blueberries for a similar effect.
- Whole milk keeps the shake drinkable while maintaining creaminess. You can substitute 2% milk if you want a slightly lighter version, or use almond milk for dairy-free option, though the texture will be thinner.
- Sweetened condensed milk adds richness and intensifies the purple hue naturally. Regular sugar mixed with a splash of heavy cream mimics this effect, but you’ll need to increase the amount to about 3 tablespoons total sugar.
- Vanilla extract brightens the flavor and prevents the shake from tasting flat. Almond extract can replace it in a pinch, though it will add a different taste dimension.
How to Make Grimace Shake
Step 1: Gather Your Ingredients
Pull your ice cream from the freezer about two minutes before blending so it softens just slightly and blends more easily. This tiny pause makes a huge difference in whether your blender works smoothly or labors.
Step 2: Add Ice Cream to the Blender
Scoop all two cups of vanilla ice cream into your blender first. Putting the heaviest, most stable ingredient in first prevents the blender from splattering when you turn it on.
Step 3: Pour in the Milk
Add the half cup of whole milk over the ice cream. The milk acts as a liquid that helps the blender break down the ice cream without adding extra ingredients.
Step 4: Add Blackberries
Toss in all one cup of blackberries, whether frozen or fresh. If using frozen berries, you can blend them directly from the freezer; they’ll help keep the shake cold and thick.
Step 5: Mix in Sweetened Condensed Milk
Drizzle the two tablespoons of sweetened condensed milk into the blender. This ingredient doesn’t just sweeten; it deepens the purple color and creates a richer mouthfeel.
Step 6: Add Vanilla Extract
Pour in the quarter teaspoon of vanilla extract. This small amount lifts the overall flavor and prevents the shake from tasting one-dimensional.
Step 7: Blend Until Smooth
Cover your blender and blend on high speed for about 30 to 45 seconds, stopping halfway to scrape down the sides with a spatula if needed. You’re looking for a completely smooth consistency with no chunks of ice cream or whole berries visible.
Step 8: Divide and Serve Immediately
Pour the shake evenly into two tall glasses and serve right away with straws. The shake is best enjoyed while thick and cold, before the ice cream starts melting.
Pro Tip: Chill your glasses in the freezer for five minutes before pouring if you want the shake to stay cold longer and taste even more refreshing.
Tips for the Best Grimace Shake
- Use frozen blackberries instead of fresh for a thicker shake that stays cold longer without needing extra ice. Frozen fruit also means you can make this year-round without worrying about berry season.
- Don’t skip the sweetened condensed milk; it’s what gives this shake that signature deep purple hue and glossy appearance. Regular sugar won’t achieve the same visual effect.
- If your shake turns out too thin, add another half cup of ice cream and reblend for 15 seconds. If it’s too thick to drink through a straw, add a tablespoon of milk at a time until it reaches your preferred consistency.
- Blend for the shortest time possible to avoid over-mixing, which can make the shake icy and separate. Thirty to 45 seconds is usually perfect.
- Serve immediately after blending for the best texture and color; letting it sit makes it separate and watery.
- If you’re making this for a crowd, blend in batches rather than trying to double the recipe in one go, which can overwhelm your blender motor.
Common Mistakes to Avoid
- Using only blueberries instead of blackberries results in a blue shake rather than that iconic purple color. Blackberries have a deeper pigment that creates the true Grimace shade.
- Adding regular milk instead of the sweetened condensed milk makes the shake too thin and loses the creamy, indulgent quality. The condensed milk is not negotiable for texture and color.
- Blending for too long causes the shake to separate and become icy rather than creamy. Long blending also oxidizes the berries and dulls the color.
- Using melted or overly soft ice cream produces a thin, soupy shake instead of the thick, luxurious texture you’re after. Keep your ice cream frozen solid until the moment you blend.
- Forgetting the vanilla extract makes the shake taste flat and one-dimensional, like just frozen fruit and cream. This small amount is crucial for complexity.
Serving Suggestions
This shake works perfectly as a standalone dessert, but you can easily turn it into a full treat by pairing it with something salty or crispy. The creamy berry flavor plays beautifully against contrasting textures.
- Serve with homemade or store-bought sugar cookies for dipping
- Pair with a warm chocolate brownie for a contrasting temperature experience
- Offer alongside crispy waffle fries or potato chips for a sweet-salty combination
- Present with a small cheese board for a sophisticated dessert pairing
- Accompany with mini donuts or churros for a nostalgia-driven treat
Variations to Try
- Berry Blast: Swap half the blackberries for fresh raspberries or strawberries for a softer purple with mixed berry complexity. The flavor becomes brighter and more tart.
- Chocolate Grimace: Add two tablespoons of chocolate syrup or cocoa powder to create a deep purple-brown shake with hints of chocolate. This version tastes like a berry-chocolate hybrid.
- Protein Power: Blend in half a scoop of vanilla protein powder for added nutrition without dramatically changing the flavor or texture. This makes the shake more filling.
- Lactose-Free: Substitute dairy milk with oat milk and use dairy-free vanilla ice cream for a fully dairy-free version. The taste stays nearly identical while becoming accessible to more people.
- Boozy Version: For adults, add one tablespoon of berry vodka or chambord liqueur to create an after-dinner shake. Keep the amount small so the alcohol flavor doesn’t overpower the fruit.
Dietary Adaptations
- Gluten-free: This shake is naturally gluten-free as written; just confirm your ice cream and other ingredients don’t contain hidden gluten, as some brands add it as a thickener.
- Dairy-free: Use coconut milk or oat milk instead of whole milk, and swap vanilla ice cream for a dairy-free frozen dessert made from coconut or cashew cream.
- Vegan: Choose plant-based vanilla ice cream and use agave syrup instead of sweetened condensed milk, though you may lose some of the purple depth.
- Low-carb or keto: Substitute regular ice cream with keto-friendly vanilla ice cream and use monk fruit sweetener instead of sweetened condensed milk to keep carbs minimal while maintaining sweetness.
Storage and Reheating
Refrigerator
This shake is best consumed immediately after blending, but you can store leftovers in an airtight container for up to two hours. The texture will separate and become watery as the ice cream melts.
- Transfer to a sealed container right after blending
- Store on the coldest shelf of your fridge
- Stir vigorously before serving again
Freezer
You can freeze the shake mixture in popsicle molds or small containers for a frozen treat that lasts up to one week. This transforms the shake into something like a blackberry ice cream pop.
- Pour into popsicle molds and freeze for at least four hours
- Store frozen in an airtight container for up to seven days
- Let sit at room temperature for two minutes before eating if frozen solid
Reheating
This shake doesn’t need reheating since it’s served cold. If separation occurs, simply reblend for 15 seconds with a splash of fresh milk.
- Don’t use heat; reblend instead if consistency changes
- Add fresh milk one tablespoon at a time to restore creaminess

Frequently Asked Questions
Can I Make This Shake Without Blackberries?
You can, but the color and flavor profile change significantly. A combination of blueberries and a tablespoon of raspberry jam gets you closer to the original purple shade, though it won’t be identical.
How Do I Make the Shake Thicker Without Adding More Ice Cream?
Use frozen blackberries instead of fresh ones, and reduce the milk to one quarter cup instead of one half cup. You can also add a few ice cubes right before blending, though this dilutes flavor slightly as they melt.
Is This Shake Actually Purple Without Food Coloring?
Yes, the blackberries and sweetened condensed milk create a naturally deep purple color that’s remarkably vibrant. The pigments in blackberries are strong enough that you need no artificial dyes.
Can I Prepare the Ingredients Ahead of Time?
You can measure out the blackberries and milk ahead, but don’t blend until ready to serve. Ice cream must stay frozen until the last moment to maintain the proper thick texture.
What’s the Difference Between This and a Regular Berry Smoothie?
This shake uses ice cream as the primary base, making it dessert-like and indulgent. A smoothie typically uses yogurt or milk with less fat and is positioned as a healthier drink option.
Can I Use Sherbet or Sorbet Instead of Ice Cream?
Sherbet works and keeps the shake purple, though it’s less creamy than traditional ice cream. Sorbet alone makes the shake too icy and thin; you’d need to add cream or condensed milk to get the right texture.
