Copycat Culver’s Concrete Mixer Recipe: Easy Creamy Frozen Treat

Copycat Culver’s Concrete Mixer® (At-Home Version)

If you’ve ever rolled through the Culver’s drive-thru and ordered a thick, creamy Concrete Mixer®, you know it’s not just any milkshake. It’s richer, thicker, and packed with mix-ins in every bite. Today I’m sharing an easy copycat Culver’s Concrete Mixer® recipe you can make at home with just a few ingredients and a basic blender. No fancy equipment. No weird ingredients. Just cold, creamy goodness in a cup.

About Culver’s & Their Famous Concrete Mixer®

Culver’s is a Midwestern fast-food chain that’s become famous for its ButterBurgers and its extra-rich frozen custard. If you’ve never tried it, frozen custard is like ice cream’s smoother, silkier cousin — it’s made with egg yolks, so it feels almost velvety on your tongue. Their Concrete Mixer® (a registered menu item of Culver’s) is a super-thick custard treat blended with all kinds of mix-ins:
  • Crushed cookies
  • Brownies and cake pieces
  • Chocolate, caramel, and peanut butter swirls
  • Fruits like strawberries or raspberries
The texture is so thick you practically need a spoon. It’s cold, creamy, sweet, and loaded with chunks in every bite. The kind of treat you eat slowly, because it doesn’t melt right away. This recipe is my homemade interpretation of that experience. It’s not the official Culver’s recipe, but it aims to capture that same thick, rich, spoonable custard dessert you crave after a summer road trip or a long day at work.

What Makes a Concrete Mixer®-Style Treat Different?

If you’ve made milkshakes at home, you might be wondering: what’s the big deal? Isn’t it just ice cream and milk? Not quite. A Concrete Mixer–style dessert is:
  • Thicker – more spoonable than drinkable
  • Richer – thanks to egg yolk–based custard or super-premium ice cream
  • Loaded with mix-ins – every scoop has texture and flavor
Think of it like this: A regular milkshake is something you sip. A Concrete Mixer®-style treat is something you dig into. Our copycat version uses either store-bought vanilla frozen custard (if you can find it) or a very rich vanilla ice cream plus a quick “custard hack” to get closer to that dense, creamy texture.

Copycat Culver’s Concrete Mixer® Recipe

This base recipe makes a classic vanilla Concrete Mixer–style treat with Oreo®-style cookies. You can easily swap in your favorite mix-ins (see ideas below).

Recipe Overview

  • Serving size: 2 large servings (or 3 smaller ones)
  • Prep time: 10–15 minutes
  • Chill time (optional for extra thickness): 20–30 minutes
  • Difficulty: Easy
  • Equipment: Blender or food processor, mixing bowl, spoon

Ingredients

For the custard-style base:
  • 3 cups very cold vanilla frozen custard (preferred) or super-premium vanilla ice cream
  • 1/4 cup heavy cream (for richness and smooth blending)
  • 1 egg yolk, pasteurized* (optional but helps mimic frozen custard)
  • 1 teaspoon pure vanilla extract
  • Pinch of salt (brings out flavor)
For the Oreo®-style mix-in:
  • 6–8 chocolate sandwich cookies, roughly crushed
Optional toppings & variations: *Food safety note: Use pasteurized eggs or egg products whenever using raw egg yolks, especially for children, pregnant people, elderly family members, or anyone with a weakened immune system. If you prefer, you can omit the egg yolk entirely; your treat will still be delicious.

Step-by-Step Instructions

Step 1: Chill Your Gear

For a thicker, more concrete-like texture:
  • Place your serving glasses in the freezer for 10–15 minutes.
  • If your blender pitcher is removable, you can chill that briefly too.
Cold tools help keep everything thick instead of melting into a regular milkshake.

Step 2: Prep the Mix-Ins

  • Place the sandwich cookies in a zip-top bag.
  • Crush them with a rolling pin, skillet, or your hands until you have a mix of small chunks and crumbs.
You want pieces big enough to bite into, not fine powder. That texture is part of the “concrete” feel.

Step 3: Make the Custard-Style Base

In your blender, add:
  • Vanilla custard or ice cream
  • Heavy cream
  • Egg yolk (if using, and pasteurized)
  • Vanilla extract
  • Pinch of salt
Pulse on low just until everything comes together. You’re not going for a thin shake — you want it thick and scoopable. If it seems too thick to blend:
  • Add 1–2 tablespoons of heavy cream at a time.
  • Pulse again briefly.
Stop blending as soon as it looks smooth but still very dense.

Step 4: Fold In the Mix-Ins

Pour the custard base into a mixing bowl (or leave in the blender pitcher and stir by hand).
  • Add your crushed cookies.
  • Gently fold them in with a spatula or spoon until just combined.
You want visible swirls and chunky bits. Over-mixing will turn your Concrete Mixer®-style treat gray and crumbly-looking instead of speckled and pretty.

Step 5: Adjust the Texture (Optional)

If it’s not as thick as you’d like, try one of these:
  • Spoon the mixture into your chilled glasses and place back in the freezer for 20–30 minutes to firm up.
  • Or, add a little more frozen custard or ice cream and fold it in by hand.
If it’s too thick, let it sit at room temperature for 3–5 minutes, then give it a quick stir.

Step 6: Serve & Customize

Spoon into chilled glasses or bowls. Top with:
  • Extra cookie crumbles
  • A drizzle of chocolate syrup or caramel
  • Whipped cream
Grab a sturdy spoon and dig in. This is a spoon dessert, not a straw dessert.

Concrete Mixer® Flavor Ideas

Once you have the basic method down, you can create your own “menu” at home. Here are some fun combinations:
  • Chocolate Brownie Blast – Use chocolate custard or ice cream, brownie chunks, and hot fudge swirls.
  • Strawberry Cheesecake – Add strawberry sauce, cheesecake chunks, and graham cracker crumbs.
  • Peanut Butter Cup – Vanilla base with chopped peanut butter cups and a swirl of peanut butter.
  • Caramel Pecan Crunch – Vanilla base, caramel sauce, toasted pecans, and a pinch of sea salt.
  • Mint Cookie Crunch – Mint-chocolate-chip ice cream with extra chocolate cookies and chocolate chips.
What flavor combo will you try first?

Nutrition (Approximate Per Serving)

Time-Saving & Equipment Tips

Don’t own a blender? You still have options.
  • Food processor: Works just like a blender for this recipe.
  • Hand-mix method: Let ice cream soften slightly, then mash with a sturdy spoon or potato masher. Add a splash of cream or milk and your mix-ins.
  • Big batch idea: Make a double batch in advance, spread it into a loaf pan, and freeze. Scoop into bowls like “pre-mixed” custard sundaes.
No need for specialized machines — if you can mash and stir, you can make this.

Allergy-Friendly & Special Diet Swaps

Everyone should get a fun frozen treat when possible. Here are some simple adjustments:

Dairy-Free / Vegan Version

  • Use a rich dairy-free ice cream (like coconut milk or oat milk based).
  • Swap heavy cream for full-fat canned coconut milk or barista-style oat milk.
  • Skip the egg yolk.
  • Choose vegan cookies or mix-ins (check labels for dairy and eggs).

Gluten-Free Version

Nut-Free Version

  • Avoid nut-based toppings and candies.
  • Check your ice cream, cookies, and chocolate for “may contain nuts” warnings if that’s a concern for your household.

Lower-Sugar Option

  • Use a no-sugar-added or reduced-sugar ice cream.
  • Choose sugar-free or reduced-sugar cookies and sauces when possible.
  • Add fresh berries (like strawberries or raspberries) or fruit instead of candy.
Always double-check labels, especially if you’re serving someone with severe allergies or medical conditions.

Food Safety Tips

Even though this is a no-cook dessert, there are a few basic safety tips to keep in mind:
  • Egg safety: If you use the egg yolk for a more custard-like texture, make sure it’s from a pasteurized egg or a pasteurized liquid egg product.
  • Keep it cold: Don’t leave dairy-based desserts out at room temperature for more than 2 hours (1 hour if it’s over 90°F).
  • Allergy awareness: Clearly label mix-ins (especially nuts, gluten, and dairy) when serving a group.
