5-Minute Brownie Batter Milkshake

This brownie batter milkshake tastes exactly like scraping the bowl after mixing brownies, but in a thick, sippable form. It’s the kind of shake that turns a bad day around real quick.

It takes five minutes from blender to glass and tastes like a cross between a chocolate milkshake and actual brownie batter, with little fudgy flecks that make it extra special.

What Makes This Brownie Batter Milkshake So Good

The brownie mix does all the heavy lifting here. Just a quarter cup of dry mix gives that unmistakable batter flavor and creates tiny, chewy bits that melt into the shake as you sip.

It’s ridiculously creamy from the vanilla ice cream and just sweet enough. No baking, no waiting, just a big cold glass of pure batter bliss.

Ingredients

• 2 cups vanilla ice cream: use a good quality full-fat ice cream for the thickest texture.
• 1/2 cup whole milk: plus more if needed.
• 1/4 cup dry brownie mix: from a boxed mix, heat-treated if you like (see FAQ).
• 2 tbsp chocolate syrup: optional, for extra richness.
• 1/2 tsp vanilla extract
• Pinch of salt

Variations / Substitutions

• Dairy-free: use your favorite non-dairy vanilla ice cream and oat or almond milk.
• Peanut butter swirl: add 1 tbsp peanut butter before blending for a nutty twist.
• Mocha version: blend in 1 tsp instant espresso powder and reduce the chocolate syrup slightly.
• Extra fudgy: swap the chocolate syrup for 2 tbsp hot fudge for a thicker, richer shake.

If you’d rather bake, our Classic Fudgy Brownies give you that same rich chocolate hit.

How to Make a Brownie Batter Milkshake

Step 1: Blend the Milkshake

Add the 2 cups ice cream, 1/2 cup milk, 1/4 cup brownie mix, 2 tbsp chocolate syrup, 1/2 tsp vanilla, and a pinch of salt to a blender. If you are concerned about raw flour, microwave the dry brownie mix in a bowl for 1 minute, stirring every 15 seconds, then let it cool before adding. Blend on high for about 30 seconds, until completely smooth and thick.

Step 2: Adjust the Consistency

Check the thickness. If the milkshake is too thick to blend easily, add another splash of milk, 1 tbsp at a time, and pulse until it reaches a pourable but still very thick consistency. You want it thick enough to support a straw but not so stiff it won’t go up.

Step 3: Pour and Top

Pour the milkshake straight into a tall chilled glass. Top with a generous swirl of whipped cream, a drizzle of chocolate syrup, and a few sprinkles if you are feeling festive. Serve right away while it’s ice cold.

Tips for the Best Brownie Batter Milkshake

• Chill your glass in the freezer for 5 minutes before pouring to keep the shake thick longer.
• For a less sweet shake, leave out the chocolate syrup and add 1 tbsp unsweetened cocoa powder instead.
• The brownie mix particles settle as you drink, so give it a stir every few sips to keep the batter flavor even.
• If you want a boozy adult version, add 1 oz bourbon or coffee liqueur before blending. It cuts the sweetness nicely.

Frequently Asked Questions

Is it safe to drink raw brownie mix?

Most boxed brownie mixes contain raw flour, which can harbor bacteria. To be completely safe, microwave the dry mix for 1 minute, stirring every 15 seconds, and let it cool before using.

Can I use homemade brownie batter?

It is trickier because most recipes include raw eggs and flour. For a safe version, make an edible brownie batter using heat-treated flour and no eggs, then blend it in.

Why did my milkshake turn out thin?

Usually it’s because the ice cream was too soft or you used too much milk. Make sure your ice cream is fully frozen and add the milk slowly, a splash at a time.

What is the difference between this and a chocolate milkshake?

The dry brownie mix adds a distinct, slightly fudgy batter flavor and tiny chewy flecks you don’t get from just chocolate syrup or cocoa powder.
