Ingredients You’ll Need

Every ingredient here works together to create that classic peanut butter milkshake vibe, but with a health-conscious twist. I love using oat milk because it’s naturally creamy, but I’ll share some swaps later that also work great!

• Oat Milk: Makes the shake creamy and dairy-free; also provides a smooth texture in the ice cream base and shake add-ins.
• Peanut Butter: Go for natural peanut butter with smooth or crunchy texture depending on your preference—it adds both flavor and protein.
• Maple Syrup: Natural sweetener that blends perfectly with peanut butter’s earthiness.
• Vanilla Extract: Just a teaspoon brightens the flavor and balances all the other ingredients.
• Vanilla Protein Powder: I recommend a high-quality whey or plant-based powder to boost your protein intake without overpowering the taste.
• Chocolate Syrup: Choose a lower sugar or sugar-free option to keep the shake healthy but still satisfy your chocolate cravings.

Variations

One of the things I love about this Protein Peanut Butter Milkshake Recipe is how easy it is to customize. Depending on your tastes or dietary needs, you can switch things up and still get great results.

• Swap Oat Milk for Soy Milk: I discovered this trick when I needed a higher protein boost—soy milk doesn’t compromise creaminess but adds extra nourishment.
• Add a Frozen Banana: If you want it thicker and with natural sweetness, frozen banana blends beautifully and makes it more smoothie-like.
• Use Peanut Butter Powder: For a lighter version, powdered peanut butter still delivers that peanut flavor with fewer calories and less fat.
• Dairy Version: If dairy isn’t an issue, swap oat milk for whole milk or half-and-half, and you’ll get an ultra-rich experience.

How to Make Protein Peanut Butter Milkshake Recipe

Step 1: Whisk Together the Ice Cream Base Ingredients

Start by mixing the oat milk, peanut butter, maple syrup, vanilla extract, and vanilla protein powder in a bowl until everything is smooth and fully combined. I like to use a whisk here because it breaks up any clumps in the protein powder. It’ll look like a rich, creamy batter — delicious already!

Step 2: Freeze the Mixture in the Ninja Creami Pint

Pour your mixture into the pint container that came with your Ninja Creami, leveling it out so it freezes evenly. Freeze it for 12 to 24 hours, depending on your schedule. I usually aim for the full 24 hours so the texture is perfect and scoopable.

Step 3: Add Milk and Chocolate Syrup — Then Spin!

After freezing, remove the lid and add the extra oat milk along with 2-3 tablespoons of your favorite chocolate syrup. Place the lid back on and spin it on the milkshake setting of your Ninja Creami. Once it’s done, give it a good stir and spin it again to get that ultra-creamy consistency. It will be thick but melts quickly into a thick milkshake texture that’s just heavenly.

How to Serve Protein Peanut Butter Milkshake Recipe

Garnishes

I love topping this shake with a sprinkle of crushed peanuts or a drizzle of extra chocolate syrup for visual appeal and a little textural crunch. If you’re feeling extra, a dollop of whipped cream never disappoints—I’ve even added a pinch of cinnamon on occasion for a warm note that pairs well with peanut butter.

Side Dishes

Since this shake is pretty substantial on its own, I usually keep it simple with some fresh fruit on the side—apple slices or banana chunks are my go-to. But if you want a heartier snack, try pairing it with a small oat-based cookie or granola bar for some crunch and fuel.

Creative Ways to Present

For special occasions, I’ve poured this shake into tall glasses with a sugared rim (just dip the rim in chocolate syrup then crushed peanuts). Adding a fun reusable straw and a few mini peanut butter cups on the side makes it feel super festive and gourmet—you’ll impress any guests with minimal effort!

Make Ahead and Storage

Storing Leftovers

I like to store any leftover milkshake in the Ninja Creami pint container sealed tightly and popped back into the freezer. That way, it keeps fresh and you can enjoy a second round whenever you want. Just plan ahead — it’s best within a week.

Freezing

Freezing works beautifully with this recipe because the base is made to freeze hard before spinning. I’ve frozen leftovers for a few days before, and after thawing and re-spinning, it tastes just as good as freshly made. Perfect for batch prep!

Reheating

This isn’t a milkshake you reheat—instead, I recommend letting any frozen leftovers soften at room temperature for about 10-15 minutes, then add a tablespoon of milk and spin it again in the Ninja Creami. This quick step brings back the creamy milkshake consistency like magic.
