Ingredients You’ll Need

This recipe’s magic really lies in balancing creamy oat milk with cozy peanut butter and protein powder that blends smooth every time. Pick quality oat milk (unsweetened if you prefer less sugar), and don’t skimp on the maple syrup—it’s a flavorful but gentle sweetener that plays so nicely here.

• Oat Milk: Creamy and naturally sweet, oat milk is what makes this milkshake smooth and dairy-free.
• Peanut Butter: Choose your favorite style—creamy works best for blending and adds a nutty richness.
• Maple Syrup: Provides natural sweetness and deep caramel notes; pure maple syrup is ideal.
• Vanilla Extract: Just a teaspoon amps flavor without extra sugar or calories.
• Vanilla Protein Powder: I recommend a good quality plant-based or whey protein powder—it adds nutrition and a lovely vanilla note.
• Chocolate Syrup: Use lower-sugar or sugar-free versions to keep sweetness in check but still indulge your chocolate cravings.

Variations

One of my favorite things about this Creamy Protein Milkshake with Oat Milk Recipe is how easy it is to customize. I often switch up the flavors or protein sources depending on my mood or what I have on hand. Feel free to make it your own!

• Flavor Swaps: I’ve swapped peanut butter for almond or cashew butter for a different nutty twist—both work beautifully!
• Dairy-Free Protein: If you’re plant-based, pea or rice protein powder blends smoothly and tastes great.
• Sweetener Adjustments: Sometimes I use honey or agave instead of maple syrup, especially when I want a subtler sweetness.
• Oat Milk Alternatives: Soy milk brings a higher protein punch and still keeps things creamy if you want a protein boost without adding powders.

How to Make Creamy Protein Milkshake with Oat Milk Recipe

Step 1: Whisk Your Ice Cream Base Ingredients

This step is crucial for a smooth shake—mix 2 cups oat milk, 1/4 cup peanut butter, 1/4 cup maple syrup, 1 teaspoon vanilla extract, and 1/4 cup vanilla protein powder in a bowl. I like to whisk this vigorously so the peanut butter fully incorporates without lumps. If you’re anything like me, a smooth base makes the final shake even more luscious!

Step 2: Freeze in Your Ninja Creami Container

Pour that luscious mixture into your Ninja Creami pint container and freeze for 12 to 24 hours. Don’t skip this step—that solid freezing is key to achieving the creamy texture we’re aiming for. I usually freeze mine overnight, which fits perfectly into my morning prep routine.

Step 3: Spin Into a Shake with Add-Ins

Once frozen, remove the lid and add 1/2 cup oat milk plus 2-3 tablespoons chocolate syrup. Then, spin it on the milkshake setting. Here’s a little trick I discovered: stir it once after the first spin, then spin again. This double spin action makes the texture thick yet creamy—just like a frappe, but way healthier.

Step 4: Serve and Enjoy

Your shake will be thick, almost like soft serve, but it melts quickly into a silky milkshake as you sip. I like to let it sit at room temperature for 10-15 minutes before serving if I want a slightly thinner consistency, adding a splash more oat milk if needed.

How to Serve Creamy Protein Milkshake with Oat Milk Recipe

Garnishes

I love adding a sprinkle of crushed peanuts or cacao nibs on top—it adds a satisfying crunch and an extra layer of flavor. Whipped coconut cream is also a fun touch for a fancy brunch shake, and a drizzle of extra chocolate syrup never hurts!

Side Dishes

This shake pairs beautifully with a light snack like homemade granola bars or fresh fruit slices. When I’m feeling indulgent, a warm oat muffin completes the meal perfectly, balancing that cold creamy shake with something soft and crumbly.

Creative Ways to Present

For a special occasion, I like serving this protein milkshake in vintage milk bottles or mason jars topped with colorful paper straws. Adding edible flowers or a dusting of cinnamon can also elevate the whole experience—perfect for impressing your guests without extra fuss.

Make Ahead and Storage

Storing Leftovers

Leftovers can be returned to your Ninja Creami pint container and stored in the freezer for up to a week. I label mine with dates because sometimes I get a little overzealous making this shake—it’s that good!

Freezing

Freezing works like a charm here, provided you keep the shake tightly sealed. I recommend freezing in single servings if you want easy grab-and-go options; it reheats quickly without losing texture thanks to the oat milk base.

Reheating

To enjoy leftovers, let the shake sit at room temperature for 10-15 minutes, add a splash of oat milk, and give it a quick spin again if you’re using the Ninja Creami. If you don’t have the machine handy, blending in a high-speed blender achieves a similar result.
