Sometimes you just need a creamy chocolatey milkshake that actually fits into your healthy routine. This Ninja Creami Protein Milkshake has become my go-to treat whenever I crave something dessert-like but want to keep it plant-based satisfying and loaded with good-for-you ingredients.

After finding myself reaching for desserts that left me a bit sluggish I put this recipe together to have a chocolate fix that powers me up after my workouts. Now my partner makes his own version every weekend and swears it makes breakfast feel like a treat.

Ingredients

  • Oat milk: gives a creamy base that is naturally sweet. Look for unsweetened oat milk that lists water and oats as the first ingredients for best results.
  • Peanut butter: adds healthy fats and thickness. Natural peanut butter with no added oils or sugars works best.
  • Maple syrup: brings in a subtle rich sweetness. Use pure maple syrup for its clean flavor.
  • Vanilla extract: boosts that milkshake flavor. Opt for pure vanilla extract rather than imitation.
  • Vanilla protein powder: delivers the protein kick you want. Choose a blend that is smooth and not too chalky.
  • Chocolate syrup: flavors the shake and makes it taste like dessert. Pick a sugar free or low sugar option for a lighter touch.

Instructions

Whisk Together the Ice Cream Base:
In a large bowl combine oat milk peanut butter maple syrup vanilla extract and protein powder. Whisk until everything is thoroughly mixed and no clumps remain. This ensures a smooth creamy texture in the finished shake.
Freeze the Mixture:
Pour the blended base into your Ninja Creami pint container. Make sure not to fill above the max line. Cover with a lid and place the container in your freezer for at least 12 hours. This long freeze is key for the Ninja Creami to do its job.
Blend into a Milkshake:
Once fully frozen remove the lid. Add half a cup of oat milk and chocolate syrup directly into the pint. Place the pint in your Ninja Creami and select the milkshake preset. This setting will whip it all together for that classic milkshake consistency.
Respin for Extra Creaminess:
Open the pint and give everything a gentle stir especially to scrape down the sides. Run the milkshake setting a second time for a smoother more evenly creamy texture. The shake should be thick but will loosen up quickly.
Serve or Store:
Pour the milkshake into glasses or enjoy straight from the pint. If you want to save some for later pop the pint back in the freezer with the lid on. To reblend after freezing let it sit out for 10 to 15 minutes add another tablespoon of oat milk and use the milkshake setting again.

Honestly peanut butter makes everything better in my world. The first time I made this I let my brother pick the add ins and we got a little wild with toppings. Now it is a family competition for the best flavor twist we can come up with.

Storage Tips

This milkshake stores perfectly in a Ninja Creami pint for up to a week. Just cover and freeze. When you want a shake let it thaw a bit on the counter before spinning again for that straight from the machine texture.

Ingredient Substitutions

Feel free to switch out oat milk for soy milk to boost the protein a little more. Almond milk or cashew milk will work but the texture is a bit lighter. Almond butter or sunflower seed butter can take the place of peanut butter if you need a different nut free option.

Serving Suggestions

Try topping with a drizzle of extra chocolate syrup a sprinkle of cocoa nibs or even a dollop of coconut whipped cream. You can also mix in mini chocolate chips or chopped nuts for extra crunch.

Cultural Historical Context

Milkshakes became big in America as classic diner treats. Now with tools like the Ninja Creami you can enjoy those same frosty textures in a totally plant powered high protein way.

Seasonal Adaptations

Swap chocolate syrup for strawberry or raspberry puree for a fresh summer twist Blend with pumpkin spice protein powder and a dash of cinnamon as the weather cools Top with fresh berries or peaches for a fruity spring vibe
