Ninja Slushie Peanut Butter Cup Protein Milkshake

This creamy, frosty Ninja Slushie Peanut Butter Cup Protein Milkshake blends indulgence and nutrition into a single glass — think rich peanut butter, chocolatey chunks, and a protein boost that keeps you satisfied. It’s an ideal post-workout treat, an afternoon pick-me-up, or a lighter dessert option that still feels decadent.

Why this recipe works:

• The Ninja Slushie (or any high-powered blender) creates a true slush texture that suspends mix-ins for a restaurant-style milkshake.
• Greek yogurt and a scoop of protein powder add creaminess and a protein hit without relying entirely on ice cream.
• Peanut butter and chocolate chips deliver classic peanut butter cup flavor in a more controlled, customizable form.

Ingredients (serves 1 large or 2 small)

• 1 cup unsweetened almond milk (or milk of choice)
• 1/2 cup plain Greek yogurt (for tang and creaminess)
• 1 frozen banana, chopped (adds sweetness and thickness)
• 2 tbsp creamy peanut butter
• 1 scoop chocolate or vanilla protein powder
• 1 tbsp unsweetened cocoa powder (optional for deeper chocolate flavor)
• 1 cup ice (adjust for desired slushiness)
• 2 tbsp mini chocolate chips or chopped dark chocolate
• Pinch of salt
• Optional garnish: whipped cream, extra peanut butter drizzle, a peanut butter cup half

Equipment

• High-powered blender (Ninja Slushie or equivalent recommended for best texture)
• Measuring spoons and cups
• Serving glass

Directions

1. Prep frozen banana and ice so they’re ready to go. For an extra-thick shake, freeze banana slices overnight.
2. In the blender pitcher add almond milk, Greek yogurt, peanut butter, protein powder, cocoa powder (if using), and a pinch of salt.
3. Add frozen banana and ice on top. Secure lid and pulse a few times to break up the solids.
4. Blend on high until the mixture reaches a smooth, slushy consistency. If the shake is too thick, add a splash more milk; if too thin, add a few more ice cubes or another small piece of frozen banana.
5. Stir in the chocolate chips by hand or use a quick low-speed blend to distribute them without completely melting.
6. Pour into a chilled glass and garnish with whipped cream, a drizzle of peanut butter, and a peanut butter cup half if desired.

Variations and swaps

• Vegan: Use plant-based yogurt and a vegan protein powder. Swap honey or whey protein for a plant-based sweetener if needed.
• Lower sugar: Use unflavored protein powder and omit added sweeteners; increase banana for natural sweetness.
• Kid-friendly swap: Turn this into a thicker spoonable shake by using less milk; you can pair it with soft pancakes for a fun breakfast twist — see our kid-friendly healthy protein pancakes for pairing ideas.
• Peanut-free option: Replace peanut butter with almond or sunflower seed butter for allergy-safe alternatives.

Nutrition (approximate per large serving)

• Calories: ~450–550 (varies with protein powder and milk choice)
• Protein: 25–35 g (dependent on protein powder)
• Fat: 18–25 g
• Carbs: 40–60 g (from banana and milk)
  Adjust ingredient amounts to fit your dietary goals (e.g., lower-calorie milks or smaller peanut butter portions).

Tips for best texture

• Use frozen banana and crushed ice for a thick, frosty result.
• Pulse before full blending to prevent motor strain if your blender isn’t a high-powered model.
• Chill the serving glass for an extra-refreshing presentation.
• Add chocolate chips last to keep them from sinking or fully melting into the shake.

Serving suggestions

• Serve with a wide straw and a long spoon so your guests can enjoy the mix-ins.
• Pair with light salty snacks (like pretzels) to balance the sweetness.
• Make it party-friendly by preparing a peanut butter drizzle station and assorted toppings like crushed cookies, chopped nuts, or shredded coconut.

Storage
This shake is best enjoyed immediately. If you must store it, pour into an airtight container and refrigerate for up to 24 hours; expect some separation — simply stir or re-blend before serving.
