Why This Recipe Works (Quick Science)
The frozen banana contains natural starches that create a thick, creamy texture when blended. Protein powder adds body and structure to the shake. Peanut butter contains healthy fats that make the milkshake feel rich and smooth. Ice helps create that classic milkshake consistency while keeping everything cold and refreshing.
Recipe and Instructions
Step 1: Add the Ingredients to the Blender
Add 2 cups milk to the Ninja blender pitcher. Add 1 frozen sliced banana, 2 scoops chocolate protein powder, 3 tablespoons creamy peanut butter, 1 tablespoon unsweetened cocoa powder, 1 tablespoon honey, and 1 cup ice cubes.
Step 2: Blend Until Smooth
Secure the lid and blend on high speed for about 45 to 60 seconds until the frozen banana, chocolate protein powder, peanut butter, cocoa powder, honey, milk, and ice cubes become completely smooth and creamy.
Step 3: Pour and Garnish
Pour the blended milkshake evenly into 2 serving glasses. Top with 2 chopped mini peanut butter cups.
