Expert Tips
The peanut butter balls are optional but elevate the shake to a dessert-like treat. If you skip them, the smoothie is still delicious.
This recipe uses collagen powder rather than traditional protein powder; substituting a protein powder is fine but may change flavor and texture. Beef isolate or other neutral powders work well.
Frozen bananas give the smoothie its thick, creamy, ice-cream like texture. If you only have fresh bananas, add extra ice cubes and expect a slightly thinner texture.
For best flavor and texture, serve the shake immediately. Stored in the fridge it will keep up to 24 hours—shake before serving. Peanut butter balls store in an airtight container in the fridge for 4–6 days.
Peanut Butter Cup Protein Shake FAQs
Frozen bananas produce the creamiest, ice-cream–like texture. Fresh bananas will work but the shake will be thinner unless you add ice.
Yes. Peanut butter powder can replace regular peanut butter in the smoothie itself, though it won’t work for making the crunchy peanut butter balls.
Yes. Double the ingredients to make more servings; you’ll likely have extra peanut butter ball mixture if you only make a small number of shakes.
