Tips for the Best Protein Muffins

Don’t overmix the batter, or the muffins may become dense. Different protein powders absorb moisture differently, so if your batter seems too thick, add a tablespoon or two of milk until it reaches a thick but scoopable consistency.

Frequently Asked Questions

What protein powder works best?

A vanilla whey protein powder produces the softest texture, but plant-based protein powder also works. You may need to add a little extra milk if using a plant-based powder.

Can I make these gluten-free?

Yes. Use certified gluten-free oats and gluten-free oat flour.

Can I freeze protein muffins?

Absolutely. Let the muffins cool completely, then freeze them in a freezer-safe container or bag for up to 3 months.

How much protein is in each muffin?

The exact amount depends on the protein powder you use, but these muffins typically contain around 10–12 grams of protein per muffin.
