These banana oatmeal protein muffins are hands-down some of the best healthy banana muffins I've ever made. They're soft, fluffy, lightly sweet, and packed with banana flavor, with just the right nutty texture from oats and optional walnuts.

Even better? Each muffin contains ~10 grams of protein, is low fat, and is gluten-free, dairy-free, and easily made vegan. If you leave out the walnuts, each muffin is only about 130 calories, making two or three perfect as a post-workout snack or pre-workout breakfast.

If you love banana bread but want something lighter, higher-protein, and macro-friendly, these banana oatmeal protein muffins will quickly become a staple.

Why You'll Love These Banana Oatmeal Protein Muffins

• Meal-prep friendly (freezer-safe)
• Perfect for breakfast, snacks, or workouts

The Health Benefits of Walnuts

Did you know? Walnuts are significantly higher in omega-3 fats than any other nut, primarily in the form of α-linolenic acid (ALA). ALA is an essential polyunsaturated fatty acid (PUFA) that supports:

• Cellular and nerve function
• Reduced inflammation
• Blood sugar balance
• Skin health and aging prevention

ALA cannot be synthesized by the body, meaning it must come from food - and walnuts are one of the best natural sources. So next time someone tells you all PUFAs are "bad," remember that many are literally essential for life.
