Healthy Banana & Peanut Butter Oat Streusel Muffins

Sharing is caring!

If you’re looking for a muffin that’s both wholesome and incredibly satisfying, this is it. Healthy Banana & Peanut Butter Oat Streusel Muffins hit that perfect middle ground between nourishing and indulgent. Moist banana muffin base, swirled with creamy peanut butter and topped with a crunchy oat streusel—they’re as good for meal prep as they are for lazy weekend baking.

These muffins taste like comfort food but are packed with better-for-you ingredients. Ripe bananas add natural sweetness and moisture. The peanut butter gives protein, richness, and that nostalgic flavor we all crave. And oats add fiber and texture, especially in the streusel topping, which is crisp and golden when baked.

They make a great grab-and-go breakfast, afternoon snack, or post-workout bite. And yes, they freeze beautifully. Just warm them up and they taste like they were baked fresh that day.

Kids love them. Adults love them. They’re naturally sweet, filling, and full of flavor. The kind of muffin you reach for without guilt.

You won’t find any refined flour in this recipe. Instead, we use a mix of oat flour and rolled oats. If you don’t have oat flour, it’s easy to make—just blend oats in a food processor until fine.

And let’s talk about the streusel. It’s simple: oats, cinnamon, a little brown sugar, and coconut oil or butter. Sprinkle it on top before baking, and it gives every muffin a golden crown.

Each bite delivers layers of flavor and texture. Soft banana base. Creamy peanut butter. Crunchy oat topping. It’s a triple win.

No mixer required. Just a few bowls and a spoon.

They’re also customizable. Add chocolate chips, chopped nuts, or flaxseed. You can use almond butter instead of peanut butter if you prefer.

They’re sweetened naturally with banana and a touch of maple syrup, which makes them a great choice for anyone looking to cut down on refined sugar without giving up great flavor.

Bake once, enjoy all week. These muffins keep well at room temp for a few days, or in the fridge for longer freshness.

They’re satisfying without being heavy, and they taste like something you shouldn’t feel good about eating—but you totally can.

Once you try these, they might become a staple in your rotation.
