Soft, rich, deeply chocolatey, and made in just one bowl – double chocolate protein muffins! We love a muffin recipe in my house. They’re the perfect handheld toddler snack and an ideal grab-and-go treat for a breastfeeding mom like me. Similar to my 4-ingredient healthy banana muffins, I often have to make a double batch of these double chocolate protein muffins because let me tell ya, they disappear FAST. But I’m totally ok with that. They’re gluten-free, dairy-free, even refined sugar-free, and have an extra boost of protein! Make these muffins once and you’re whole family will be hooked.

And if you’re not in much of a chocolatey mood – give my 6-ingredient vanilla protein muffins a try!

Why You’ll Love These Chocolate Protein Muffins

They taste like a real chocolate muffin. Soft, moist, and packed with rich double chocolate flavor – thanks to the Aloha chocolate protein powder AND chocolate chips folded throughout. Nobody will ever guess these are a “healthy” muffin.
Made in one bowl. Wet ingredients, dry ingredients, chocolate chips – all in one bowl. Minimal dishes, maximum chocolate. That’s the deal!
Gluten-free and dairy-free. Made with oat flour and non-dairy milk, these muffins are completely gluten-free and dairy-free without compromising on texture or flavor.
High in protein. Aloha chocolate protein powder gives each muffin a serious protein boost, making these genuinely satisfying as a snack, breakfast, or post-workout treat.
Perfect for meal prep. Make one batch on Sunday and you have a healthy, chocolatey snack or breakfast ready to grab all week long. They store beautifully in the fridge and the freezer.
Easy and approachable. No mixer, no complicated techniques. Just one bowl and a muffin tin – if you can stir, you can make these!

Recipe Variations and Substitutions

Protein Powder: This recipe was tested with Aloha chocolate protein powder and is specifically calibrated for its texture and sweetness. If you swap to a different protein powder, keep in mind that results may vary – some powders are drier, sweeter, or have a stronger flavor than others. If your batter seems too thick, add an extra tablespoon or two of non-dairy milk to loosen it up.
Oat Flour: Make your own by blending rolled oats in a food processor or blender until fine. You can also use a gluten-free 1:1 flour blend as a substitute, though the texture will be slightly different.
Oil: I used olive oil, but any vegetable oil works. Or, feel free to use melted butter (dairy or dairy-free) instead!
Maple Syrup: Honey works as a direct substitute. For a less sweet muffin, reduce to ⅓ cup.
Chocolate Chips: Use your favorite – semi-sweet, dark chocolate, or a sugar-free option like Lily’s. Mini chocolate chips are a fun option that distribute more evenly throughout the batter.
Add-Ins: Stir in ¼ cup of chopped walnuts or pecans for a nutty crunch, or swirl in a tablespoon of peanut butter per muffin before baking for a chocolate-peanut butter situation that is truly next-level.

Storage Tips

At room temperature: Store cooled muffins in an airtight container at room temperature for up to 2 days.

In the fridge: These chocolate protein muffins keep well in an airtight container in the refrigerator for up to 1 week. Warm individual muffins in the microwave for 20–30 seconds before eating – they come out warm and gooey and taste freshly baked!

In the freezer: These freeze incredibly well and are perfect for long-term meal prep. Let the muffins cool completely, then transfer to a zip-lock freezer bag or airtight container and freeze for up to 3 months. Thaw overnight in the fridge or microwave straight from frozen for 60–90 seconds.
