Lemon Berry Oatmeal Muffins – These healthy muffins are made without any oil, eggs, refined flour, or sugar. Naturally sweetened, made with rolled oats, and speckled with raspberries and blueberries, these light lemony muffins are sure to be a new favorite. (Gluten Free & Vegan!)

So it turns out, I have a lot of expectations when it comes to making muffins. They’re one of our go-to options for packing in lunches or munching on for snacks, so I really want them to be made from wholesome ingredients.
That said, I don’t want them to taste healthy. I’m looking for great texture that’s not to dense and plenty of yummy flavor. These healthy lemon berry oatmeal muffins have it ALL.


First off, they’re gluten free AND vegan, which I can’t believe. The texture is light and fluffy while still substantial enough to feel really satisfying. They’re naturally sweetened with pure maple syrup, and instead of flour and I use ground oatmeal made from (gluten free) rolled oats.
I tested this recipe many times to nail down the proportions I liked the best, and these really just hit the mark. We couldn’t decide on lemon raspberry muffins or lemon blueberry muffins, so I made both by tossing in a little of each! The colors look so beautiful and the flavor is hard to beat, though we also tried them with just blueberries or just raspberries and loved them every single way.
I’m thinking there are a LOT more oatmeal muffins in my future…

Notes on these Healthy Lemon Berry Oatmeal Muffins:
Best Muffin Pan Ever. Every time I post a muffin recipe, I always want to share my favorite muffin pans. They’re nonstick, which means you don’t need muffin liners. They’re also easy to wash and care for, and even come in other colors. I use them for All The Things!
Gluten Free Notes: Not everyone who is gluten free can tolerate oats. I get REALLY sick with gluten, but have never yet reacted badly to oats. Oats themselves contain no wheat gluten, but cross-contamination in processing and farming practices often mean that if you eat gluten free you’ll want to be sure to buy certified gluten free oats. I typically order these in bulk, or pick up some from Trader Joe’s.
Let’s talk flour. In this recipe, I have you make your own oatmeal flour (which literally takes 1 minute). To do this, you can use a food processor or a blender. I prefer using my blender because it’s so much faster and the texture can get *really* fine, but either works. If you prefer to save time, you can totally use store-bought oat flour (be sure it’s certified gluten free, if needed). It’s up to you!
Can I Use Frozen Berries? Yes, but know that they will have a *slightly* more wet texture. I’ve read a LOT of different methods for reducing the impact of using frozen berries. Some recommend thawing the berries and draining off any extra liquid. Others recommend tossing your berries in 1-2 Tbsp of the flour so they don’t all sink to the bottom. I haven’t noticed a huge difference with either of these, but people swear by these methods, so maybe they’ll help you?
Swaps and substitutions: You can use any kind of milk you like here–cashew, almond, coconut, soy, rice, hemp, or even dairy (if you’re not vegan/dairy free). As for the nut butter, I like cashew butter best because it’s the most neutral, but not everyone keeps it on hand. (I get it at Thrive or Sprouts for the best price.) If you swap it out for almond butter, you may want to add a little extra lemon zest or one of my lemon boosts below. Lastly, you can sub out the syrup for other liquid sweeteners, like agave or honey (if not vegan).
Pump up the Lemon! If you want even more lemon flavor, you can add 1-2 drops (food grade!) lemon essential oil, or 1/4 tsp lemon extract.

So tasty! Moist and hearty. I used coconut milk and peanut butter since they are what I had on hand. Half with the berries, half without. Keeping this recipe!
Oh yum! I bet that was delicious! Thanks so much for taking the time to leave a review. I appreciate it so much!
