• 1 tsp baking soda
• ½ tsp salt
• 1 tsp cinnamon

Wet ingredients:

• 3 large eggs

The Star:

• 1 cup chopped rhubarb (fresh or frozen is fine)
• Optional: ½ cup raspberries if you want a “rhubarb raspberry muffin” twist

Quick Rhubarb Recipes Tip: Prep the Rhubarb First

Rhubarb’s got a punch. If yours is super tart, sprinkle a tiny bit of your sweetener on it and let it sit while you prep the rest. You don’t need to cook it down or get fancy. Just chop it, toss it, and let it hang out while you do your thing.

Let’s Bake Some Easy Rhubarb Muffins

• Preheat your oven to 350°F (175°C).
  Line your muffin pan or use silicone cups if you’re that person who actually remembers to use them.
• Mix the dry stuff.
  Almond flour, coconut flour, oat fiber, baking soda, salt, and cinnamon. Stir it like you mean it.
• Mix the wet stuff.
  In another bowl, whisk the eggs, yogurt or cottage cheese, melted oil, sweetener, and vanilla. Pro tip: If your cottage cheese is chunky, give it a quick blend. No one wants mystery lumps.
• Combine and fold.
  Dump your dry mix into the wet mix. Stir until just combined. Then fold in your rhubarb and raspberries if you’re using them.
• Scoop and bake.
  Fill your muffin cups about ¾ full. Bake for 22–28 minutes. You’re looking for golden tops and a toothpick that comes out clean (ish).

What You’ll Taste

They’ve got this rich, nutty vibe thanks to the almond flour, but the rhubarb gives it a bit of tang that cuts through the warmth. The oats (okay, oat fiber) give it a muffin-y feel without the carb bomb. So yeah, you can eat two of these and still feel like you’ve made good life choices.

Why These Are the Best Rhubarb Muffins for Low-Carb Folks

We tested different blends of almond flour, Greek yogurt, oat fiber, and rhubarb until it stopped tasting like a science experiment and started tasting like something you’d actually want to eat with your coffee. Or tea. Or standing at the counter while trying not to drop crumbs on your phone.

Why it Works:

• Almond flour rhubarb recipes usually fall flat on texture. Adding coconut flour keeps them from being greasy.
• Greek yogurt makes them moist without adding sugar.
• Oat fiber adds that muffin crumb you miss when you go low-carb.
• Monk fruit sweetener doesn’t leave that weird cooling aftertaste that some sugar substitutes do.

You can swap in other ingredients if you like. These are flexible, forgiving muffins. But this combo? It works.

Need It Sweeter?

Everyone’s got a different sweet tooth. Some folks want their muffins to taste like cupcakes. Others are just trying not to eat like a 12-year-old with a sugar high. If you need to sweeten things up a bit, go ahead—just add a few drops of liquid stevia or a little more monk fruit. Taste your batter. Adjust.

Bonus: Turn These Into Vegan Muffins

Yep. You can make these as a muffin vegan option too. Here’s how:

• Use flax eggs instead of regular eggs (1 tbsp ground flax + 3 tbsp water = 1 egg)
• Sub coconut yogurt for Greek yogurt
• Go with coconut oil, not butter

The result? Still tasty. Still easy. Still something you can pack in a lunch or snack on mid-afternoon without feeling like you wrecked your day.

Who Are These Muffins For?

Honestly, anyone who’s trying to stay healthy without eating dry bricks. These are perfect if:

• You’re doing keto and miss baked goods
• You’ve got rhubarb and no idea what to do with it
• You’re into healthy rhubarb recipes clean eating style
• You love a good batch of rhubarb oatmeal muffins that don’t come with a side of guilt

These muffins also check boxes for people who just want to eat better, stay fuller longer, and not crash by 3 PM.

Don’t Sleep on Rhubarb

Look, recipes for rhubarb get slept on all the time. Most people don’t go beyond pie. But rhubarb’s great in savory stuff, too—though that’s another story. For now, stick with these muffins. They’re easy, fast, and actually taste good. That’s rare in the healthy-baking world.

You Can Freeze These Too

Want to make a double batch? Go ahead. These freeze like a charm. Just wrap ‘em up tight and pop them in the freezer. They’ll last a couple of months, though they probably won’t make it past the weekend.

To reheat, just microwave for 30 seconds or toss in the oven for a few minutes at 300°F.

Try Other Combos

If you love playing with recipes, this one’s your canvas. A few ideas to switch it up:

• Add chopped nuts or seeds for crunch
• Toss in a bit of lemon zest for brightness
• Use chopped strawberries instead of raspberries
• Go full cottage-core and add a spoonful of rhubarb compote on top

You don’t need to be a chef. You don’t need a $500 stand mixer. You don’t even need to know what oat fiber is (though now you do).
