🥄 Equipment
Muffin tin: you need a 12 cup muffin pan to make this recipe
Mixing bowls
Chef knife
Cutting board
Hand whisk
Large scoop: I use a ¼ cup sized scoop.
Muffin liners: I recommend foil liners or parchment paper liners

🥫Storage
For best results, it is highly recommended that these gluten-free muffins are stored in the fridge instead of room temperature.
Refrigerate: store in an airtight container up to 7 days.
Freeze: store in a freezer safe airtight container up to 3 months.
📖 Variations
- Substitute ½ of the diced rhubarb for diced strawberries
- Coconut oil can be substituted for the butter.
- If paleo, substitute coconut sugar or maple syrup for the granulated sweetener.

💭 Tips
- I highly recommend using either foil or parchment paper liners for these muffins. These type of liners are easier to remove than regular from the muffin than regular paper liners.
- Due to the nature of the ingredients used in this recipe, is best to allow the muffins to cool completely before eating them as they are fragile when warm.
- Be sure the butter is very soft or melted and cooled when mixing it into the topping ingredients.

Carly says
This recipe was amazing! I was wondering if I could use a loaf pan and make rhubarb bread using the same recipe? I'd love to know your thoughts on this!
Shelby Law Ruttan says
Hi Carly, thank you for trying the recipe! Yes, I believe you could make it into a loaf. You would have to adjust the baking time (increase it some). I would bake it at 350 for 40 minutes, or until a toothpick came out clean.

Thanks for the recipe!

Can you use frozen rhubarb?

Hi Kathleen, I have not, but as long as it is frozen when you put it in the muffin, I think you should be fine. Shelby

Baked in a long narrow loaf pan. started checking for fineness at 35 minutes. Done at 40. very tender crumb so cut carefully. Yummy!
Jenny says
I substituted goat’s milk for the cream and water, and apple sauce for the butter in the muffin batter, and coconut oil in the topping, baked for 28 minutes and they were perfect! Thank you!
Nancy-Jean says
The only thing to make this recipe better is with MORE rhubarb. The next time I make them I plan to use half cup to one cup more. Yes, it will make the muffin softer , but oh so flavourful.
