FAQs
Can I use frozen rhubarb instead of fresh?
Yes! Thaw frozen rhubarb completely and pat dry with paper towels to remove excess moisture before adding to the batter.
My rhubarb is very tart. Should I increase the sugar?
You can increase the sugar by 2-3 tablespoons if your rhubarb is particularly tart, or try adding a few drops of liquid stevia for sweetness without additional calories.
Can I substitute the Greek yogurt with regular yogurt?
Regular yogurt contains more moisture than Greek yogurt, so you’ll need to reduce the applesauce to 2 tablespoons if making this substitution.
How do I know when the muffins are done baking?
Insert a toothpick into the center of a muffin—it should come out clean or with a few moist crumbs, but no wet batter.
Can I make this recipe vegan?
Yes! Substitute the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) and use plant-based yogurt instead of Greek yogurt.
