FAQs
Can I use frozen rhubarb for this recipe?
Yes, but thaw it completely and pat dry before adding to the dough to prevent excess moisture.
Do these cookies taste very sour?
Not at all! Brown sugar softens the tartness of rhubarb, making a sweet-tangy balance.
Can I make these dairy-free?
Absolutely—substitute butter with a dairy-free alternative like vegan butter or coconut oil.
Why are my cookies too flat?
This usually happens if the butter was too soft or melted. Chill the dough before baking to help them hold shape.
What other fruits can I substitute for rhubarb?
Chopped strawberries, cranberries, or apples work beautifully if rhubarb isn’t in season.
