Warm Rhubarb Cake Butter Sauce

Warm rhubarb cake with butter sauce is pure comfort in a pan the kind of dessert that takes a tart spring fruit and lets it shine beneath a real old fashioned sauce. When my garden rhubarb starts showing off those pink stalks this becomes the first bake of the season. It is not just for dessert my family sneaks slices at breakfast too

My kids ask for this as soon as rhubarb appears and honestly watching the butter sauce soak into the crumb is always almost as satisfying as that first bite

My favorite ingredient here is rhubarb for its pink color and perky flavor I still remember baking this with my grandma who handed me the job of stirring in the stalks she always said the messier you get the better the cake turns out

Both fresh and frozen rhubarb work well. If using frozen, be sure to thaw and drain thoroughly to avoid excess moisture in the batter.

→ Can I substitute the milk or cream?
