A simple, wholesome dump cake made with tart rhubarb and sweetened naturally with honey or maple syrup. No refined sugar, five minutes of prep, and a tender, buttery topping make this an easy, feel-good dessert.
Cold butter is essential for a tender topping. If using frozen rhubarb, do not thaw first. For a gluten-free version, use a 1:1 gluten-free baking blend. For a vegan version, use melted coconut oil (added cold) and plant-based milk. If top browns too quickly, tent with foil for last 10 minutes. Leftovers keep in refrigerator for up to 5 days and can be frozen for up to 3 months.
