A simple and nostalgic upside down cake combining the tartness of rhubarb with sweet strawberries, featuring a moist buttery cake beneath a caramelized fruit topping.
Use firm, ripe strawberries and bright pink rhubarb stalks for best flavor. For gluten-free, substitute flour with a 1:1 gluten-free baking blend. For dairy-free, swap butter with coconut or vegan butter and milk with almond or oat milk. Allow cake to cool before flipping to prevent sticking or breakage. If rhubarb is too tart, add extra sugar to the fruit topping or dust finished cake with powdered sugar.
