Rhubarb Muesli Crumble is a delicious and healthy dessert that combines the tartness of rhubarb with the crunchiness of muesli. The rhubarb is cooked until soft and sweetened with a touch of honey, then topped with a mixture of muesli, butter, and brown sugar. The crumble is baked until golden and crispy, creating a delightful contrast of textures. Serve this warm dessert with a scoop of vanilla ice cream for a perfect balance of flavors.
