Bake to Golden Perfection (40-50 minutes): Bake in the preheated oven for 40 to 50 minutes, or until a wooden skewer inserted into the center of the cake comes out clean. The top should be golden brown and springy to the touch.
05 Step

Cool and Invert (30 minutes): Allow the cake to cool completely in the pan on a wire rack. Once cooled, carefully invert the cake onto a serving platter so the rhubarb layer is on top. Serve and enjoy!
For a richer flavor, try browning the butter before greasing the pan.
If you prefer a less sweet cake, reduce the amount of sugar sprinkled over the rhubarb.
Feel free to experiment with different flavors of gelatin – raspberry or cherry would also be delicious!
Ensure the cake is fully cooled before inverting to prevent it from falling apart.
A dollop of whipped cream or a scoop of vanilla ice cream makes a wonderful addition.
