Tips for the Best rhubarb upside down cake bubbly
- Fresh vs. Frozen Rhubarb: Use fresh rhubarb for a brighter flavor, but if using frozen, ensure it’s fully thawed and drained to avoid excess moisture.
- Packing Brown Sugar: Pack the brown sugar tightly in the measuring cup; this ensures a rich caramelization with the rhubarb, enhancing that bubbly texture.
- Butter Temperature: Make sure your melted butter is slightly cooled before mixing it with the brown sugar and rhubarb to prevent cooking the fruit prematurely.
- Don’t Overmix: When combining wet and dry ingredients, mix just until combined. Overmixing can lead to a dense cake rather than the light, fluffy texture we desire.
- Cooling Time: Allow the cake to cool for 10 minutes before inverting. This helps set the topping and prevents it from sticking to the pan, ensuring a beautiful presentation of your rhubarb upside down cake bubbly.
