Cut the cake into squares and drizzle warm butter sauce over each serving before indulging.

Gently fold the ingredients together to keep it light and airy. - **Add Zest**: A little lemon zest in your batter can elevate the flavors to a whole new level. - **Keep an Eye on Baking Time**: Ovens can vary, so start checking for doneness around the 45-minute mark. - **Serve Warm**: Enjoy this cake while it’s warm; it truly enhances the flavors! ## Fun Variations & Topping Ideas ### Variations: - **Berry Twist**: Add a handful of strawberries or blueberries for an extra fruity zing. - **Nutty Crunch**: Incorporate chopped nuts into the batter for added texture. ### Toppings: - **Whipped Cream**: A dollop on top takes it to dessert heaven. - **Ice Cream**: Vanilla ice cream pairs beautifully with the tartness of the rhubarb. ## Storing and Reheating ### Storing: Keep the leftover cake covered in an airtight container at room temperature for up to three days.
