Step‑by‑Step Instructions for Rhubarb Upside‑Down Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it’s heating, grease a 9×13-inch or round cake pan with butter or non-stick spray to ensure your Rhubarb Upside-Down Cake releases easily after baking. This step sets the stage for a perfectly baked cake with a golden top.
Step 2: Prepare the Rhubarb Base
Slice the rhubarb into ½-inch pieces and evenly spread them on the bottom of your prepared pan. Sprinkle ¾ cup of sugar over the rhubarb, allowing its natural juices to mingle with the sweetness. Dot the mixture with 2 tablespoons of butter, enhancing the caramelization as the cake bakes, and creating that irresistible sticky topping.
Step 3: Make the Cake Batter
In a mixing bowl, cream together ½ cup of butter and 1 cup of sugar until the mixture is light and fluffy, about 3-5 minutes. Add the large egg and blend well. In another bowl, mix 2⅔ cups of flour, 2 teaspoons of baking powder, ¾ teaspoon of ground nutmeg, and ¼ teaspoon of salt until combined. Gradually alternate adding the dry ingredients with ⅔ cup of milk to the wet mixture, stirring until smooth.
Step 4: Assemble the Cake
Once your batter is ready, pour it carefully over the prepared rhubarb in the pan. Use a spatula to spread the batter evenly, ensuring it covers all the rhubarb. This will create a delightful layer that perfectly complements the tangy fruit beneath, setting you on the path to a delicious Rhubarb Upside-Down Cake.
Step 5: Bake the Cake
Place your cake pan in the preheated oven and bake for 40 to 45 minutes. Keep an eye on it, and look for a golden-brown top and a toothpick inserted into the center coming out clean. This visual cue lets you know that your cake is baked to perfection and ready to be inverted.
Step 6: Invert & Serve
After baking, remove the cake from the oven and allow it to cool in the pan for about 10 minutes. Then, carefully invert it onto a serving plate, allowing the caramelized rhubarb to take center stage. Serve your warm Rhubarb Upside-Down Cake with sweetened whipped cream for an extra touch of deliciousness.

How to Store and Freeze Rhubarb Upside-Down Cake
Fridge: Store leftover cake in an airtight container in the fridge for up to 3 days. It remains moist while the flavors continue to meld together beautifully.
Freezer: Wrap slices tightly in plastic wrap or aluminum foil, then place them in a freezer-safe bag. Your Rhubarb Upside-Down Cake can be frozen for up to 2 months; just thaw overnight in the fridge before enjoying.
Reheating: To serve, reheat individual slices in the microwave for about 20-30 seconds, or in a preheated oven at 350°F (175°C) for 10 minutes, ensuring a warm, cozy treat.
Serving Tip: For the best experience, serve your cake warm, optionally pairing it with sweetened whipped cream or vanilla ice cream for that extra touch of indulgence.

Expert Tips for Rhubarb Upside-Down Cake
• Use Fresh Rhubarb: Fresh rhubarb ensures the best flavor. If using frozen, thaw it thoroughly and drain excess moisture to prevent a soggy cake.
