How to Make Warm Rhubarb Cake with Butter Sauce
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your cake bakes evenly from start to finish.
Step 2: Prepare the Baking Pan
Grease your baking pan thoroughly with butter or non-stick spray. This will prevent the cake from sticking when it’s done.
Step 3: Mix Dry Ingredients
In a large mixing bowl, combine:
The plain flour
White sugar
Baking powder
Salt
Whisk these dry ingredients together until well blended.
Step 4: Incorporate Wet Ingredients
Add the milk and melted butter to the dry mixture. Stir until just combined; be careful not to overmix.
Step 5: Fold in Rhubarb
Gently fold in the cut rhubarb pieces until they are evenly distributed throughout the batter.
Step 6: Bake the Cake
Pour the batter into your prepared baking pan. Bake in the preheated oven for about 45 minutes or until a toothpick inserted in the center comes out clean.
Step 7: Make the Butter Sauce
While the cake is baking, prepare your butter sauce by melting:
1. The stick of butter in a saucepan over medium heat.
2. Add granulated sugar and cream. Stir until everything is combined and smooth.
Step 8: Serve Warm
Once baked, let your Warm Rhubarb Cake cool slightly before slicing. Drizzle generous amounts of warm butter sauce over each slice before serving. Enjoy!
