Heavenly Rhubarb Cake with Warm Butter Sauce

Preheat oven to 350°F (175°C). In a large bowl, whisk together flour, sugar, baking powder, and salt. In another bowl, combine milk, egg, vanilla, and melted butter. Add the wet ingredients to the dry and mix just until combined. Gently fold in the diced rhubarb.

2. Bake the Cake:
Pour the batter into a greased 9×13-inch baking dish. Bake for 35–40 minutes, or until a toothpick inserted into the center comes out clean. Allow to cool slightly.

3. Make the Butter Sauce:
In a saucepan, melt butter over medium heat. Stir in sugar and heavy cream. Bring to a gentle boil, stirring constantly until the sauce thickens slightly (about 3–5 minutes). Remove from heat and stir in vanilla extract.

4. Serve:
Cut the warm cake into squares and pour the hot butter sauce generously over each serving. Enjoy warm for the best experience.
