4 cups rhubarb, diced (see note below about using frozen rhubarb)
2 cups whole milk
6 tbsp. butter, melted
For the Sauce:
1 stick butter
1 cup granulated sugar
¾ cup heavy cream
Instructions
To prepare the cake:
Pre-heat the oven to 350° F.
In a large bowl, whisk together the flour, sugar, baking powder and salt.
Add the diced rhubarb, milk and melted butter; stir just until combined.
Pour the batter into a greased 9-inch x 13-inch baking pan.
Place in the pre-heated oven and bake for 45 minutes or until a toothpick inserted comes out clean.
Remove from the oven and allow to cool.
To prepare the butter sauce:
Using a heavy saucepan, combine the butter sugar and cream.
Bring to a boil, over medium heat; boil for 1 minute stirring frequently.
Remove from heat and let cool slightly.
To prepare for serving:
Cut pieces of cake and serve with a generous amount of warm butter sauce.
The sauce can be gently re-heated on the stove, or in the microwave, if necessary.
Notes
To use frozen rhubarb: thaw the rhubarb first and let excess liquid drain off; don’t squeeze the liquid out, just drain what naturally thaws out of the rhubarb.
