Preheat the oven to 375 degrees F.
Start by mixing all of the ingredients for the strawberry and rhubarb compote in a medium sized bowl. Then let it sit for about 10 minutes so the sugar melts and the strawberries and rhubarb are nice and syrupy.
Pour the strawberry rhubarb mixture into a 9x13 pan or any baking dish that is large enough. Set aside.
To make the biscuits. In a large bowl or a food processor, mix the flour, baking powder, sugar and salt. Next add the cold butter and mix using a pastry blender or pulsing in the food processor until you get a fine crumb. It should look like sand. Add in the half and half and mix until the dough starts to form, then turn it out on a cold floured work surface.
Knead until the dough comes together. Only about 3-5 turns as you don’t want to over knead the dough and have your biscuits turn out tough and dense. Shape the dough into a square half the size of the baking dish. Then slice so that you get 9-12 biscuits.
Arrange the biscuits on top of the strawberry rhubarb mixture in the pan. I like to make mine into a checkered pattern.
Brush the biscuits with some heavy whipping cream then sprinkle with sugar. This helps the tops of the biscuits get nice and golden brown.
Bake until the biscuits are cooked all the way through, their tops are golden brown and the strawberry rhubarb mixture is bubbling. About 35-45 minutes. It took mine 45 minutes.
To serve, scoop warm into a bowl and top with some homemade whipped cream or vanilla ice cream.
