1poundplumsor about five medium sized pitted and sliced into 1/4" wedges
1tablespoonlemon juiceif your plums aren't very tart
1/4cupbrown or regular cane sugar
Preheat oven to 350°F.
In a large bowl, blend together dry crumble topping ingredients, and then cut butter into flours either with a knife, pastry blender, or blend with fingers, until the largest pieces of butter are about pea-sized.
Place plum slices into a glass or ceramic baking dish, and add lemon juice and sugar. Stir to combine, then pour the crumble evenly over the plums.
Bake for 35 minutes, then check to see if fruit is bubbling up through the crumble and the top is starting to brown. If not, return to oven for another 10 minutes.
Serve warm with whipped cream or custard, or enjoy on its own.
