Strawberry & Plum Crumble

1. Preheat oven to 375 degrees F and place rack in middle position.
2. Using a medium mixing bowl, add in icing sugar, flour and cinnamon. Add plums and strawberries and mix well. Add mixture into 4 individual size oven safe ramekins.
3. Combine baking powder, sugar, flour, salt and oats in a small bowl and mix to combine. Add in beaten egg and mix with hands until thoroughly combined. You should be left with bits of mixture that resemble coarse breadcrumbs.
4. Sprinkle the mixture over top of the ramekins and drizzle the melted butter over the crumb mixture. Bake for 40 minutes or until the topping is golden brown and the juice from the berries has bubbled up the sides.
