Ingredients

Ingredient Notes

Blueberries – Fresh in-season blueberries are a real treat in this dessert. However, you can substitute with frozen.

Sugar – Granulated sugar adds a touch of sweetness to the blueberries without masking their flavor. You can substitute with brown sugar.

Cornstarch – As the blueberries bake, they release a lot of juices. Cornstarch helps to thicken the juices a bit and make a nice sauce.

Oats – Old-fashioned rolled oats, also called oatmeal, give the topping a nice chewiness. You can substitute with quick-cooking oats but avoid steel-cut oats as they won’t cook in time.

Almonds – Sliced almonds provide extra crunch and texture and the combination of almond and blueberry flavors can’t be beaten!

Butter – Melted unsalted butter gives the topping its crispiness as well as adds flavor.
