Helpful Tools
How to Make Raspberry Crumble
Begin by preheating the oven to 350 degrees Fahrenheit and then grease a 9 inch pie dish with non stick spray and set it aside.
Then carefully mix the raspberries, ½ cup of brown sugar, cornstarch, lemon juice and vanilla with a rubber spatula in a medium mixing bowl. Pour the raspberry mixture into the previously prepared pie dish.
In a separate mixing bowl, mix together the oats, flour, pumpkin pie spice and remaining brown sugar.
You can either pour the dry ingredients into a food processor to work the butter in, or use a fork or your fingers. Work the butter into the dry ingredients until the mixture becomes crumbly.
Sprinkle the crumble topping evenly over the raspberry filling.
Place the unbaked raspberry crumble into the oven and bake for 30-35 minutes until the topping is golden brown and the filling is bubbly.
Remove the crumble from the oven and allow it to cool for a few minutes. Serve warm with ice cream or on its own!
How to Store Leftover Raspberry Crumble
You can either store leftovers of this easy raspberry crumble recipe in the pie dish or in an airtight container. If you keep it in the pie dish, be sure to cover it really tightly in plastic wrap. It can be stored at room temperature for about 5 days.
This simple dessert can also be frozen! Transfer leftovers to an airtight container or wrap in plastic wrap. Freeze for up to 3 months.
How do you thicken fruit for a crumble?
To make a thick and gooey filling in your crumble, it is important that you use a thickener like cornstarch. If you don’t have that on hand, tapioca flour and xanthan gum are two great substitutes. Even simply using some flour can help to thicken the fruit mixture!
Do I need to put baking powder in my crumble topping?
For this simple raspberry crumble recipe, you do not need to use baking powder in the topping. It gets perfectly crisp and crumbly as is since the filling isn’t very liquidy.
Pro Tips for the Best Raspberry Crumble with Oats
- If you don’t have a pie dish, you can use an 8×8 baking dish since it holds about the same amount. You could also double the recipe and use a 9×13 inch dish, though the crumble may end up a little thin.
- For the most delicious results, serve warm raspberry crumble with cold vanilla ice cream or homemade whipped cream.
- Make sure that you carefully measure out the ingredients for the topping so it is the right consistency. Otherwise, it could be too dry or too wet.
