Ingredients

  • 2 qt. blackberries or plums
  • 2 c. sugar
  • 5 Tbsp. cornstarch
  • 1 tsp. vanilla
  • 1 c. margarine or butter
  • 1 1/2 c. brown sugar
  • 1/2 tsp. salt
  • 2 c. uncooked oatmeal
  • 1 1/2 c. flour
  • 1 tsp. baking powder

Instructions

  1. Cook blackberries or plums with sugar, cornstarch, and vanilla until thick, breaking fresh berries to release juice if needed.
  2. Set aside the berry filling to cool slightly before serving.

Tips & Substitutions

For a thicker filling, increase the cornstarch to 6 tablespoons. If you don't have margarine, butter is a great substitute for a richer flavor. Consider using a mix of berries for added depth or substituting brown sugar with coconut sugar for a different sweetness profile. If you prefer a vegan option, use vegan butter and maple syrup in place of brown sugar.

Serving Suggestions

Serve warm, optionally topped with a scoop of vanilla ice cream or a dollop of whipped cream for added indulgence. This blackberry crumble pairs beautifully with Sweet Yeast Rolls, making it a delightful dessert after a comforting meal. For a complete experience, consider serving alongside a light salad like Dark Lady Salad.

Storage & Reheating

To store leftovers, cover the blackberry crumble tightly with plastic wrap or transfer it to an airtight container. It can be refrigerated for up to 3 days. To reheat, place in a preheated oven at 350°F (175°C) for about 15-20 minutes until warmed through. This will help maintain the crispiness of the topping.

Frequently Asked Questions

Can I use frozen blackberries for this recipe?

Yes, frozen blackberries can be used, but they should be thawed and drained to avoid excess moisture. You may need to adjust the cornstarch slightly to achieve the desired thickness of the filling.

How can I make this crumble gluten-free?

To make the blackberry crumble gluten-free, swap the all-purpose flour with a gluten-free blend and ensure that your oats are certified gluten-free. This will allow everyone to enjoy the dessert without gluten concerns.

What can I add to the topping for extra flavor?

For added flavor in the topping, consider mixing in some chopped nuts like walnuts or pecans, or spices such as cinnamon or nutmeg. This will enhance the overall taste and provide a delightful crunch.
