01 - 4 cups mixed frozen or fresh winter berries (blackberries, blueberries, cranberries, raspberries)
02 - 1/3 cup granulated sugar
03 - 1 tablespoon cornstarch
04 - 1 teaspoon fresh lemon juice
05 - 1 teaspoon vanilla extract

→ Oat Crumble Topping

06 - 1 cup rolled oats
07 - 1/2 cup all-purpose flour
08 - 1/3 cup light brown sugar
09 - 1/2 teaspoon ground cinnamon
10 - 1/4 teaspoon salt

# How-to Steps:

01 - Set oven temperature to 350°F and allow to reach full heat.
02 - In a large mixing bowl, combine berries, granulated sugar, cornstarch, lemon juice, and vanilla extract. Toss gently until berries are evenly coated.
03 - Pour berry mixture into a lightly greased 8x8 inch baking dish and spread evenly.
04 - In a separate bowl, combine oats, flour, brown sugar, cinnamon, and salt.
05 - Add cold cubed butter to the oat mixture. Using fingertips, rub butter into dry ingredients until mixture resembles coarse crumbs.
06 - Evenly scatter oat crumble topping over berry filling.
07 - Bake in preheated oven for 35 minutes until topping is golden brown and berry filling is bubbling at edges.
08 - Remove from oven and let cool for at least 10 minutes before serving warm, optionally with vanilla ice cream or custard.

# Expert Pointers:

01 -
  • The way the tart berries melt into sweet pockets beneath that butter-rich topping is practically therapeutic after a long day.
  • You can throw this together in about 15 minutes of actual work, then let your house fill with the most incredible aroma while it bakes.
02 -
  • If using frozen berries, do not thaw them first or youll end up with a soggy bottom - they should go in still frozen and will release their juices perfectly during baking.
  • The crumble topping should look fairly dry when youre mixing it - if it clumps together too much, youve probably softened the butter too much and should chill it briefly before baking.
03 -
  • The perfect crumble topping should have various textures - deliberately leave some larger clumps when working in the butter for those irresistible crunchy bits.
  • Place your baking dish on a larger sheet pan before putting it in the oven to catch any potential overflow, saving yourself from the dreaded burnt sugar cleanup.
