Ingredients for Individual Mixed Berry Oat Crisps

- 1 (12-ounce) package frozen mixed berries (or fruit of your choice)
- 1 tablespoon cornstarch
- ⅓ cup packed dark brown sugar
- ¼ cup oat flour
- ¼ cup rolled oats
- ¼ cup chopped walnuts (optional, or substitute with pecans)
- ¼ teaspoon ground cinnamon
- 3 tablespoons vegan butter or regular butter (chilled)
- Ice cream, for serving (try Nada Moo coconut ice cream for a vegan option)
Step-by-Step Instructions
- Preheat the oven to 425°F (220°C).
- In a bowl, mix the frozen berries with the cornstarch. Let sit for 20 minutes to allow the berries to release their juices.
- In a separate bowl, combine the dark brown sugar, oat flour, rolled oats, chopped walnuts, and cinnamon.
- Chop the chilled butter into small pieces. Use a fork (or your fingers) to incorporate it into the oat mixture until it becomes crumbly. Avoid overmixing.
- Divide the berry mixture evenly into individual skillets or ramekins.
- Spoon the crumble mixture on top of each berry-filled dish, covering the berries evenly.
- Bake for 20-30 minutes, depending on the depth of your dishes. The crisps are done when the top is golden brown and the berries are bubbling.
- Let cool for 15 minutes before serving. Top with a scoop of ice cream and enjoy!
Perfect Pairings: Sauce and Topping Ideas
While ice cream is a classic topping, try drizzling your crisps with a homemade caramel sauce or a dollop of whipped coconut cream for a dairy-free twist. For a tangy contrast, a spoonful of Greek yogurt or a sprinkle of lemon zest can elevate the flavors beautifully.
Make It Your Own: Recipe Variations
Swap the mixed berries for sliced peaches or chopped apples for a seasonal twist. If you’re nut-free, replace the walnuts with sunflower seeds or simply omit them. For a gluten-free version, ensure your oats are certified gluten-free and use almond flour instead of oat flour.
Quick Tips for Time-Saving Success
Prep the crumble topping ahead of time and store it in the fridge for up to 2 days. Use pre-chopped frozen berries to skip the thawing step. If you’re in a rush, bake the crisp in a single dish instead of individual ramekins to save on assembly time.
Storage and Reheating Made Simple
Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F for 10-15 minutes to restore the crispiness. For a quick fix, microwave individual portions for 30-60 seconds, though the topping may soften slightly.
Equipment Guidance for Best Results
If you don’t have ramekins or skillets, use a muffin tin for mini crisps or a 9×9 baking dish for a family-style version. A pastry cutter or fork works well for blending the butter into the crumble, but your fingers are just as effective—just work quickly to keep the butter cold.
