Summer Berry Crisp
To make a berry crisp, toss mixed berries with a little sugar and a spoonful of cornstarch to thicken their juices, spread them in a dish, and cover with a crumbly topping of oats, flour, brown sugar, and butter. Bake at 190 °C for about 40 minutes until the fruit bubbles at the edges and the top is golden. The cornstarch keeps the filling from being runny, and the oat topping gives it crunch. Serve warm with ice cream.
A berry crisp is the easiest, most generous way to turn a summer berry harvest into dessert — juicy fruit bubbling under a crunchy, buttery oat topping, served warm with ice cream melting into it. There’s no pastry to fuss with, it comes together in minutes, and it works with any berries you’ve got, fresh or frozen.
Thicken the fruit
Berries are wonderfully juicy, which is lovely on the tongue but runny in a dish. Toss them with a spoonful or two of cornstarch (and a little sugar and lemon) before baking to bind those juices into a glossy, spoonable filling. Then let the crisp cool 10–15 minutes — it sets further as it rests.
The oat topping
What makes it a crisp is the oats in the topping, which bake up crunchy against the soft fruit. Rub cold butter into oats, flour, and brown sugar until crumbly with pea-sized bits, and scatter it on thick.
Fresh or frozen
This is a year-round dessert: use ripe summer berries, or frozen ones straight from the bag (add an extra spoonful of cornstarch and a few more minutes). A great way to bake a frozen harvest in January.
Make it yours
- Mix the fruit: berries with peaches, plums, or apple.
- Nutty: add chopped almonds or pecans to the topping.
- Spiced: cinnamon, or a little ginger.
- Zippy: more lemon, or lemon zest in the fruit.
Serve it warm, ideally with vanilla ice cream or pouring cream. It’s the effortless, crowd-pleasing dessert of berry season — and it makes any pile of summer fruit taste like a treat.

Frequently asked questions
Can I use frozen berries?
Yes — a crisp is one of the best uses for frozen berries, so you can make it year-round or from a frozen summer harvest. Use them straight from frozen (don't thaw), and add an extra spoonful of cornstarch since frozen fruit releases more liquid. You may need a few extra minutes in the oven. Fresh summer berries are lovely, but frozen work beautifully.
What's the difference between a crisp, a crumble, and a cobbler?
They're close cousins. A crisp has a topping of oats (and often nuts) that bakes up crunchy; a crumble has a similar streusel topping usually without oats; and a cobbler has a biscuit or cake-like topping dropped over the fruit. All are baked fruit desserts with a topping — this recipe is a crisp because of the oats, which give it that signature crunch.
How do I keep the filling from being runny?
Berries are very juicy, so toss them with a thickener — a spoonful or two of cornstarch (or flour) — before baking. This binds the juices into a glossy, spoonable filling rather than a watery one. Also let the crisp cool for 10–15 minutes after baking; the filling continues to set as it cools. Frozen or very juicy berries need a little extra cornstarch.
