Ingredients for triple berry crisp

For filling: 

  • Berries – I’ve used a combination of blueberries, raspberries, and blackberries.
  • Dark brown sugar – Dark brown sugar will add sweetness to the filling.
  • Lemon juice and lemon zest – Both lemon juice and lemon zest will give the filling a bright lemon flavor.
  • Vanilla bean paste – Vanilla bean paste will add a sweet vanilla flavor. 
  • Cornstarch – Cornstarch will help thicken the filling.
Brown sugar, butter, and oats in a bowl.

For topping: 

  • Old-fashioned oats – Old-fashioned oats are perfect because they get toasty and crunchy.
  • Butter – Butter will help create the crumbles and help them brown in the oven.
  • All-purpose flour – All-purpose flour will make up some of our crumbly toppings. 
  • Dark brown sugar – Dark brown sugar will add a touch of sweetness.

What is vanilla bean paste?

Vanilla bean paste is a thick, sweet, concentrated vanilla bean product. 

You’re able to see the little specks of vanilla, and the flavor is front and center.

Vanilla bean paste is available online for purchase, or in gourmet food shops. 

If you don’t have access to vanilla bean paste, you can always just use vanilla extract or an actual vanilla bean!

To get all of the good pulp out of a vanilla bean, simply cut it down the middle lengthwise, and use the back of your knife to scrape it out.

Why use cornstarch?

Cornstarch is an excellent thickener to use in fruit-based desserts, because, unlike flour, cornstarch keeps the fruit sauce thick and clear, without making it cloudy. 

Flour also has a tendency of tasting floury if you use too much.

Topping fruit crisp

Here are some great topping ideas for this triple berry crisp:

  • Ice cream (vanilla, strawberry, or dark chocolate would be delicious here)
  • Whipped cream
  • Yogurt with a drizzle of honey

Using frozen berries

If you can’t find fresh berries, feel free to use frozen instead!

Frozen fruits are flash frozen at the peak of freshness so they’re always ripe and juicy.

Storage and leftovers 

Any leftover triple berry crisp can be stored in the refrigerator for up to 2 days.
