And this berry crisp is as easy to make as it is delicious! It takes just 10 minutes to prep this recipe, which makes it a quick dessert recipe that’s perfect for busy summer nights.

Ingredient notes and substitutions
- Oats: I’ve only made this recipe with old-fashioned rolled oats. I haven’t tried using quick oats in the topping.
- Brown sugar: I use light brown sugar. If you only have dark brown sugar, feel free to use that instead.
- Butter: I use salted butter. If you’re using unsalted butter, add a couple of pinches of salt to the topping.
- Berries: You can vary the types of berries depending on what you have on hand and what you like.
- Lemon juice: I highly recommend using fresh lemon juice instead of bottled lemon juice as bottled lemon juice can have an off taste to it.
