Ingredient Notes
- Blueberries. The fresher the better! Frozen berries would work too.
- Lime zest. Remove the zest from your lime with a zesting tool or microplane grater. Use our guide on how to zest a lemon for best tips and tricks.
- Quick oats. Make sure to use quick cooking oats, not rolled oats or steel cut.
Easy Instructions
The best thing about blueberry lime crumble, besides the taste, is how EASY it is to make!
- Combine fruit- Toss your blueberries with flour, lime zest and sugar. Then add the berries to the bottom of a casserole dish.
- Make Crumble. Combine the crumble topping ingredients. Sprinkle over the blueberries.
- Bake. Bake until bubbly and browned.
That’s it. After a few minutes to let the crumble cool, top with whipped cream or ice cream and enjoy!
Tips and Tricks
- If using frozen blueberries, let them thaw completely before adding to the recipe.
- Try this recipe with blackberries or raspberries for a different berry-lime flavor.
- Add the ice cream or whipped cream topping to individual portions just before serving. The cold cream will melt into the warm crumble as you eat. It’s out-of-this-world delicious!
- I love Blueberry Crumble best served warm. It’s also tasty served at room temperature or chilled if preferred.
- Try our blueberry sweet rolls next for a gooey warm breakfast treat.
Recipe FAQs
Cover leftovers with foil or transfer to an airtight container. Refrigerate and enjoy leftovers within 3 days for best taste.
You can absolutely make this recipe with lemon zest instead of lime. The flavor will be a bit different but lemon and blueberry always pair well together!
Yes, salted butter will work just fine! I just prefer unsalted because the flavor is more consistent across brands. Different brands of salted butter contain different quantities of salt, which could affect the taste of your crumble a bit.

What’s better than blueberry crumble? Blueberry Crumble with a hint of lime flavor. Don’t forget that extra dollop of whipped cream on top!
This looks wonderful! I grew up eating cool whip, too. It was the only kind of ‘whipped cream’ we ever had 🙂
