Wholesome blueberry crumble bars made with walnuts, oats, dates and a few other basic ingredients. Have them for a quick breakfast, snack or serve with ice cream for dessert.

Meet my favorite summer dessert – Blueberry crumble bars. Or any crumble bar, really. Ideally topped with a good scoop of ice cream.

I made these bars for the first time a few weeks back for my little bachelorette party. I’m happy to report that it was a hit. Everyone loved it!

I knew I wanted to create a new crumble bar recipe for the summer and a blueberry crumble seemed like a good way to go. These are inspired by my nut-free strawberry vanilla crumble bars – A recipe I created 2 summers ago (has it really been that long?!). I did change a few things to make them easier, including skipping the extra step of making a chia jam with the fruit. Here, I kept it simple and used the fruit as is.

With my strawberry crumble bars, I wanted to create a nut-free recipe, so I used sunflower seeds. For this recipe, I decided to go another way and used walnuts. Of course you can stick with sunflower seeds if you have an allergy (or if you want a cheaper option), but I have to say, the walnuts pair beautifully with the blueberries.

How to Make your Own Crumble Bars:

This recipe is versatile and I encourage you to make it your own, using ingredients you have on hand!

• Change the Fruit: Try sliced or diced strawberries, peaches, raspberries, blackberries or other fruits you have on hand. I think I’ll try cherry next.
• Make a Fruit Jam: Instead of using whole blueberries, you can easily make a blueberry jam using the same steps as I did with this recipe. You could make a chia jam using many different fruits!
• Use Other Nuts or Seeds: As I said earlier, I did make similar crumble bars using sunflower seeds. You could also try sliced almonds or pecans. Let me know if you try any alternatives!
• Substitute the Butter/Margarine: I haven’t tried it yet, but you could probably use melted coconut oil instead of butter/margarine in this recipe. Just note that it will affect the flavor. I would also recommend adding a pinch of salt.

And that’s it! I love serving this recipe with ice cream for a real summer treat. I’m working on an ice cream recipe at the moment (which is sweetened with dates). It’s also great eaten as is for a quick breakfast on-the-go. (Update: Here’s the ice cream recipe!)
