Summer baking is within sight! Haley here from If You Give a Blonde a Kitchen and I am so happy that blueberries are coming back in season soon.

They are my favorite fruit to eat and  to bake with. I made these blueberry crumble bars and they are just as delicious as they look!

Served with a crumble oat topping, these bars are bursting with blueberries. Each bite is filled with fruity flavor and butter crust.

I love this recipe because the crust and the crumble are the exact same mixture. It makes the bars super easy to make. Use flour, oats, brown sugar, cinnamon and cold butter to make the mixture.

It’s vital to use cold butter so the crust stays sturdy enough to hold the blueberry filling. The butter also serves as a way to keep the crumble, well, crumbly.

The blueberry filling starts oozing with juices when the bars bake. I used sugar to get the juices flowing, cornstarch to keep the filling together, and lemon juice and zest for extra flavor.

My favorite part of making blueberry crumble bars is when I see the filling bubbling. Not only does it make me want to take a bite right then and there, but it also means the bars are done baking!

Resist the urge to cut the bars right away. Let them cool completely. If you cut them too early, they will be pretty messy to eat. Sometimes I even refrigerate my bars if I’m making them on a hot day.

If you have a good ice cream shop nearby, pick up a gallon of french vanilla ice cream. Serve a scoop with a blueberry bar and your tastebuds will be in heaven.
