Use your Hands! 

Let’s get dirty. The best kitchen tool for this blueberry crumble is your hands. So wash them!

Once you get the dough made use your hands to scoop out half of the dough and press the dough into the 9×13 baking dish with your fingers to make the crust.

When you make the blueberry mixture use your hands to toss the blueberries in the cornstarch and sugar.

Spread the blueberry mixture evenly with your hands.

There will be some sugar and cornstarch remaining in the bowl. Pour it in your hand and sift with through your fingers to sprinkle over the top of the blueberries.

Do the same with the remaining dough. Sprinkle the crumbs evenly using your hands.

Everything Blueberries! What to do when you have more blueberries than you need! 

During the blueberry season, we go a little overboard with EVERYTHING BLUEBERRIES. This Blueberry Crumb Bar recipe is my favorite fresh blueberry dessert. 

And picking fresh blueberries at a local farm is pure family fun. Before you go picking be sure to read my tips on how to freeze blueberries. It will save you from ruining your blueberries or having them go bad before you get to use them up.

Plus you can toss some frozen berries in for breakfast smoothie. And we can’t forget the blueberry muffins! Blueberries in baked goods are my weakness.
