The Baker Upstairs: blueberry crumb bars


blueberry crumb bars


Happy Monday! I'm back home from our family vacation to San Diego and trying to readjust to normal life. I'll confess it was pretty difficult to leave those sunny skies and sandy beaches behind! We had the best time and did so many fun things with the girls, and it was the perfect trip for relaxing and enjoying our time together. Just before we left for vacation my mom asked me if I could come up with a fun birthday treat for one of her friends at work, and I decided to make these delicious blueberry crumb bars. They're a perfect spring treat!

I love the buttery, crumbly layer on top, contrasted with the juicy blueberry layer. These bars come together really quickly and are simple and easy to make!

Blueberry Crumb Bars

1 cup white sugar
1 teaspoon baking powder
1/4 teaspoon salt
3 cups all-purpose flour
1 cup cold butter, cut into pieces
1 egg, beaten
Zest and juice of one lemon
4 cups fresh blueberries
1/2 cup white sugar
4 teaspoons cornstarch

Preheat oven to 375. Grease (or line with foil) a 9 x 13 pan. In a medium bowl, whisk together sugar, baking powder, salt, and flour. Cut in the butter using two knives or a pastry blender, until pieces are no bigger than pea sized. Stir in the egg to form a crumbly dough. Pat half of the dough in an even layer in the prepared pan. In a medium bowl, whisk together the lemon zest and juice, 1/2 cup sugar, and cornstarch. Toss the blueberries in the mixture, and spread the blueberries on top of the dough in the pan. Crumble the remaining dough evenly over the blueberries. Bake 45-50 minutes, or until lightly browned. Let cool before slicing and serving.
