🔪 How to Make These Lemon Blueberry Crumb Bars
Making these blueberry crumb bars is so easy. Just follow the step-by-step instructions here or in the recipe card at the bottom of the post for a delicious dessert in no time at all.
Step 1: Prepare the oven and mix together the sugar and cornstarch
Preheat the oven to 375 degrees. In a small bowl, whisk together the ½ c sugar and the cornstarch. Set aside for a moment.
Step 2: Make the blueberry filling
Zest the lemon, and squeeze its juice over the bowl of blueberries. Sprinkle the sugar and cornstarch mix over them and stir them well. Set them to the side.
Step 3: Make the crumb topping
In a large bowl, mix the flour, sugars, baking powder, cinnamon, and salt. Add the butter into the flour using a pastry cutter to create fine crumbs. In a small bowl, whisk the egg and the vanilla together and add it to the flour, continuing to cut it into the flour mixing using a pastry cutter.
Step 4: Layer the bars
Spray a 9” x 13” baking pan using cooking spray and spoon about half of the crumb mixture into the base of the dish and using your hands, press down firmly to create a base layer. Stir the blueberries well before spreading them on top of the bottom layer.
Step 5: Bake the bars
Sprinkle the remaining crumb mixture over the top of the berries. Place in the oven and bake for 45 minutes. The top should turn lightly golden brown. Remove and allow to cool slightly before slicing and serving!
