½cupunsalted butter, softened to room temperature (1 stick)
½cupgranulated sugar
½cupdark brown sugar
2large eggs, at room temperature
1teaspoonvanilla extract
1Tablespoonlemon juice (from about half a lemon)
Zest from one lemon (about 2 teaspoons)
Streusel
½cupall purpose flour
¼cupgranulated sugar
2Tablespoonsunsalted butter, melted
Instructions
Preheat the oven to 350°F. Line a baking sheet with parchment paper.
Prepare the streusel by mixing the flour, sugar, and melted butter in a small bowl with a fork until it forms a crumbly mixture. Set aside.
In a small bowl, toss the fresh or frozen blueberries in one tablespoon of flour. Set aside.
In a large mixing bowl, whisk together the remaining flour, cornstarch, baking soda, salt and cinnamon. Set aside.
In a separate mixing bowl, beat the softened butter with the granulated sugar and brown sugar with a stand mixer or with a hand mixer until it looks creamy.
Beat the eggs, vanilla extract, lemon juice, and lemon zest into the butter mixture until it’s well combined.
Add the dry ingredients to the wet ingredients. Gently mix the dough with a large spoon or spatula just until there is no visible dry flour.
Gently fold the blueberries into the dough.
Use a large cookie scoop or two spoons to shape the cookie dough into balls that are about 2 inches in diameter. Place them on the baking sheet spread out at least 2 inches apart. Gently flatten the tops of the cookies and sprinkle on the streusel, pressing it in to get the streusel to stick to the sides.
Bake for 12 to 15 minutes, just until they start to turn golden around the edges. Allow them to cool and firm up for a few minutes on a baking sheet, then transfer to a cooling rack & enjoy!!
Notes
You can use either fresh or frozen (not thawed) blueberries. Just don't forget to toss them in a tablespoon of flour, to prevent the color from bleeding and to avoid thin, flat cookies from excess moisture.
Store cooled cookies in an airtight container for up to a few days.
