Preheat the Oven:
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper or a silicone baking mat.
Make the Cookie Dough:
In a large mixing bowl, cream the butter and sugar together until light and fluffy.
Beat in the egg and vanilla extract.
In a separate bowl, whisk together the flour, baking soda, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients and mix until a soft dough forms.
Prepare the Crumble Topping:
In a small bowl, mix the melted butter, flour, brown sugar, and cinnamon until crumbly.
Assemble the Cookies:
Scoop tablespoons of cookie dough onto the prepared baking sheet, spacing them about 2 inches apart.
Make a small indentation in the center of each dough ball using your thumb or the back of a spoon.
Fill each indentation with a teaspoon of blueberry filling.
Sprinkle the crumble topping over the blueberry filling.
Bake the Cookies:
Bake in the preheated oven for 12-15 minutes, or until the edges are lightly golden.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
