Ingredients
Method
Make the streusel
- Combine flour, brown sugar, cold butter cubes, cinnamon, and salt. Cut the butter into the mixture until you have pea-sized crumbs. Refrigerate while you prepare the cookie dough.
Prepare the cookie dough
- Beat the softened butter with brown sugar and granulated sugar until light and fluffy for 2-3 minutes.
- Mix in the egg and vanilla.
- In another bowl, whisk together the flour, baking powder, and salt. Gradually add the dry mixture to the wet ingredients, stirring just until combined.
Add the blueberries
- Gently fold in the fresh blueberries.
Shape and swirl
- Scoop rounds of dough onto a parchment-lined baking sheet. Add a dollop of blueberry jam on top of each and swirl lightly.
Top with streusel
- Sprinkle the chilled streusel over each cookie.
Bake
- Bake at 375°F for 12-15 minutes, until lightly golden but still soft in the centers.
Cool and enjoy
- Allow the cookies to cool completely before serving.
Notes
Store leftover cookies in an airtight container at room temperature for up to a week. You can freeze them for up to three months and reheat to restore freshness.
