To whip up these irresistible cookies, you’ll need a handful of simple pantry staples and fresh blueberries for that burst of fruity goodness.
Baking these cookies is a breeze once your ingredients are prepped. You’ll start by preheating the oven, then whisk together the dry mix while creaming your butter and sugars. After blending in the wet ingredients, gently fold in those juicy blueberries and prepare a simple streusel. Finally, scoop the dough, top with streusel, and watch them bake to golden perfection. Here’s the step-by-step:
1. Preheat the oven to 350°F and line two baking sheets with parchment paper for easy cleanup and even baking.
2. In a medium bowl, whisk together 2 cups flour, baking powder, baking soda, and 1/2 teaspoon salt; set aside to distribute the leaveners evenly.
3. In a large bowl, cream together 1/2 cup softened butter, granulated sugar, and brown sugar until light and fluffy, about 2–3 minutes.
4. Beat in the egg, vanilla extract, and sour cream until fully combined and smooth.
5. Gradually add the dry ingredients to the wet mixture and stir until just combined—avoid overmixing to keep the cookies tender.
6. Gently fold in the fresh blueberries, taking care not to burst them and turn your dough purple.
7. In a small bowl, combine 1/3 cup flour, 3 tablespoons granulated sugar, and a pinch of salt; cut in the cold cubed butter with a fork until the mixture resembles coarse crumbs.
8. Scoop rounded tablespoonfuls of dough onto the prepared sheets, spacing them 2 inches apart for even spreading.
9. Generously sprinkle the streusel topping over each cookie mound, covering the dough completely.
10. Bake for 12 to 15 minutes or until the edges are set and the tops are lightly golden and crisp.
11. Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Keeping your cookies fresh and flavorful is key to enjoying them day after day. Whether you plan to bake in advance or save leftovers, here’s how:
Here are some quick answers to your most common questions:
A: Preparing the dough and streusel takes about 20 minutes, including measuring ingredients, creaming butter and sugars, whisking the dry mix, and folding in blueberries. Baking requires 12 to 15 minutes at 350°F. Allow an additional 5 minutes cooling on the baking sheet and a few more minutes on a wire rack before serving, for a total time of roughly 40 minutes.
A: You can use frozen blueberries, but do not thaw them before mixing to prevent their juices from bleeding into the dough. Gently fold the berries straight from the freezer into the batter; the cold berries will help keep the dough firm and prevent color bleeding. You may need to add an extra minute or two to baking time if the dough is very cold.
A: Combine 1/3 cup flour, 3 tablespoons granulated sugar, a pinch of salt, and the cold cubed butter. Cut in with a fork until you have coarse crumbs. Store the streusel in an airtight container in the refrigerator for up to 24 hours. Sprinkle it over the cookie dough just before baking to ensure it bakes into crisp, golden crumbs.
A: Yes. Use an equal amount of full-fat Greek yogurt in place of the 1/2 cup sour cream for a tangier flavor. Because Greek yogurt can be thicker, you may need to stir it to a smooth consistency or add a teaspoon of milk if it’s very stiff to match the texture of sour cream.
A: Once the cookies have cooled completely, place them in an airtight container at room temperature. They will stay fresh for up to three days. To maintain the crunch of the streusel, layer cookies between sheets of parchment or wax paper to prevent them from sticking together.
A: Yes. For dough: scoop rounded tablespoonfuls onto a parchment-lined baking sheet, freeze until solid (about 1 hour), then transfer to a freezer bag. Bake from frozen, adding 1–2 minutes to the baking time at 350°F. For baked cookies: cool completely, then freeze in a sealed container or freezer bag for up to one month. Thaw at room temperature for 30 minutes before serving.
A: The cookies are done when their edges are set and firm, the tops are lightly golden, and the centers spring back slightly when touched. The streusel topping should look crisp and golden but not burnt. Avoid overbaking to keep the centers tender and muffin-like.
What really sets these cookies apart is the best-of-both-worlds magic: a tender, muffin-style crumb studded with vibrant blueberries, finished off with a delightfully crunchy streusel.
