1. Make the Crumble Topping:
- Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat.
- In a small bowl, combine flour, brown sugar, and cinnamon. Drizzle melted butter over the mixture and mix with a fork until crumbly.
- Spread the crumble topping onto the prepared baking sheet and bake for 10 minutes until golden brown.
- Remove from the oven and set aside. Turn off the oven for now; preheat again 10 minutes before baking cookies.
2. Make the Cookie Dough:
- In a medium mixing bowl, whisk together flour, salt, baking soda, and baking powder. Set aside.
- In the bowl of a stand mixer fitted with a paddle attachment, beat the butter and sugars on medium-high speed (6-8 on a stand mixer) for 3-5 minutes until light and fluffy.
- Add the egg and vanilla, beating on medium speed until well combined.
- Scrape down the bowl, then add the flour mixture in three batches, mixing on low and gradually increasing to medium speed. Mix until no streaks of dry flour remain.
- Fold in ¾ cup of diced strawberries until evenly distributed.
3. Chill the Dough:
- Cover the bowl tightly with plastic wrap and refrigerate the dough for at least 1 hour or overnight for best results.
4. Bake the Cookies:
- Preheat the oven to 350°F (175°C). Line baking sheets with parchment paper or silicone mats.
- Use a 1-tablespoon cookie scoop to portion dough, placing cookies about 2 inches apart on the prepared sheets.
- Bake for 9-12 minutes, or until edges are golden and centers are slightly gooey.
5. Add Toppings:
- Top freshly baked cookies with 2-3 more strawberry pieces and a sprinkle of crumble topping.
- Allow cookies to cool on the baking sheet for 10 minutes before transferring them to a wire rack to cool completely.
Tips for Success:
- Storage: Store cookies in an airtight container at room temperature for up to 3 days.
- Freezing: Freeze unbaked cookie dough balls for up to 3 months. Bake directly from frozen, adding 1-2 minutes to the baking time.
- Freshness: Use ripe but firm strawberries for the best flavor and texture.
These cookies are a celebration of summer flavors and the perfect blend of soft, sweet, and crumbly textures. 🍓💖
