1️⃣ Prepare the Dough:
Whisk together flour, baking powder, and salt in a medium bowl. In a large bowl, beat butter and granulated sugar until light and fluffy. Mix in vanilla extract. Gradually add dry ingredients and mix until a soft dough forms.

2️⃣ Form the Cookies:
Scoop 1½ tablespoons of dough, roll into balls, and place on a parchment-lined baking sheet. Press a well into the center of each ball using your thumb or a small spoon.

3️⃣ Prepare the Crumble Topping:
In a small bowl, mix flour and brown sugar. Cut in cold butter until mixture resembles coarse crumbs.

4️⃣ Assemble the Cookies:
Fill each cookie well with about 1 teaspoon of raspberry jam. Sprinkle crumble topping over each cookie, covering both the jam and the edges.

5️⃣ Bake:
Preheat oven to 350°F (175°C). Bake for 14–16 minutes until edges are lightly golden. Let cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
