Creating Buttery Raspberry Crumble Cookies is a straightforward process. Follow these simple steps for delicious results:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper for easy cleanup.
2. Cream Butter and Sugar: In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
3. Add Egg and Vanilla: Beat in the egg and vanilla extract until well combined.
4. Mix Dry Ingredients: In another bowl, whisk together the flour, baking powder, and salt.
5. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, mixing until just combined.
6. Prepare Crumble Topping: In a separate bowl, combine rolled oats, brown sugar, cinnamon, and the remaining butter. Mix until crumbly.
7. Assemble Cookies: Take a tablespoon of cookie dough and flatten it in your hand. Spoon a small amount of raspberry jam in the center and fold the dough around the jam, sealing it. Place on the prepared baking sheet.
8. Add Crumble Topping: Sprinkle the crumble topping generously over each cookie before baking.
9. Bake: Place the baking sheet in the preheated oven and bake for 15-20 minutes, or until the edges are lightly golden.
10. Cool: Allow the cookies to cool on the baking sheet for 10 minutes before transferring them to a wire rack to cool completely.
