Step 1

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. This helps prevent sticking and makes cleanup a breeze.

Step 2

In a large mixing bowl, cream together the softened butter and granulated sugar until it becomes light and fluffy, about 2-3 minutes. Add in the egg and vanilla extract, mixing until fully incorporated.

Step 3

In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add this flour mixture to the creamed butter mixture, mixing until a soft dough forms. Be careful not to overmix, as this can make the cookies tough instead of tender.

Step 4

In a small bowl, beat together the softened cream cheese and powdered sugar until smooth and creamy. Add a spoonful of strawberry jam and swirl it in gently to create a marbled effect.

Step 5

Take a tablespoon-sized portion of the cookie dough and flatten it into a round shape on the prepared baking sheet. Spoon a small amount of the cream cheese filling and strawberry jam swirl onto the center of each dough round.

Step 6

In another bowl, combine the flour and sugar for the crumble topping. Add the cold, cubed butter and use a fork or your fingers to mix until the texture is crumbly. Sprinkle this mixture over each cookie for an extra layer of flavor and texture.

Step 7

Bake the cookies for 12-15 minutes or until the edges turn a light golden brown. Let them cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
