Preheat the oven to 350 degrees F. Line two baking sheets with parchment paper.

In a large bowl using an electric mixer, cream together the butter and sugar until light and fluffy. Add in the egg and mix well.

Blend in the baking powder, salt, and flour until just combined. Mix in the graham cracker crumbs.

Scoop 3 tablespoons of dough and form it into a ball. Place each ball onto the prepared baking sheet and press down slightly with the bottom of a glass. Then use your thumb to make a deep indention in the middle of each cookie.

In a small bowl using an electric mixer, make the cheesecake filling by blending together the cream cheese, sugar, egg white, and vanilla extract. Spoon two teaspoons of the filling into the indention in each cookie. Top with 1/2 teaspoon of strawberry jam then use a toothpick to swirl together.

Bake for 10-12 minutes until golden brown around the edges. Cool completely before serving.
