Ingredients

• 200g (about 1 cup) of unsalted butter, softened
• 150g (about 3/4 cup) of granulated sugar
• 1 large egg
• 1 teaspoon of vanilla extract
• 300g (about 2 1/2 cups) of all-purpose flour
• 100g (about 1/2 cup) of fruit jam (your choice)
• A pinch of salt

Instructions

1. Preheat your oven to 180°C (350°F).
2. In a large bowl, cream the softened butter and sugar together until light and fluffy.
3. Add the egg and vanilla extract, mixing well to combine.
4. Gradually add the flour and salt, stirring until the dough comes together.
5. On a floured surface, roll out the dough to about 1/4 inch thick.
6. Use cookie cutters to cut out shapes, and place half of the cookies on a baking sheet lined with parchment paper.
7. Make a small hole in the center of the remaining cookies to create windows for the jam filling.
8. Spoon a small amount of jam into the center of each cookie with a hole.
9. Top the jam-filled cookies with the cut-out cookies, pressing slightly to seal.
10. Bake for 10-12 minutes, or until lightly golden.
11. Allow the cookies to cool completely before serving.
