Make sure the butter is softened to room temperature, or it may not mix properly.
Be sure to sift the flour before mixing it into the dough, as it helps the dough come together better.
Feel free to use any cookie cutter shape you prefer for the center cutout. I used a heart, but a star or flower would also look adorable.
Work quickly when rolling out the dough and cutting it with cookie cutters, as the dough tends to soften due to its high butter content. If needed, add more flour to prevent sticking.
You can use any flavor of jam you like for these cookies. While I used strawberry jam, raspberry, orange, fig, cherry, apricot—really any flavor works!
