In a large mixing bowl, or the bowl of your stand mixer, beat the butter until it is smooth and creamy.
Add the cream cheese and beat until combined and lump free.
Mix in the sugar until light and fluffy.
Stir in the flour until just incorporated. It is okay if the dough is a bit sticky.
Chill for at least 45 minutes, but up to 2 hours. While the dough is chilling, preheat the oven to 375℉.
Line baking sheets with parchment paper or silicone baking mats.
Use a small cookie scoop to scoop 1 Tablespoon of dough onto the prepared cookie sheet. Roll the ball between your hands to form smooth balls. Place at least an inch apart on the pan.
Use your thumb to put an indent in the center of each of the dough balls. Fill each indentation with about ½ teaspoon of jam.
Bake 11-12 minutes. The cookies should be slightly puffed and look mostly set. There may be a light golden brown around the edges, but they shouldn't have much color.
Cool on the pan for 10 minutes, then move to a wire rack to cool completely.
