Soft, chewy oatmeal cookies with a sweet pop of jam in the center. These oatmeal thumbprint cookies are simple to make, endlessly adaptable, and perfect for gifting or sharing.
Preheat oven to 350°F (175°C). Line baking sheets with parchment paper or silicone liners.
Whisk together the flour, baking soda, cinnamon, and salt. Set aside.
Using an electric mixer on medium speed, beat the butter and both sugars until light and fluffy. Add the eggs, one at a time, mixing well after each addition. Mix in the vanilla.
With the mixer on low speed, gradually add the flour mixture, mixing until fully incorporated. Mix in the oats.
Using a tablespoon of dough (#60 scoop) at a time, roll the dough into balls and place onto the prepared pans, placing them about 2 inches apart. Using your thumb, make a hollow in each cookie. Fill each hollow with jam or preserves.
Bake one pan at a time for 12-14 minutes, or until cookies are fully baked and the edges are golden.

Notes
Recipe adapted from The Treats Truck Baking Book.
Oats: Use old-fashioned rolled oats for the best chewy texture. Quick oats will make the cookies softer and less hearty.
Jam: Any smooth jam or preserve works well. Thicker jams hold their shape best during baking.
Chilling: If the dough feels too soft to roll, chill it for about 20–30 minutes before shaping.
Jam filling: Don’t overfill the indentations. About ½ teaspoon per cookie is plenty.
Freezing: Baked cookies freeze well for up to 3 months. Freeze unbaked dough balls (without jam) for make-ahead convenience.
