These 3-Ingredient Coconut Thumbprint Cookies are the easiest holiday treat—naturally gluten-free, egg-free, and ready in minutes. Chewy, toasty coconut and sweet jam make them festive, pretty, and perfect for cookie swaps.
Preheat the oven to 350°F (175°C). Line two large baking sheets with parchment paper.
In a large bowl, stir together the shredded coconut and sweetened condensed milk until the coconut is fully incorporated and coated.
Use a 1 tablespoon cookie scoop to scoop the dough. With lightly wet hands, roll each portion into a smooth ball. Place the balls on the prepared baking sheets, spacing about 2 inches apart.
Use your thumb or the back of a 1 teaspoon measuring spoon to gently press an indent into the center of each ball. Your cookie should look like a thick round disk with a large indent in the center (see photo for reference).
Fill each indent with about 1 scant teaspoon of jam. Bake for 13–15 minutes, or until the edges are golden brown.
Let cool completely on the baking sheet before removing. Store uneaten cookies in an airtight container for 1-2 days at room temperature and longer in the fridge or freezer.
