Small Batch Sugar Cookies

Preheat the oven to 350, and line a small baking sheet with parchment paper (or use a silicone mat).

Stir together the melted butter, sugar, egg yolk, and vanilla extract. Stir very well to combine.

Next, sprinkle the flour, baking soda and salt evenly over the dough, and stir just to combine.

Press the dough flat and evenly in the bowl, and then divide it in half by eye. You should get 3 cookies from each half.

Roll each dough ball in your hands, roll lightly extra granulated sugar, and then space evenly on the prepared baking sheet.

Bake for 10-12 minutes, until they spread, start to crackle and appear dry on top.

Let the cookies rest on the baking sheet for 2 minutes before moving them to a wire rack to cool completely.

After the cookies have cooled for 10 minutes, press a chocolate heart into the center of each cookie. Move the cookies to the fridge (so the hearts don't melt too much) to set for 30 minutes.

Bring to room temperature before serving.
