Preheat your oven to 350°F and line a baking sheet with parchment paper. Have all your ingredients measured and ready before you begin—this is especially important for cookie dough, which comes together quickly. I like to use room-temperature butter for these cookies because it creams more evenly and creates a better texture in the final cookies.

In a large mixing bowl, combine the softened butter, sugar, and vanilla extract. Beat on medium speed for about 1 minute until the mixture is light, fluffy, and well combined. This creaming step incorporates air into the dough, which helps the cookies rise slightly and gives them a tender crumb. Don't skip this—it makes a real difference in texture.

Add the all-purpose flour to the butter mixture and beat on medium speed for about 2 minutes. The dough will look crumbly and won't come together like typical cookie dough—this is exactly what you want. The texture should resemble coarse breadcrumbs or wet sand, which allows the dough to hold its shape around the cranberry filling without becoming tough.

Working with the crumbly dough from Step 3, form 1-inch balls and place them on your prepared baking sheet, spacing them about 1 inch apart. Use your thumb to gently press an indentation into the center of each ball, creating a small well. Fill each indentation with approximately 1/4 teaspoon of cranberry sauce—this is the perfect amount to stay contained during baking without overflowing. I find that slightly moistening my thumb helps prevent the dough from sticking as I shape each cookie.

Place the baking sheet in your preheated 350°F oven and bake for 15 minutes, or until the edges of the cookies turn light golden brown. The cookies won't look fully set in the center, and that's perfect—they'll continue to firm up as they cool. Watch for the edges to brown rather than waiting for the centers to look completely done, as this prevents overbaking and keeps the cookies tender.

Remove the baking sheet from the oven and let the cookies rest on the hot sheet for 2 minutes—this allows them to set slightly without cooling completely. Using a spatula, transfer the cookies to a wire cooling rack where they can cool completely. The cookies will firm up significantly as they cool to room temperature, developing their final texture and allowing the cranberry filling to set.
