1-First Step: Preheat your oven to 350°F (175°C). Line a small baking sheet with parchment paper. This setup prevents sticking and ensures even baking for your single serving chocolate chip cookie.

2-Second Step: In a small bowl, cream 1 tablespoon softened butter with 2 tablespoons brown sugar and 1 tablespoon granulated sugar. Use a fork to mash until smooth and fluffy, about 1 minute. Add a pinch of salt, 1/4 teaspoon vanilla extract, and 1 egg yolk. Stir vigorously until fully combined. This creaming builds the cookie’s signature texture.

3-Third Step: Fold in 3 tablespoons all-purpose flour and 1/8 teaspoon baking soda. Mix gently to avoid overworking the dough. Stir in 2 tablespoons semi-sweet chocolate chips. The dough will be sticky but scoopable, perfect for one cookie.

4-Fourth Step: Shape the dough into a 3-inch round on the prepared sheet. Use your hands to flatten slightly for even cooking. For dietary needs, this is where you add gluten-free flour or vegan swaps seamlessly.

5-Final Step: Bake for 10-12 minutes until edges turn golden. Cool on the sheet for 5 minutes the center stays soft while edges crisp. Enjoy warm for peak flavor. Total time: 15-20 minutes.

6-First Step: Select a microwave-safe mug. Melt 1 tablespoon butter in it for 10 seconds. This quick single serving cookie recipe starts fast.

7-Second Step: Stir in 2 tablespoons brown sugar, 1 tablespoon white sugar, pinch salt, 1/4 teaspoon vanilla, and 1 egg yolk. Whisk until smooth, 30 seconds.

8-Third Step: Add 3 tablespoons flour, 1/8 teaspoon baking soda, and 2 tablespoons chocolate chips. Mix to form thick batter. Adapt here for low-calorie by using applesauce.
