1-First Step: Mix the dry ingredients In a medium bowl, whisk together the flour, baking soda, salt, espresso powder, and Vietnamese cinnamon. Mixing the dry ingredients first helps spread the spice and leavening evenly through the dough. That means every cookie will taste balanced instead of patchy. Set the bowl aside while you work on the wet ingredients.

2-Second Step: Cream the butter and sugars In a large mixing bowl, beat the butter, granulated sugar, dark brown sugar, and light brown sugar together until the mixture looks light and fluffy. This usually takes about 2 to 3 minutes with a hand mixer. If you are using browned butter, make sure it is fully cooled and solid enough to mix without turning greasy. This step helps create that soft center and lightly crisp edge that people love in chocolate chip cookies.

3-Third Step: Add the egg and vanilla Crack in the room temperature egg and pour in the vanilla extract. Beat again until everything looks smooth and well mixed. The egg brings the dough together, while the vanilla adds warmth and sweetness. A room temperature egg blends better into the butter mixture, so the dough stays smooth and easy to scoop.

4-Fourth Step: Combine wet and dry mixtures Slowly add the dry ingredients into the wet bowl. Mix on low speed or stir by hand just until the flour disappears. Do not overmix, or the cookies may turn dense instead of soft. At this stage, the dough should look thick and slightly sticky, which is exactly what you want.

5-Fifth Step: Fold in the chocolate chips Add the dark chocolate chips and fold them through the dough with a spatula. Make sure the chips are spread evenly so each cookie gets a good amount of chocolate. If you want extra chocolate flavor, you can press a few chips on top of each dough ball before baking.

6-Sixth Step: Chill the dough For the best texture, cover the bowl and chill the dough for at least 30 minutes. If you have more time, 24 hours in the refrigerator gives even better flavor and a thicker cookie. Chilling helps the butter firm up, which keeps the cookies from spreading too much in the oven. It also gives the Vietnamese cinnamon time to blend into the dough.

7-Seventh Step: Shape and bake Scoop the dough into rounded tablespoons and place them about 2 inches apart on the prepared baking sheets. If you want extra neat cookies, use a cookie scoop for even portions. Bake for 10 to 12 minutes, or until the edges look set and lightly golden while the centers still look a little soft. This helps the cookies stay chewy once they cool.

8-Eighth Step: Cool before moving Let the cookies sit on the baking sheet for 10 minutes before moving them to a wire rack. This resting time helps them finish setting without breaking apart. The centers will firm up as they cool, and the flavor of the cinnamon and chocolate will settle in beautifully. If you move them too soon, they may fall apart.

9-Final Step: Serve and enjoy Once fully cooled, serve the cookies with milk, coffee, or tea. They taste fantastic warm, but they also hold up well for storage and lunchbox snacks. If you want a fun pairing idea, try serving them after a light breakfast like mini muffin pancake bites for a family brunch or alongside a simple fruit smoothie. These cookies are the kind of treat that disappears fast, so you may want to make a double batch.
