Two-Chip Bakery Cookies with Crispy Edges and Gooey Centers Step-by-step instructions

Before you start

Before starting, take the butter out of the refrigerator and let it soften at room temperature for about 30 minutes. Measure all ingredients accurately: for the flour, spoon it into the measuring cup and level it off with a knife.

Line two baking sheets with parchment paper and preheat the oven to 375°F (190°C). Have your stand mixer or hand mixer ready, along with a large mixing bowl, a whisk, and a rubber spatula. If your chocolate chunks are large, chop them into smaller, bite-sized pieces so they distribute evenly.

Instructions

Creaming and Mixing

1. 1Cream Butter and Sugars
   In a large mixing bowl, beat the softened butter with the dark brown sugar and granulated sugar until the mixture is light and fluffy, about 2 to 3 minutes. Add the cold eggs one at a time, beating well after each addition, then beat in the vanilla bean extract until fully incorporated.
   Look for The mixture should look pale, airy, and slightly increased in volume.
   Tip Make sure the butter is truly softened to room temperature for the best creaming.
2. 2Combine Dry Ingredients
   In a separate bowl, whisk together the all-purpose flour, baking soda, and cornstarch until well blended. This ensures the leavening and thickener are evenly distributed throughout the dough.
   Look for The dry mixture should look uniform with no visible clumps of baking soda.
   Tip Sifting the flour is optional but helps aerate the mixture for a lighter texture.
3. 3Fold in Dry Ingredients
   Gradually add the dry ingredients to the butter mixture, mixing on low speed or folding with a spatula until just combined. Be careful not to overmix, as this can develop gluten and make the cookies tough.
   Look for The dough should come together with no dry streaks of flour visible.
   Tip Stop mixing as soon as the flour disappears to keep the cookies tender.
4. 4Add Both Chocolates
   Gently fold in the milk chocolate chips and dark chocolate chunks with a rubber spatula. Make sure they are evenly distributed throughout the dough, but avoid overworking the dough.
   Look for The dough should be studded with chocolate in every bite.
   Tip Reserve a few chocolate pieces to press on top of each cookie before baking for a prettier look.

At the end of this phase, the butter-sugar mixture should be pale, light, and fluffy, with no visible granules of sugar. The dry ingredients should be fully incorporated into a cohesive dough, and the chocolate chips and chunks should be evenly distributed.

The dough should hold together when pressed but not be overly sticky. If it is, refrigerate briefly. This phase sets the foundation for the cookie's texture, so take care not to overmix.

Scooping and Baking

5. 5Scoop Dough Balls
   Using a large cookie scoop or spoon, scoop the dough into generous balls, about 2 to 3 tablespoons each. Place them on parchment-lined baking sheets, spacing them at least 2 inches apart to allow for spreading.
   Look for The dough balls should be uniform in size for even baking.
   Tip Chill the dough for 30 minutes if it feels too soft to handle, but this is optional.
6. 6Bake the Cookies
   Bake the cookies in a preheated oven at 375°F (190°C) for 11 minutes, or until the edges are golden brown and caramelized. The centers will look slightly underdone but will continue to set as they cool.
   Look for The edges should be crisp and deeply golden, while the centers look slightly puffed and moist.

   Tip Rotate the baking sheets halfway through baking for even browning.
7. 7Finish with Sea Salt
   Immediately after removing the cookies from the oven, sprinkle each with a pinch of flaky sea salt. The salt enhances the chocolate flavor and balances the sweetness.
   Look for The salt crystals should be visible on the surface of the warm cookies.
   Tip Sprinkle the salt while the cookies are still warm so it adheres.

The dough balls should be uniform in size, about 2 to 3 tablespoons each, and spaced well apart on the baking sheets. As they bake, the edges will begin to caramelize and turn golden, while the centers remain puffy and soft. The kitchen will smell of butter and chocolate. When the edges are deeply golden and the centers look slightly glossy, the cookies are ready to come out. The flaky sea salt should be sprinkled on immediately after baking.

Cooling and Setting

8. 8Cool on Baking Sheets
   Let the cookies cool on the baking sheets for 5 minutes. This allows them to set slightly without over-baking, and makes them easier to transfer without breaking.
   Look for The cookies should be firm enough to lift with a spatula but still soft in the center.
   Tip Do not skip this rest—it helps the centers stay gooey.
9. 9Transfer to Wire Rack
   Transfer the cookies to a wire rack to cool completely. If you prefer warm, gooey cookies, enjoy them after a few minutes of cooling. For fully set cookies, let them cool completely.
   Look for The cookies should be slightly crisp on the edges and soft in the middle.
   Tip For the classic bakery experience, serve warm with a glass of milk.

After the cookies rest on the baking sheet for 5 minutes, they should be firm enough to move without breaking, but still soft in the center. Transferring them to a wire rack allows air to circulate, preventing soggy bottoms. The cookies will continue to set as they cool, with the edges becoming crisp and the centers remaining tender and gooey. If serving warm, enjoy within 10 minutes for the ultimate molten chocolate experience.

Common mistakes

One common mistake is overmixing the dough after adding the flour, which develops gluten and results in tough, dense cookies. Mix only until the flour is just incorporated.

Another issue is overbaking: because the centers continue to cook from residual heat, it's crucial to pull the cookies out when the edges are golden but the centers still look slightly underdone. Also, be sure to space the dough balls at least 2 inches apart, as they spread during baking. Finally, don't skip the flaky sea salt—it's a key flavor enhancer.

How to tell it’s done

The cookies are done when the edges are deeply golden and caramelized, and the centers look slightly puffed and moist, with a matte surface. The internal temperature of the cookies should reach at least 160°F (71°C) to ensure the eggs are fully cooked.

While the centers will still be soft and gooey, they will set as they cool. For a more precise check, insert an instant-read thermometer into the center of a cookie—it should read 160°F (71°C) or higher. If the edges are browning too quickly, reduce the oven temperature slightly.
