Introduction
Sometimes you don’t need a full batch of cookies, just a perfectly warm, fresh-baked treat made for sharing—or not. This recipe yields two bakery-style, chewy-centered cookies with crispy edges, delivering maximum satisfaction with zero leftovers.
Prep & Cook Time
Prep Time: 7 minutes
Cook Time: 13 minutes
Total Time: 20 minutes
Servings: 2
Ingredients
- 3 Tbsp unsalted butter (mostly, but not fully melted)
- 3 Tbsp light brown sugar (lightly packed)
- 1 Tbsp granulated sugar
- 1 large egg yolk
- 3/4 tsp pure vanilla extract
- 1/2 cup all-purpose flour
- 1 Tbsp cornstarch
- 1/8 tsp baking soda
- 1/8 tsp salt
- 6 Tbsp semi-sweet chocolate chips (divided)
Instructions
- Preheat your oven to 350°F (175°C). Line a small baking sheet with parchment paper.
- In a medium bowl, whisk together the mostly melted butter, light brown sugar, and granulated sugar until smooth.
- Add the egg yolk and vanilla extract to the sugar-butter mixture, and whisk vigorously until well combined and slightly thickened.
- In a separate small bowl, whisk together the flour, cornstarch, baking soda, and salt.
- Add the dry ingredients to the wet ingredients, mixing with a spatula just until a few flour streaks remain.
- Fold in 3 Tbsp of the chocolate chips.
- Scoop the dough into two equal portions (each will be roughly the size of a golf ball). Place them on the prepared baking sheet, spacing them at least 3 inches apart as they will spread.
- Gently press the remaining 3 Tbsp of chocolate chips onto the tops of the dough balls.
- Bake for 11-13 minutes, until the edges are set and golden and the centers look just barely underdone.
- Remove from the oven and let the cookies cool on the baking sheet for at least 10 minutes to finish setting up.
Variations
- Brookie-Style: Flatten the cookie dough balls slightly and press a small square of brownie batter (from a box mix) into the center before baking.
- Pan Cookie: Press all the dough into a small, greased oven-safe skillet and bake for 15-18 minutes for a single, shareable skillet cookie.
- Stuffed Cookie: Flatten each dough ball and sandwich a small piece of a chocolate bar or a marshmallow in the center, sealing the dough around it before baking.
- Salted Caramel Puddle: Right after baking, press the back of a spoon into the center of each warm cookie and fill the indent with a dollop of caramel sauce.
Tips for Success
- For the best texture, ensure your butter is *mostly* melted but still slightly soft, not hot. This helps create the perfect chewy-crispy balance.
- Using a kitchen scale to measure the flour (62g) is more accurate than cup measurements for consistent results.
- The cookies will look underdone when you take them out. They will finish cooking on the hot baking sheet, so patience during cooling is key for a perfect texture.
Storage & Reheating
Store any leftover cookies in an airtight container at room temperature for up to 2 days. To reheat and restore that fresh-baked feel, microwave a cookie for 8-10 seconds or warm it in a 300°F oven for 3-4 minutes.
FAQ
Why use mostly melted butter?
Mostly melted butter (with a few soft pieces) helps the cookies spread properly without requiring a long creaming process. It contributes to a chewy interior and a crispier edge.
Can I use a whole egg instead of just a yolk?
No, the egg yolk adds richness without the extra moisture from the white, which would make the cookies cakey. Save the white for breakfast or a cocktail.
My cookies spread too much. What happened?
This can happen if the butter was too warm/hot, or if your baking soda is old and inactive. Ensure your butter is just mostly melted, not piping hot, and check your leavener’s date.
Can I make the dough ahead and bake later?
Yes, you can scoop the dough balls onto a plate, cover tightly, and refrigerate for up to 48 hours. Let them sit at room temperature for 10 minutes before baking.
Why is cornstarch included?
The cornstarch (a substitute for a full amount of flour) makes the cookies extra soft and tender by inhibiting gluten development.
Can I double this recipe?
Absolutely! For a standard batch of 4 cookies, simply double all ingredients and follow the same instructions.
