Equipment
- Mixing bowls (large and medium)
- Stand mixer or hand mixer
- Measuring cups and spoons
- Rubber spatula or wooden spoon
- Baking sheets
- Parchment paper or silicone baking mats
- Cookie scoop (3 Tbsp size for jumbo cookies)
- Wire cooling rack
Ingredients
- ½ cup salted butter (113 g)
- ½ cup brown sugar (100 g)
- ¼ cup granulated sugar (50 g)
- 1 large egg
- 3 Tbsp light corn syrup
- ½ Tbsp molasses
- ¼ tsp vanilla extract
- 1 ¾ cups all‑purpose flour (220 g)
- ¼ tsp salt
- ¼ tsp baking soda
- ¾ cup chocolate chunks (130 g)
Instructions
- Preheat the oven: Set your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat.
- Cream the butter and sugars: In a stand mixer or with a hand mixer, beat the softened butter, brown sugar, and granulated sugar until pale and fluffy.
- Add wet ingredients: Scrape down the bowl, then mix in the egg, corn syrup, molasses, and vanilla until smooth and well blended.
- Incorporate dry ingredients: Add the flour, salt, and baking soda. Mix on low speed until a sticky dough forms—don’t overmix.
- Fold in chocolate chunks: Stir in the chocolate chunks with a spatula, making sure they’re evenly distributed throughout the dough.
- Shape the cookies: Scoop about 3 tablespoons of dough per cookie, roll into balls, and place on the prepared baking sheet. Press a few extra chocolate chunks on top if desired.
- Bake and cool: Bake for 9–11 minutes, until the edges are golden and the centers look slightly underdone. Let cookies cool on the pan before transferring to a wire rack.
