Two-Chip Chocolate Chip Cookies

Ingredients

Ingredient notes & substitutions

Cold eggs:

Straight from the fridge, cold eggs shock the creamed butter and help the dough hold its shape instead of spreading thin.

Slightly softened butter:

You want it pliable but still cool to the touch — fully melted or overly soft butter will give you flat, greasy cookies.

Cornstarch:

A small amount here softens the crumb and adds to that thick, bakery-style bite without changing the flavor.

Dark brown sugar:

The extra molasses in dark brown sugar (versus light) gives these a deeper caramel flavor and keeps them moist longer.

Semi-sweet and dark chocolate chips:

Using two types adds contrast — semi-sweet for classic sweetness, dark for a bittersweet edge; swap in chopped chocolate bars for extra melty puddles.

Baking powder and baking soda together:

This combo gives lift and thickness while still encouraging some spread and browning on the edges.

Method

1. 1

   Preheat the oven to 350°F (180°C) and line a baking sheet with parchment.

2. 2

   Whisk the flour, baking powder, baking soda and cornstarch in a medium bowl. Set aside.

   
3. 3

   Cream the brown sugar, granulated sugar and butter in a large bowl until light and fluffy.

4. 4

   Beat in the eggs one at a time, then the vanilla, for 3–4 minutes until the batter turns pale and the sugar is fully incorporated.

5. 5

   Gradually mix in the dry ingredients and salt until just combined — don't overmix.

   
6. 6

   Stir in both chocolate chips.

7. 7

   Scoop large balls of dough onto the tray, leaving them rough and stacked for a rustic craggy top. Place only 4 per pan with 4 inches between them, and press extra chips on top.

8. 8

   Bake 13–16 minutes on the middle rack until the edges are lightly golden but the centers still look soft.

9. 9

   Cool on the tray for 5 minutes before moving to a wire rack — they finish setting as they cool.

   

Variations to try

• Swap half the dark chips for chopped walnuts or pecans for crunch against the gooey centers
• Use all dark chocolate chips (no semi-sweet) for a deeper, less sweet cookie
• Add 1/2 tsp espresso powder with the dry ingredients to intensify the chocolate flavor
• Finish with a sprinkle of flaky sea salt right after baking for a sweet-salty contrast

Storage & make-ahead

Store cooled cookies in an airtight container at room temperature for up to 4 days — they'll stay soft since the brown sugar keeps them moist. To make ahead, scoop the rough dough balls onto a tray, freeze until solid, then transfer to a freezer bag for up to 3 months; bake straight from frozen, adding 2-3 extra minutes. Baked cookies also freeze well for up to 2 months; thaw at room temperature or warm in a 300°F oven for a few minutes to bring back that just-baked gooeyness.

Frequently asked questions

Why did my cookies spread out flat instead of staying thick?

Your butter was likely too soft or melted, or your eggs weren't cold enough — both cause the dough to spread before it sets. Also double-check your baking soda and baking powder are fresh, since old leavening won't give the dough enough lift.

Can I chill the dough anyway if I want to prep ahead?

Yes, this dough handles a chill fine even though it's not required — just let it sit at room temperature for 10-15 minutes before scooping so it's easier to shape into those rough, stacked balls.

How do I know when to pull them out of the oven?

Look for lightly golden edges while the centers still look pale, soft, and slightly underdone — they'll firm up as they cool on the tray for those 5 minutes, so resist the urge to bake them longer.

Can I make these smaller for a bigger batch?

You can, but you'll lose some of the thick, bakery-style effect — if you scoop smaller, reduce the bake time by 2-3 minutes and check them a little earlier since smaller dough balls set faster.
