Chocolate chips, white chocolate chips and unsweetened cocoa powder come together to make a delightfully fudgy, brownie-like cookie. These cookies are rich but not overly sweet, generously sized (perfect for sharing), and take roughly 30 minutes from start to finish.
If you like variety in your cookies, give these a try. For a more classic option, consider traditional chocolate chip cookies instead.

Thick and Chewy White Chocolate Cookies
These cookies were developed while experimenting with variations on the classic chocolate chip cookie. The goal was a deeply chocolatey base balanced by the sweet contrast of white chocolate, and a thick, chewy texture. The batter will be very thick — that’s expected and what creates the dense, fudgy interior.


High-quality cocoa makes better chocolate cookies
Using a quality cocoa powder and good chocolate for the chips or chopped baking bars makes a noticeable difference. I prefer richer cocoa and decent chocolate chips to avoid any artificial or flat flavors in the finished cookie.
Dark brown sugar is my preference here for its deeper, more complex flavor. I portion these cookies on the generous side — about two ounces of dough per cookie — which yields a substantial cookie in a single serving. You can make smaller cookies if you prefer; just reduce baking time slightly. Weighing dough portions helps ensure even baking and consistent sizes.

Substitutions for white chocolate
If you’re not a fan of white chocolate, swap the white chocolate chips for an equal amount of semi-sweet chips, chopped dark chocolate, or chopped nuts such as walnuts. Toffee bits also work well. I don’t recommend omitting the mix-ins entirely, as they contribute to the cookie’s texture and overall balance.
Enjoy these cookies! If you want more easy cookie ideas, try other recipes like oatmeal cookies, cereal-based cookies, or simple sugar cookie bars.
