I stumbled upon these marble cookies while experimenting in my kitchen and they've become my signature bake. Every swirl of chocolate and vanilla creates this beautiful pattern that's completely unique to each cookie. They're chewy soft in the middle with perfectly crisp edges just the way a great cookie should be.
What Makes These Extra Special
The magic happens when you bite into these cookies. That perfect mix of chocolate and vanilla dough gives you two flavors in every bite. My family can never wait for them to cool they disappear right off the cooling rack. Plus they look so fancy everyone thinks you spent hours making them.

Fun Ways to Mix It Up
Some days I toss in chopped pecans for crunch. White chocolate chips create these lovely creamy bites through the marbled dough. When I'm feeling fancy I use dark cocoa powder it makes the chocolate swirls extra rich. During the holidays I love adding dried cranberries they look like little jewels in the cookies.
Perfect Partners
These cookies and cold milk were made for each other. I love dunking them in my morning coffee too. Whenever I bring them to parties or cookie exchanges they're always the first to go. Something about those swirls just draws everyone in.

Frequently Asked Questions
- → Why chill the dough?
Chilling for at least an hour prevents spreading and deepens flavors. Cold dough keeps cookies thick and chewy.
- → How do I get the best marble effect?
Fold doughs together gently without overmixing. Light folding keeps chocolate and vanilla swirls distinct.
- → Can I freeze these cookies?
Freeze baked cookies up to 3 months or freeze dough balls to bake later. Add 1-2 minutes to baking time if baking from frozen.
- → How do I know when they're done?
Edges should be set but centers still soft at 10-12 minutes. They'll continue setting as they cool.
- → Can I use milk chocolate chips?
Any chocolate chips work well. Try semi-sweet, milk, or dark chocolate based on your preference.
