Marbled Chocolate Chunk Cookies are thick, chewy cookies with a twist of vanilla and chocolate. Chunks of creamy chocolate make these treats a real upgrade from regular chocolate chip cookies.

Why you'll love this recipe
Marbled Chocolate Chunk Cookies are a fun twist on standard chocolate chip cookies with only a minimum of extra effort. They are thick and chewy for days.
Freezing the dough balls before baking produces a slightly thicker cookie with less spread. This gives them a chewy texture with a longer shelf life, if they don’t get eaten first.Instructions
This is an overview of the instructions. The full instructions are in the recipe card below.

- In the bowl of an electric mixer, combine butter and sugars for about 2 minutes. Add eggs, one at a time, and vanilla. Beat until light and fluffy. Mix in flour mixture.
- Remove 1 ¾ cups of batter into another bowl.
- Stir the cocoa into the remaining batter in the mixer bowl. Then stir half of the chocolate chunks into the chocolate batter. Stir the rest of the chocolate chunks into the vanilla batter.

- When ready to bake: bake on a parchment lined cookie sheet at 350 degrees F until edges just begin to brown.

- 2 large eggs room temperature
- ¼ cup Dutch processed cocoa

Aha, this is very true! However, some of the cookies I`ve made, I stored them in an airtight container for over a week and they still taste great! These look wonderful!

Thanks, Lynna! Its all trial and error if a recipe gives you no indication at all of the shelf life. A tough job, but somebody has to do it. 🙂 If you would like to share any recipes you have found that stay fresh for over a week, please point me toward them. 🙂
