Black and White Cookie Bars

Chocolate and vanilla cookies get all mixed up in these Black and White Cookie Bars! - Bake or Break

I bake a lot of cookies. One glance at BoB’s recipe index will show you that pretty quickly. I bake so many, in fact, that I have a container in my kitchen dedicated solely to cookie scoops of various sizes. Occupational hazard, I suppose. But still… so many cookies.

I’m also a fan of simplicity. And I’m honest enough to admit that there are times when I want to bake cookies but really don’t want to scoop them and then bake one pan after another. That’s where these cookie bars come into the picture.

You will still get to enjoy freshly baked cookies, but you’ll just need one pan. After they’re baked, simply cut them into bars and enjoy. Think of them as lazy cookies, if you like. Or just pride yourself on your time-saving baking skills.

Now you may be looking at the two different colors in these bars and thinking that will complicate things. Oh, but it doesn’t. Just mix up the vanilla dough and then drop about half of it into the baking pan. Add some chocolate to the remaining dough (in the same mixing bowl, even!) to transform it into chocolate cookie dough. Fill in the gaps in the pan with the chocolate dough, and there you go. Done.

You don’t need to worry about spreading the dough smoothly on top. It will all spread and even out while it bakes. And if they have an uneven terrain when they’re done, that just makes them all the more interesting.

Swirling is not my strong suit, but luckily these bars don’t require any great swirling techniques. Instead, the two doughs are simply scooped into the baking pan. Make a repeating pattern if you like, or take my approach and just make a random pattern and see what happens. I like to use a random pattern so that some of the bars will be a bit more chocolate while others will be a bit more vanilla. Whatever pattern you make, I think you’ll love this chocolate-vanilla flavor mash-up!

Black and White Cookie Bars

Yield 24 2-inch bars
Prep Time 25 minutes
Cook Time 35 minutes

Ingredients

  • 3 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 1 & 1/4 cups unsalted butter, softened
  • 1 & 1/2 cups granulated sugar
  • 3/4 cup firmly packed light brown sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 4 ounces bittersweet chocolate, melted and slightly cooled

Instructions

  1. Preheat oven to 350°. Grease a 9”x 13” baking pan.
  2. Whisk together flour, baking powder, and salt. Set aside.
  3. Using an electric mixer on medium speed, beat the butter, sugar, and brown sugar until light and fluffy. Add the eggs, one at a time, mixing well after each addition. Mix in the vanilla.
  4. Reduce mixer speed to low. Gradually add the flour mixture, mixing just until combined.
  5. Drop slightly more than half the batter by tablespoonfuls into the prepared pan, leaving gaps between the portions.
  6. Add the cooled chocolate to the remaining dough, and mix just until combined. Drop the chocolate dough by tablespoonfuls in between the vanilla dough in the pan. The dough will spread as it bakes, but you can gently spread and smooth the doughs if you like.
  7. Bake 30 to 35 minutes, or until the edges are browned and a pick inserted into the center comes out clean.
  8. Cool in the pan for at least 15 minutes before cutting into bars.

  1. I love that these are no scoop – what a relief. They look really gorgeous. Great Post. Sammie x

  2. Just made them and they are a Winner!!! Now added to my repetoire! Very easy and great if you like bars instead of cookies😀

  3. As always, these look yummy. I enjoy your blog so much; not only for the delicious recipes, but I love that you don’t overburden it with too many photos (I don’t need to see what every single ingredient looks like after being adding to the bowl!). Thank you!

  4. I love cookies.can’t wait to eat them.It looks so tasty.

  5. I made these last night…Excellent bar ‘cookie’ with great flavor. Recipe turned out great! I added a tsp of espresso powder to the dough so they have a bit of a mocha flavor, but not too much. I bet they’d be delish with a few tbls of malted milk powder. Although it was 104 degrees outside, why not bake if the AC is on?! 🙂 Thanks, Jennifer!

  6. Great recipe. (Somehow I came across your Instagram which led me to your blog.) Loved the taste. Loved the appearance. Easy to make a half recipe and bake in an 8×8 pan, too. My boyfriend and I ate the whole pan in one sitting while watching a baseball game. (Oink.) Thanks for a great cookie bar recipe. 🙂

  7. I actually HATE baking cookies, but am all in for cookie bars! Love the mix of chocolate and vanilla in these – best of both worlds.

  8. It’s wonderful.Never realize its perfect taste until last night when my friend handed me one of these bars. Out of this world is the words for it. I would love to make it this weekend. Thanks for sharing!

  9. This is pure genius, Jennifer, cookies in bar form. I will definitely be making this recipe when my church’s coffee hour resumes after summer break, and I know they will turn out fantastic. I make many of your recipes, and they never disappoint!

  10. These look great! I wonder, do you know if you can make these in advance? Not sure which stage, maybe mix it put it in the pan and freeze? or freeze after they’re baked?
