Why Cookie Bars??

Cookie Bars taste just like cookies, but thicker, and often bigger.

Really, you just get more cookie in your mouth per bite, and who doesn’t want that?!

Cookie Bars still have that chewy, soft center, and crisp edges making these a must-make treat.

Whether your cookie of choice is chewy Chocolate Chip cookie bars, Sugar, Oatmeal, or Snickerdoodle, I have a whole variety of Cookie Bar Recipes that will satisfy your cookie craving. Before you check out the list, make sure you see these cookie bar tips.

Making Cookie Bars is a lot like making classic cookies. The dough recipes are very similar, as are the tips and tricks.

Room temperature ingredients. Room temperature butter and eggs incorporate better with the other ingredients, as well as add air to the dough which helps create a fluffy, soft texture. 

Many recipes call for softened butter. Our How to Soften Butter Quickly post can give you tips to do so. 

Muffin method. Combining wet ingredients and dry ingredients in separate bowls, before stirring them together, yields a softer texture. It also prevents overmixing the dough.

Rising agent. Be sure the rising agent, typically baking soda or baking powder, is fresh for the best outcome.

Doneness. For cake-like bars, stick a wooden pick in the center of the pan. If it comes out clean, or with a few moist crumbs, then the cookies are done. Chewy bars will have a dull surface. If you press gently, a slight imprint will remain.

STORE. Like cookies, bars can be stored in an airtight container along with a slice of white bread, which can help keep them softer longer. They can also be stored in the freezer. 

FREEZE the dough. The dough can often be frozen in log form. Simply shape and wrap with plastic, and again with foil. Thaw before pressing into the pan.

Double it. Some recipes are designed for an 8×8 pan, others call for a 9×11 or a 9×13. No matter the pan size, recipes can be doubled for extra treats. 

  • An 8×8 pan recipe can be doubled and baked in a 9×13 pan 
  • Double, press half into the pan to make now, and press half into a pan that you want to freeze for later. (See individual recipes for freezing instructions.)

The flat surface of a Cookie Bar is perfect for adding fun toppings. Some can be added to the top before baking, while other toppings are best when added after baking.

The type of Cookie Bar recipe you make will determine the type of topping you might wish to add. Some ideas include:  

  • Holiday sprinkles
  • Chopped candies or chocolate chips
  • Chopped nuts like walnut or pecans
  • Sliced fruit and berries
  • Frosting or glaze
  • Caramel drizzle 
  • Flaky Sea Salt

Best pan tips

Glass, metal or ceramic. When making Cookie Bars, you get to skip forming cookie dough balls, or even more time consuming – rolling and stamping out cookie shapes. You also get to skip the repetitive process of baking the different pans of cookies.

Cookie Bars ask for baking all of the dough at once, in a single baking pan. You can use different pans to make these cookies, just know that each type does bake a bit differently.

  • Glass and ceramic. Both of these pans retain heat better than metal pans. If you have a recipe that calls for a metal baking pan, but you want to use a glass or ceramic pan, then you usually need to decrease the oven temperature by 25°F. Be aware that both types can shatter with extreme temperature changes. Ceramic pans are often chosen because they come in a bigger variety of patterns and colors. 
  • Metal pans typically heat up more quickly. Dark metals pans will bake more quickly than lighter metal pans. Dull/matte pans also cook foods more quickly than shiny pans. 

Lining the pan. No matter what type of pan you use, I suggest you always line the pan with parchment paper or foil. This makes it significantly easier to cut and remove the baked treat without mutilating the pieces.

  • Leave extra lining so there is enough for you to grab and lift.
  • Spray the pan with cooking spray before adding the parchment paper. This will help keep the paper in place while you press in the dough. 
  • Always allow the treat to cool before removing from the pan.
