5. Add the wet to the dry and mix until just combined.

8. Transfer dough to your prepared dish and bake smooth toward the edges. Pop into the oven and bake at 350F for around 35 minutes. The edges will be set and golden but the center will be a bit soft. A skewer should come out clean if inserted in the enter though. People at higher elevations will need a longer bake 🙂

Pro Tips for this recipe

Measure your flour correctly! Adding too much flour to the recipe is the most common mistake. The best, and easiest way to measure flour is by using a scale. If you don't have one then fluff your flour with a spoon, sprinkle it into your measuring cup, and use a knife to level it off.
It is COMPLETELY essential to line your baking dish. If you don't have parchment paper you can use foil instead but don't try to skip this or get away with butter and flouring the pan.
Double this recipe for a 9×13 baking dish.
A sprinkle of flaked sea salt on top just after baking provides a nice bit of contrast.
Love that gooey brownie texture? Try under-baking this a bit and enjoy!

The edges of the cookie will be set; you'll see a rise and they'll be a golden color. The center will not be completely set but a skewer or tooth pick will come out clean in inserted.

What is an example of a bar cookie?

Chocolate chip cookie bars are the most popular but depending on where you are and who you ask brownies can actually be considered cookie bars too! Lemon cookie bars and caramel cookie bars are popular varieties as well.

How long do they last?

Stored in an airtight container these cookie bars will keep for about 3 days at room temp. You can wrap the baked but uncut bars and freeze for up to 3 months.

Don't let them loose all their moisture. As soon as they're cool I would transfer them to an airtight container and store at room temperature.
