Brown Butter Oatmeal Cookie Bars
These brown butter oatmeal cookie bars have a sweet and chewy cookie base loaded with oats and chocolate chips. They're a great quick and easy recipe to whip up when you don't want to bother scooping your dough.
Ingredients
- 1 cup (227 g) salted butter browned
- ¾ cups (165 g) brown sugar
- ⅓ cup (66.67 g) granulated sugar
- 1 large egg + 1 yolk
- 2 teaspoons vanilla extract
- 1½ cups (210 g) all-purpose flour
- 1 teaspoon cornstarch
- 1 teaspoon (1 teaspoon) baking soda
- ½ teaspoon (0.5 teaspoon) salt
- ½ teaspoon (0.5 teaspoon) cinnamon
- 1 cup (104 g) old fashioned oats
- 1 cup (180 g) chocolate chips + more for topping
- flaked salt for topping
Instructions
- Start by browning the butter. You'll take one cup of butter and melt in a medium saucepan, and then continue to cook past the point of boiling. You will do this over medium heat, past the point of the butter foaming, until it turns a nice golden brown, and has a nutty smell. Make sure you are stirring and watching it, because it will turn from perfectly brown to burnt fairly quickly. Once finished browning, pour into a bowl and allow to cool.
- Preheat oven to 325 F. Spray and or line a 9x13 pan with cooking spray and parchment paper.
- Whisk together the cooled butter and both sugars in a large mixing bowl. Add egg, egg yolk and vanilla and whisk again.
- Mix the flour, salt, soda, cornstarch, cinnamon and oats into the dough.
- Fold in the chocolate chips.
- Spread the batter into your 9x13 pan and add some extra chocolate chips to the top.
- Bake for 20-24 minutes, or until golden brown along the edges and no jiggling in the middle. Sprinkle with flaked salt and allow to cool before serving.
Notes
Baking in a metal/aluminum pan is always suggested over glass. The pan will heat more evenly and the bars will cook better. If baking in glass it will take a bit longer for the middle to bake and set up properly.
If you are in a rush you can melt the butter instead of browning it.
You can also bake these in a 9x9 baking dish for a thicker bar. You will need to bake them for 5-10 minutes longer.
I have given both cups and grams as measurements. Grams will be more precise, especially when measuring flour. If you don’t have a kitchen scale, no problem! Just lightly spoon flour into your measuring cup to insure its not packed in there. Light and fluffy is the key.
