Oatmeal Chocolate Chip Coconut Cookie Bars

• servings: 24 servings
• active time: 20 minutes
• total time: 40 minutes

Ingredients

3/4 cup (75 g) old-fashioned rolled oats

1 2/3 cups (237 g) all-purpose flour

1 teaspoon baking soda

1/2 teaspoon salt

3/4 cup (170 g) salted butter, melted (see note)

1 1/3 cups (283 g) packed light or dark brown sugar (or a combo)

1 large egg

1 large egg yolk

1 teaspoon vanilla

3/4 cup (64 g) sweetened or unsweetened coconut flakes

1 1/2 to 2 cups (255-340g) semisweet or bittersweet chocolate chips

Directions

Preheat oven to 350 degrees F. Line a metal 9X13-inch pan with parchment and lightly grease with cooking spray (see note for other types of pans).

Add the oats, flour, baking soda, and salt to a blender and pulse until coarsely blended. The texture of the oats should be finer than quick oats but not as fine as flour. Set aside.

To a large bowl, add the melted butter, brown sugar, egg, egg yolk, and vanilla and stir with a wooden spoon or rubber spatula until the ingredients are well combined and the batter lightens a bit in color.

Add the dry ingredients, coconut, and chocolate chips and mix.

Press the batter evenly into the prepared pan. Bake for 20 minutes until set around the edges but still slightly soft in the center. It's ok if you need to add additional baking time, just keep an eye on the bars - they are better just slightly under baked.

Notes

2/28/26 made as written without adjustments other than adding a bit of egg white with egg yolk. Good.

1/10/26 Made gf using 237 g Kats gf flour blend (119 g tapioca flour; 59 g millet flour; 59 g buckwheat flour), 1/2 teaspoon xanthan gum, reduce butter to 120 g, add 1 Tablespoon milk, let sit in pan 10-15 minutes in the pan before baking. I used 183 g light brown sugar and 100 g dark brown sugar. Preheat oven to 365 but reduce to 350 when putting pan in and bake for 20 minutes. It was gooey the first day but very dry thereafter. Either reduce flour, increase butter or add more liquid if trying gf again.

Probably need to adjust slightly for high altitude if making with regular flour by adding 1-2 tablespoons, adding 1 tablespoon liquid.

Pan: I prefer to use a light colored metal baking pan for bar cookie recipes like this. Glass pans, ceramic pans and dark coated pans bake differently. If using one of those pans, try decreasing the oven temperature by 25 degrees.

Butter: I use salted butter. To take these bars up a notch, try browning the butter. Let it cool to just slightly warm room temp before using in the recipe.
