Fudgy Oatmeal Chocolate Chip Cookie Bars
Fudgy Oatmeal Chocolate Chip Cookie Bars offer a dense, chewy texture combining melted butter, brown sugar, rolled oats, and flour with semi-sweet chocolate chips. A rich chocolate layer made by melting chocolate chips with sweetened condensed milk provides moistness and fudgy depth between oat crust layers. The top layer of crumbled oat batter creates a crumbly finish with a balance of textures.

Ingredients
- ½ cup butter 1 stick, melted, unsalted
- 1 egg large
- 1 cup light brown sugar packed
- 1 tablespoon vanilla extract
- 1 ½ cups old-fashioned rolled oats not quick cook or instant
- 1 cup all-purpose flour
- pinch salt optional and to taste
- 1 cup chocolate chips for batter, semi-sweet
- sweetened condensed milk just eyeball it, half of one 14-ounce can
- semi-sweet chocolate chips for sprinkling, about 1/3 cup
Instructions
- Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.
- In a large, microwave-safe bowl melt the butter, about 1 minute on high power.
- Wait momentarily before adding the egg so you don’t scramble it. Add the egg, brown sugar, vanilla, and whisk until smooth.
- Add the oats, flour, and stir until just combined, don’t overmix.
- Turn three-quarters of the batter out into prepared pan, smoothing it with a spatula to form a crust; reserve remainder and set aside.
- In a medium microwave-safe bowl, add 1 cup chocolate chips, pour sweetened condensed milk over the top, and heat on high power until the chips melt and mixture can be stirred smooth, about 45 to 60 seconds.
- Evenly pour chocolate mixture over crust, smoothing the top lightly with a spatula. Work somewhat quickly because mixture begins to set up after a couple minutes.
- Evenly crumble the reserved oatmeal mixture over the chocolate layer. I find it easiest to make heaping 1-tablespoon-sized ‘blobs’, and after all the blobs are in the pan, smoosh and smooth them together with a spatula. The entire surface will not be covered and there will be some gaps.
- Bake for about 25 minutes, or until top is set; it should be very pale in color for soft bars; golden colored means bars will be crunchier.
- Evenly sprinkle bars with about 1/3 cup chocolate chips, or as desired. Chips will soften and melt slightly. Avoid jostling the pan because it will cause chips to melt more rather than stay intact.
- Set pan aside and allow bars to cool in pan for at least 1 hour before slicing and serving.

Notes
- Store bars airtight at room temperature for up to 1 week or freeze for up to 6 months for extended freshness.
