Crispy top, with an ooey, gooey, chocolaty fudge center. I hope that this turns out as well for you as it does for me! I place a large piece of aluminum foil or a cookie sheet under my 9x13-inch pan, as it can sometimes get a little bit of overflow. Worth the little bit of mess!

Recipe Instructions
Step 1
Preheat oven to 350 degrees F (175 degrees C).
Step 2
Combine 1 cup butter, brown sugar, white sugar, and eggs in a large bowl; mix until smooth.
Step 3
Mix flour, baking soda, and oats together in another bowl. Add to the butter mixture slowly; mix using an electric mixer until combined.
Step 4
Spread 3/4 the oat mixture into an ungreased 9x13-inch baking pan using a spatula. Press lightly into the bottom of the pan to make the surface even.
Step 5
Combine chocolate chips, sweetened condensed milk, 1/3 cup butter, and vanilla extract in a saucepan over medium-low heat. Stir until melted and smooth, about 2 minutes. Pour fudge over the oatmeal base and spread evenly.
Step 6
Drop tablespoons of remaining oatmeal mixture over the fudge. Press oatmeal down lightly to flatten and swirl into the fudge.
Step 7
Bake in the preheated oven until the top is lightly browned, 25 to 30 minutes; the chocolate should still be moist. Cool completely on a wire rack, about 45 minutes. Cut into squares.
