Ingredients

For the Oat Cookie Base:

1. Butter — adds richness and moisture (use softened butter for easiest mixing).
2. Brown sugar — sweetens and contributes chewiness and a light caramel note.
3. Eggs — bind the dough and provide structure.
4. Vanilla — enhances overall flavor with a warm aroma.
5. All-purpose flour — provides structure to the cookie base.
6. Quick oats — give texture and a hearty chew.
7. Salt — balances sweetness and brightens flavors.
8. Baking soda — helps the bars rise and set properly.

For the Fudge Mixture:

1. Butter — enriches the fudge layer.
2. Chocolate chips — form the chocolate base; semi-sweet, dark, or milk work well.
3. Sweetened condensed milk — adds creaminess and helps set the fudge.
4. Salt — balances sweetness.
5. Vanilla extract — deepens the chocolate flavor.
6. Chopped nuts (optional) — add crunch and a nutty contrast.

Each ingredient contributes to a layered bar that is both hearty and indulgent.

How to Make Fudge-Stuffed Cookie Bars

Oatmeal Mixture:

1. Cream softened butter with brown sugar, then add eggs and vanilla and mix until smooth.
2. Whisk together flour, oats, salt, and baking soda in a separate bowl. Combine with the wet mixture until evenly mixed.
3. Grease a 10×15″ jelly roll pan. Press about two-thirds of the oatmeal mixture evenly into the bottom of the pan (the dough will be thick).

Fudge Mixture:

1. Melt butter, chocolate chips, and sweetened condensed milk together in a double boiler, stirring until smooth. Alternatively, microwave in 30-second intervals, stirring between each until melted.
2. Stir in salt, vanilla, and nuts if using.

Assembly and Baking:

1. Spread the warm fudge over the oatmeal base as evenly as possible.
2. Crumble the remaining oatmeal dough over the fudge layer; press lightly in places but it’s fine if the fudge peeks through.
3. Bake at 350°F (180°C) for about 20 minutes, until edges are lightly browned and bars appear set.

Allow to cool, then cut into squares and enjoy.
