Easy 2 Layer Dessert
- COOKIE BASE: Crushed Dad’s oatmeal cookies mixed with melted butter form the base for this recipe. Super easy to make, and so delicious.
- FUDGE LAYER: Using just a few ingredients like chocolate, butter, powdered sugar, walnuts, vanilla and an egg, this gooey and fudgy layer is hard to resist!
Substitutions
- There really is no substitute for the Dad’s cookies in this recipe, but there are some with chocolate chips in them which would work too.
- Semi sweet chocolate chips work well instead of squares. In fact they melt even faster!
- The unsweetened chocolate helps keep the fudge layer from being too sweet. If a sweeter bar is desired, use semi sweet chocolate for the entire 4 ounces.
- Pecans are a great substitute for walnuts, or omit them altogether.
- Use nuts for the topping, or reserve a bit of the cookie base to sprinkle on top.
How to Make Fudge Bars
- Crush the cookies and mix with melted butter.
- Press firmly into an 8×8″ pan and bake for 10 minutes. Cool.
- Melt butter with chocolate in a saucepan.
- Add powdered sugar, vanilla and walnuts. Mix – it will be thick.
- Beat egg and blend into chocolate mixture.
- Cook for 3 minutes, pour over cookie base. Sprinkle with more walnuts.
- Refrigerate until firm, remove from pan and cut into squares.
Recipe Tips!
- Line baking pan with parchment paper or foil to make removal, and clean up, super easy.
- A food processor works best to crush the cookies, but a zippered bag and rolling pin (or mallet) works in a pinch!
- Firmly press the cookie base down before baking to prevent it from crumbling.
- Once chilled and firm, remove the entire slice onto a cutting board and cut into desired sizes.
Storage Ideas!
- Store these cookie bars in a covered container in the refrigerator for about a week, or at room temperature for 3-4 days.
- This recipe is definitely freezer-friendly, so make a double batch and freeze for quick and easy grab and go treats or for last minute guests.
- An ice cream pail makes a great container to store all your freezer treats, plus is a great way to recycle!
