• Vanilla Extract – Adds warmth and well-rounded flavor; opt for pure vanilla for the best result.
• Quick Oats – Imbue chewiness and texture; mix gently to maintain structure.
For the Fudge Layer

Step‑by‑Step Instructions for Classic Fudge Nut Bars
Step 1: Prepare Baking Pan
Begin by generously spraying a 13 x 9 inch baking pan with non-stick cooking spray. This will prevent your Classic Fudge Nut Bars from sticking to the pan, allowing for easy removal. Set the prepared pan aside while you gather the ingredients.
Step 2: Mix Dry Ingredients
In a mixing bowl, whisk together 1 ½ cups of all-purpose flour, 1 teaspoon of baking soda, and ½ teaspoon of salt until well combined. This step helps to ensure an even distribution of the leavening agent and seasoning, crucial for the right texture in your oatmeal cookie base.
Step 3: Cream Butter and Sugars
In another bowl, cream 1 cup of unsalted butter at room temperature with 1 cup of light brown sugar until the mixture is smooth and fluffy. This should take about 3 minutes on medium speed using an electric mixer. Next, add 2 large eggs and 1 teaspoon of vanilla extract, mixing until everything is beautifully combined.
Step 4: Combine Mixtures
Gradually add the dry mixture to the creamed butter and sugar, stirring gently until just combined. Be cautious not to overmix; this will keep your bars soft. Once incorporated, fold in 1 ½ cups of quick oats, ensuring all ingredients meld together without losing that delightful texture.
Step 5: Layer Base
Press 2/3 of the oatmeal cookie mixture firmly into the prepared baking pan, creating an even base layer. This layer will support the decadent fudge topping, so make sure it’s well packed and smooth across the bottom of the pan for even baking.
Step 6: Make Fudge Layer
In a heavy-bottom saucepan, combine 1 ½ cups of semi-sweet chocolate chips, 1 can of sweetened condensed milk, and 2 tablespoons of unsalted butter over low heat. Stir continuously until the mixture is melted and smooth, about 5 minutes. Once melted, fold in ½ cup of chopped pecans for added crunch, and then pour the fudge over the oatmeal base evenly.
Step 7: Top Fudge with Oatmeal
Crumble the remaining oatmeal cookie mixture over the fudge layer, distributing it evenly. This will create a delightful top layer that complements the gooey fudge beneath. Pat the crumble down slightly to help it adhere to the fudge as it bakes.
Step 8: Bake
Place the pan in a preheated oven at 350°F and bake for 25 to 30 minutes. Keep an eye on the bars as they bake; they should turn a lovely golden brown on top and firm up slightly. A toothpick inserted in the center should come out clean with just a few moist crumbs.
Step 9: Cool and Cut
Once baked, remove the pan from the oven and allow the bars to cool completely in the pan on a wire rack. This cooling period is essential for setting the fudge layer and achieving neat cuts. After about an hour, cut into squares and serve your Classic Fudge Nut Bars, reveling in their rich flavors.

Classic Fudge Nut Bars Recipe FAQs
What type of oats should I use for the oatmeal base?
Use quick oats for the best texture in your Classic Fudge Nut Bars. They provide the necessary chewiness and hold up well when baked. If you don’t have quick oats, traditional rolled oats can work too, though the texture may differ slightly. Just be cautious not to over-process them to avoid a fine powder.
How should I store my fudge nut bars?
Store your Classic Fudge Nut Bars in an airtight container at room temperature for up to 3 days for the best texture and flavor. If you prefer them a bit colder, you can refrigerate them for up to a week, though this may slightly alter the chewiness. Just ensure they’re well-sealed to keep them fresh!
Can I freeze Classic Fudge Nut Bars?
Absolutely! You can freeze these bars for up to 3 months. To do this, wrap individual pieces in plastic wrap, then place them in a freezer-safe bag or container. When you’re ready to enjoy, thaw them in the refrigerator overnight or warm in the microwave for 10-15 seconds to restore that gooey goodness.
What should I do if my fudge layer is too thick?
If you find your fudge layer is too thick and isn’t spreading easily, it may need a quick fix. Gently warm the fudge on low heat in a saucepan, stirring continuously to loosen its consistency. If it remains stubborn, add a splash of milk or cream until it reaches your desired spreadability. Then, pour it over your base and continue as usual!
Are there any dietary considerations I should be aware of?
Yes, when making Classic Fudge Nut Bars, consider nut allergies if serving to family or friends. Pecans can be substituted with walnuts or omitted altogether for a nut-free version. Additionally, ensure that all other ingredients like chocolate chips and sweetened condensed milk fit any dietary restrictions.
