- ¼ cup (50g) granulated sugar: Balances the richness of the brown sugar.
- 1 large egg: Binds the ingredients together.
- 1 tablespoon vanilla: For added depth of flavor.
- 1 tablespoon milk: Helps to achieve the perfect dough consistency.
- ¼ teaspoon salt: Enhances all the flavors.

Step by Step Guide for Peanut Butter Cookie Fudge Bars

Making these bars is a fun and rewarding experience. The aroma of peanut butter and chocolate filling your kitchen is irresistible. Follow these steps carefully to create your own batch of Peanut Butter Cookie Fudge Bars that will have everyone asking for seconds!
- Preheat your oven to 350°F (175°C). Grease a 9×13 inch pan with cooking spray and line it with foil for easy removal later. This ensures your bars come out easily without sticking.
- In a large mixing bowl, combine the softened butter, peanut butter, and both the brown sugar and granulated sugar. Using an electric mixer fitted with a paddle attachment, cream the ingredients together for about 2 to 3 minutes until they are light and fluffy.
- Next, add the egg, vanilla, milk, baking soda, and salt to the mixture. Beat on medium speed until everything is well combined and smooth.
- Gradually add the flour to the mixing bowl and mix on low speed until the dough just comes together. Avoid over-mixing, as this can lead to tough bars.
- Transfer the cookie dough into the prepared pan. Using your hands or a spatula, press the dough evenly into the bottom of the pan, ensuring it’s packed tightly.
- Place the pan in the preheated oven and bake for 18 to 24 minutes. You want the top to turn a lovely golden color; check for doneness by inserting a toothpick into the center—it should come out clean.
- Once baked, remove the pan from the oven and allow it to cool completely. This step is crucial to ensure the fudge layer adheres well.
- While the bars are cooling, prepare the fudge topping. In a saucepan over low heat, combine the chocolate chips and the sweetened condensed milk. Stir frequently until the mixture is melted and smooth.
- Remove the melted fudge mixture from the heat and immediately pour it over the cooled cookie base. Use a spatula to spread it evenly across the surface.
- For an optional finishing touch, sprinkle some colorful sprinkles or chopped nuts on top. Allow the bars to cool completely again, which will set the fudge.
- Once set, lift the bars from the pan using the foil and cut them into squares. Store any leftovers in an airtight container for up to three days.
Things Worth Knowing
- Don’t skip the cooling: Let the cookie base cool completely before adding the fudge. This helps the fudge layer to stay intact.
- Mix slowly: When adding flour, mix on low speed. This prevents the dough from becoming tough and ensures a tender texture.
- Quality ingredients matter: Using high-quality chocolate chips and peanut butter will greatly enhance the flavor of your bars.
- Experiment with toppings: Don’t hesitate to add your favorite toppings to the fudge for a personal touch.
