How to Make Fudge Stuffed Chocolate Chip Cookie Bars

Preheat your oven to 350°F (175°C). This ensures a perfectly baked cookie bar with a golden-brown exterior.
Cream the softened unsalted butter together with both brown and granulated sugars in a mixing bowl until light and fluffy. This step typically takes about 2-3 minutes for the ideal texture to form.
Add the eggs, vanilla extract, and salt to your creamy mixture, mixing until everything is well combined. This mixture should be smooth and deliciously aromatic.
Gradually mix in the baking soda and all-purpose flour until just combined. Be careful not to overmix, as this could make your bars tough. Gently stir in the semi-sweet chocolate chips.
Press about 2/3 of the cookie dough into a greased and foil-lined 9×13″ pan, creating an even layer at the bottom. It should feel slightly sticky, but that’s just perfect!
For the fudge: Combine the sweetened condensed milk and chocolate chips in a microwave-safe bowl. Heat in 30-second intervals, stirring in between until the mixture is melted and smooth.
Pour the fudge mixture over the cookie dough layer, spreading it evenly. This is where the magic happens—the fudge will ooze deliciousness!
Flatten the remaining cookie dough and layer it gently on top of the fudge layer. The fudge should be covered completely to keep the gooey goodness inside!
Bake for 22-25 minutes, or until the edges are golden and begin pulling away from the pan. The center will look slightly soft, which is just right.
Cool the bars completely in the pan, then chill in the refrigerator for at least 2 hours before cutting into squares. Chilling allows for clean cuts and perfect presentation.

Optional: Drizzle melted chocolate on top before serving for an extra touch!

Fudge Stuffed Chocolate Chip Cookie Bars Recipe FAQs

How do I select the right ingredients for the cookies?
Absolutely! For the best results, choose unsalted butter that is soft but not overly melted to ensure proper creaming with the sugars. When selecting chocolate chips, feel free to go for high-quality semi-sweet or dark chocolate chips, as they’ll enhance the flavor of your fudge. Always check the dates on your baking powder and flour to ensure freshness—older ingredients can result in less-than-perfect bars.

How should I store leftover cookie bars?
To truly savor each bite, store these Fudge Stuffed Chocolate Chip Cookie Bars in an airtight container at room temperature for up to 3 days. If you’d like to enjoy them longer, refrigerate the bars, which can keep them fresh for about a week. Make sure the container is well-sealed to avoid any unwanted odors from the fridge.

Can I freeze these cookie bars? How do I do it?
Of course! Freezing is an excellent way to preserve these treats. Wrap each bar tightly in plastic wrap and then store them in an airtight container or a resealable freezer bag. These can be frozen for up to 3 months. When you’re ready to indulge, simply remove the bars from the freezer and allow them to thaw at room temperature. For that freshly baked vibe, pop them in the microwave for a few seconds!

What do I do if my cookie bars turn out too soft?
Very common! If your bars are soft after baking, don’t worry. Let them cool completely in the pan, and if they still feel too gooey, chill them in the refrigerator for at least 2 hours. This cooling period helps firm up the texture, making them easier to cut. Also, double-check your baking time; every oven is different, and sometimes an extra couple of minutes can make a difference.

Are there any dietary considerations I should keep in mind?
Absolutely! If you’re making these bars for someone with dietary restrictions, consider using gluten-free flour and checking for allergy-friendly chocolate options. As for pets, keep these delicious bars away from furry friends—ingredients like chocolate and sugar are not safe for them. Always be mindful of the ingredients, especially if someone has nut or dairy allergies in your group.
