- 9×13-inch baking pan – Ideal for baking and serving your bars.

Mississippi Mud Pie Bars: From Prep to Plate

Creating these Mississippi Mud Pie Bars is a fun and rewarding process! Follow these steps for a delicious outcome.
Step 1: Prepare the Cookie Dough Base
Start by preheating your oven to 350°F (175°C). Press the softened chocolate chip cookie dough evenly into the bottom of a greased 9×13-inch baking pan. Bake for 10-12 minutes or until the edges are lightly golden. Allow the crust to cool completely while you prepare the next layers.
Step 2: Mix the Chocolate Pudding
In a medium bowl, whisk together the instant chocolate pudding mix and cow’s milk. Make sure to use cow’s milk, as alternative milks will not allow the pudding to set properly. Whisk until smooth and set aside for about 5 minutes to thicken.
Step 3: Prepare the Cream Cheese Layer
In another bowl, use an electric mixer to beat the softened cream cheese until smooth. Add the marshmallow creme or fluff, mixing until well combined. Fold in the Cool Whip gently until the mixture is light and fluffy.
Step 4: Assemble the Bars
Once the cookie crust has cooled, spread the chocolate pudding layer evenly over the crust. Next, spoon the cream cheese and marshmallow layer on top of the pudding, smoothing it out with a spatula. Sprinkle half of the chopped Oreo cookies over the cream cheese layer.
Step 5: Add the Final Touches
Drizzle the warmed hot fudge over the top, and then sprinkle the remaining chopped Oreo cookies. Cover the baking pan with plastic wrap and refrigerate for at least 4 hours, or overnight, to allow the bars to set properly.
Step 6: Serve and Enjoy!
Once set, remove the bars from the refrigerator and lift them out of the pan using the parchment paper. Cut into squares and serve chilled. These Mississippi Mud Pie Bars are best enjoyed cold, so keep them in the fridge until you’re ready to dig in!
Warm & Cool Weather Spins

These Mississippi Mud Pie Bars are incredibly versatile. Here are a few spins you can try based on the season or occasion:
- Summer: Serve with fresh berries on the side for a refreshing contrast.
- Fall: Add a sprinkle of cinnamon or nutmeg to the cream cheese layer for a warm spice flavor.
- Winter: Top with crushed peppermint candy canes for a festive touch.
- Spring: Incorporate a layer of lemon zest into the cream cheese mixture for a bright twist.
Mistakes Even Pros Make
Even experienced bakers can run into a few common pitfalls when making Mississippi Mud Pie Bars. Here are some tips to avoid those mistakes:
- Not allowing the cookie dough to soften enough can lead to uneven baking. Make sure it’s at room temperature.
- Using non-dairy milk for the pudding can prevent it from setting properly. Stick to cow’s milk for the best results.
- Rushing the chilling time can cause the layers to not set well, resulting in a messy slice. Patience is key!
- Overmixing the cream cheese and marshmallow can lead to a dense texture instead of a light and fluffy layer.
How to Store & Reheat
To keep your Mississippi Mud Pie Bars fresh and delicious:
- Store any leftovers in an airtight container in the refrigerator for up to 5 days.
- These bars are best enjoyed cold, so there’s no need to reheat them. If you prefer them slightly warm, allow them to sit out for a few minutes before serving.
- Avoid freezing, as the texture may change once thawed.
Helpful Q&A
Can I use a different type of cookie dough for the base?
Absolutely! While chocolate chip cookie dough is traditional, feel free to experiment with other flavors like peanut butter or sugar cookie dough for a unique twist.
How can I make these bars gluten-free?
To make gluten-free Mississippi Mud Pie Bars, simply use a gluten-free chocolate chip cookie dough and ensure all other ingredients are gluten-free.
What can I substitute for Cool Whip?
If you prefer not to use Cool Whip, you can whip heavy cream with sugar and vanilla extract until soft peaks form, then fold it into the cream cheese and marshmallow mixture for a homemade version.
Can I add nuts to the bars?
Definitely! Chopped nuts such as walnuts or pecans can be added to the cookie dough base or sprinkled on top for added crunch and flavor.
