- 2 cups all-purpose flour
- 2 teaspoons cornstarch

- 1/2 teaspoon salt, or to taste
- 1 1/2 cups mini semi-sweet chocolate chips
- 1 cup mini marshmallows
What You’ll Need (Gear)
Before you get started, make sure you have the following gear on hand:
- Mixing bowls: For combining your ingredients.
- Measuring cups and spoons: Accurate measurements are key!
- Spatula: To mix and spread your cookie dough.
- Baking dish: A 9-inch pie dish works perfectly for this recipe.

Gooey Chocolate Chip and Marshmallow Cookie Pie: From Prep to Plate

Step 1: Cream the Butters and Sugars
In a mixing bowl, beat together the softened unsalted butter, light brown sugar, and granulated sugar until the mixture is light and fluffy. This should take about 3-5 minutes. The creaming process is essential as it incorporates air into the mixture, resulting in a lighter texture.
Step 2: Add the Egg and Vanilla
Next, add the large egg and vanilla extract to the butter-sugar mixture. Beat until fully combined and smooth.
Step 3: Combine the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, cornstarch, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, stirring until just combined. Be careful not to overmix, as this can lead to a tougher texture.
Step 4: Fold in the Chocolate Chips and Marshmallows
Gently fold in the mini semi-sweet chocolate chips and mini marshmallows until evenly distributed throughout the cookie dough. This is where the magic happens—those little pockets of chocolate and gooey marshmallow will create a delightful surprise in every bite.
Step 5: Prepare the Baking Dish
Grease your 9-inch pie dish lightly with butter or non-stick spray. This will ensure that your Gooey Chocolate Chip and Marshmallow Cookie Pie comes out easily once baked.
Step 6: Spread the Dough
Pour the cookie dough into the prepared pie dish and spread it out evenly with a spatula. Don’t worry if it looks a bit thick; it will spread and puff up as it bakes.
Step 7: Bake
Place the pie dish in the preheated oven and bake for about 25-30 minutes, or until the edges are golden brown and the center is set but still slightly gooey. Remember, the pie will continue to cook a little after you take it out of the oven, so don’t overbake!
Step 8: Cool and Serve
Allow your Gooey Chocolate Chip and Marshmallow Cookie Pie to cool in the dish for about 10-15 minutes before slicing. Serve warm and enjoy the delightful melty chocolate and marshmallow goodness!
Easy Ingredient Swaps

If you’re missing some ingredients or want to switch things up, here are a few easy swaps you can make:
- Butter: Use coconut oil for a dairy-free version.
- Granulated sugar: Coconut sugar can be used for a more natural sweetener.
- Mini marshmallows: Replace with vegan marshmallows for a plant-based option.
- Chocolate chips: Dark chocolate chips or carob chips can be a great alternative.
Frequent Missteps to Avoid
Baking can be tricky, so here are some common pitfalls to watch out for:
- Don’t overmix the dough after adding the flour, as this can lead to a dense cookie.
- Make sure your oven is properly preheated for even baking.
- Check the cookie pie at the lower end of the baking time to avoid overbaking.
- Allow the pie to cool slightly before slicing to ensure the gooey center holds together.
How to Store & Reheat
To keep your Gooey Chocolate Chip and Marshmallow Cookie Pie fresh, follow these tips:
Store any leftovers in an airtight container at room temperature for up to 3 days. If you want to keep it longer, you can refrigerate it for up to a week. To reheat, simply warm individual slices in the microwave for about 10-15 seconds, or until warmed through. This will help revive that gooey texture!
