Science Behind the Sweet: Nutritional Breakdown
Let’s demystify what goes into this giant gooey cookie and how each ingredient supports the flavor and your body:
-
Butter: Offers richness and essential fat for flavor, moisture, and browning. It’s a source of vitamin A.
-
Egg: Provides structure and acts as a binding agent. Also adds protein and lecithin for emulsification.
-
Marshmallow fluff: A sweet aerated treat made from egg whites and sugar. While high in sugar, it adds volume without extra fat.
-
Chips Ahoy cookies: Pre-made chocolate chip cookies introduce a unique crunch and extra chocolate flavor, while also shortening prep time.
-
Chocolate chips: Rich in flavonoids and theobromine, especially if dark or semi-sweet.
-
Graham crackers: The foundation of classic s’mores; they add a hint of cinnamon and crunch.
-
Flour + Baking soda: Core to the cookie dough base. Baking soda promotes rise and chewiness.
Step-by-Step Cooking Instructions
Here’s how to build your Chips Ahoy S’mores Cookie with Marshmallow Fluff like a pro:
Step 1: Prep the Base
-
Preheat your oven to 175°C (350°F).
-
Grease or line a 9-inch round baking pan with parchment paper.
Step 2: Cream Butter & Sugar
-
In a bowl, cream 113g butter with brown and white sugar using a hand mixer for 3-4 minutes.
-
Add 1 egg and 1 tsp vanilla extract; beat until light and fluffy.
🔥 Pro Tip: Whip the butter until pale for a softer, more tender cookie texture.
Step 3: Add Dry Ingredients
-
In a separate bowl, whisk together flour, baking soda, and salt.
-
Gradually fold dry mix into the wet mix.
Step 4: Add Crunch & Sweetness
-
Gently fold in crushed Chips Ahoy cookies, chocolate chips, and graham cracker crumbs.
🍪 Pro Tip: Leave some cookie chunks whole for extra texture and visual appeal.
Step 5: Assemble the Cookie Layer
-
Spread half the dough into the baking pan.
-
Spread an even layer of marshmallow fluff on top.
-
If desired, add a layer of mini marshmallows for extra gooeyness.
-
Top with remaining dough—don’t worry if it doesn’t fully cover the fluff; gaps are okay!
Step 6: Bake
-
Bake for 22–25 minutes until golden brown and puffed.
-
Let cool for 15–20 minutes before slicing—it firms up as it cools.
✨ For toasted top: Broil for 1-2 minutes after baking for that golden, toasty marshmallow crust.
