Marshmallow-Surprise Hot Cocoa Cookies
Decadent chocolate cookies with a gooey marshmallow center and rich cocoa flavor. Perfect for cozy winter nights and holiday treats.

Creating the Perfect Surprise Center
The key to achieving the perfect marshmallow surprise is ensuring the cookie dough is chilled and firm enough to properly encase each marshmallow. The mini marshmallows work best because they melt to the ideal gooey consistency without making the cookies too sweet or overly sticky.
When wrapping the dough around each marshmallow, make sure to seal the edges completely to prevent the marshmallow from leaking out during baking. The chocolate cookie dough acts as a protective shell that creates the perfect surprise element when bitten into.
💡 Professional Tip
Freeze the shaped cookies for 15 minutes before baking to help them hold their shape and prevent spreading. This ensures the marshmallow stays centered and the cookies maintain their thick, chewy texture.
Frequently Asked Questions
Mini marshmallows work best for proper proportions. If using regular marshmallows, cut them into quarters to avoid overly large cookies or bursting during baking.
Ensure the dough completely covers each marshmallow and pinch the seams tightly. Chilling the shaped cookies before baking also helps maintain the seal.
Yes! You can shape the cookies and freeze them for up to 1 month. Bake directly from frozen, adding 1-2 extra minutes to the baking time.

Absolutely! Try adding crushed graham crackers for s'mores flavor, or peppermint extract and crushed candy canes for a winter twist.
The edges should be set but the centers will look slightly underbaked. They'll continue cooking on the hot pan, so don't overbake or the marshmallows will become too firm.
Yes, Dutch-process cocoa will give a richer flavor, while natural cocoa provides more acidity. Both work well, but adjust the baking soda slightly if using Dutch-process.
They're perfect on their own, but try serving with a glass of cold milk, vanilla ice cream, or even alongside a mug of actual hot cocoa for the ultimate cozy experience.
Recipe Troubleshooting Guide
Marshmallow Leaking
Problem: Marshmallows burst out of cookies during baking
Solution: Ensure complete sealing of dough around marshmallow, chill shaped cookies before baking, and don't overbake.
Cookies Too Flat
Problem: Cookies spread too much and lose their shape
Solution: Chill dough longer, don't overmix, and make sure oven is fully preheated. Use parchment paper, not greased pans.
Hard Marshmallow Centers
Problem: Marshmallows become hard instead of gooey
Prevention: Don't overbake - cookies should look slightly underdone in centers. The marshmallows will firm up as they cool.
Dry Cookie Texture
Problem: Cookies turn out dry instead of soft and chewy
Recovery: Don't overbake, ensure proper measuring of ingredients, and store with a slice of bread to maintain moisture.
Uneven Baking
Problem: Some cookies bake faster than others
Prevention: Use light-colored baking sheets, rotate pans halfway through baking, and ensure cookies are similar sizes.
Flavor Balance Issues
Too Sweet: Add a pinch of espresso powder or increase cocoa slightly
Too Salty: Reduce salt in next batch, balance with extra vanilla
Bland: Increase hot cocoa mix, add more vanilla, or include a touch of cinnamon

Choosing the Right Ingredients
The foundation of these cookies lies in using high-quality cocoa powder and hot cocoa mix. The combination creates a deep, rich chocolate flavor that truly captures the essence of hot cocoa. Using both brown and granulated sugar provides the perfect chewy texture while enhancing the chocolate notes.
Mini marshmallows are essential for the right proportion and melting characteristics. They provide just enough gooey surprise without overwhelming the cookie or making it too sweet. The addition of mini chocolate chips adds extra bursts of chocolate throughout each bite.
Essential Ingredient Notes
- Cocoa Powder: Use unsweetened cocoa powder for the best chocolate flavor. Dutch-process cocoa will give a more mellow, rich taste while natural cocoa provides brighter notes.
- Hot Cocoa Mix: Choose a quality hot cocoa mix without marshmallows already included. This adds the authentic hot cocoa flavor and helps with the cookie's texture.
- Marshmallows: Mini marshmallows are crucial - they're the perfect size for individual cookies and melt to the ideal gooey consistency without being overwhelming.

Mastering the Baking Technique
The secret to perfect marshmallow-surprise cookies is timing and temperature control. The cookies need to bake just long enough for the exterior to set while keeping the marshmallow centers perfectly gooey. Underbaking slightly is better than overbaking, as the cookies continue to cook on the hot pan.
Proper shaping is crucial for success. Each cookie should have enough dough to completely encase the marshmallow, with all seams tightly pinched. Chilling the shaped cookies helps them maintain their form and prevents excessive spreading during baking.
The Perfect Seal
Flatten the dough, place the marshmallow in the center, then gather the edges and pinch tightly. Roll gently between palms to smooth any seams before placing on baking sheet.
