Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

For the Ganache Filling:
1/2 cup heavy cream
1 cup semi-sweet chocolate chips

For the Cookie Dough:
1 cup unsalted butter, softened
1 cup brown sugar
1/2 cup granulated sugar
2 large eggs
1 tbsp vanilla extract
2 cups all-purpose flour
3/4 cup unsweetened cocoa powder
1 tsp baking soda
1/2 tsp salt
1 cup mini rainbow candy chips (like Cosmic Chips or rainbow M&Ms)
1/2 cup chocolate chunks or chips

Directions

1. Make the Ganache:
In a small saucepan, heat the heavy cream until it just begins to boil. Pour over the chocolate chips in a heat-safe bowl. Let sit for 1 minute, then stir until completely smooth.
Chill in the refrigerator for 1 hour or freeze in small dollops on parchment paper until firm enough to handle.

2. Make the Cookie Dough:
Cream the softened butter with both sugars until light and fluffy. Add eggs and vanilla extract; beat until combined.
In a separate bowl, sift together flour, cocoa powder, baking soda, and salt. Gradually mix dry ingredients into the wet mixture.
Fold in the rainbow chips and chocolate chunks. Chill the dough for at least 30 minutes to firm up.

3. Assemble & Bake:
Preheat the oven to 350°F (175°C) and line a baking tray with parchment paper.
Scoop out dough portions and flatten slightly in your hand. Place a chilled ganache center in the middle, then wrap the dough around to seal.
Optionally, roll the dough balls in extra rainbow chips.
Place on the baking sheet and bake for 10–12 minutes, until edges are set but centers are soft. Let cookies cool on the tray for 5 minutes before transferring to a rack.

Variations

Flavor Twist: Add a hint of peppermint or orange extract to the ganache for a festive touch.
Nutty Addition: Mix in chopped walnuts or pecans for added texture.

Storage/Reheating

Storage: Store cookies in an airtight container at room temperature for up to 4 days.
Refrigeration: If storing longer, refrigerate for up to 1 week.

Reheating: For a gooey center, microwave cookies for 10–15 seconds before serving.

FAQs

What are cosmic chips, and where can I find them?

Cosmic chips are mini rainbow-colored candy chips often found in baking or candy aisles. If unavailable, mini M&Ms or chopped candy-coated chocolates work as substitutes.

Can I make the ganache filling ahead of time?

Yes, the ganache can be prepared and refrigerated up to 3 days in advance.

How do I keep the cookies from spreading too much?

Chilling the dough before baking helps prevent excessive spreading and ensures a thick, chewy cookie.

Can I use a different type of chocolate for the ganache?

Yes, milk or dark chocolate can be used instead of semi-sweet, depending on your preference.

How do I know when the cookies are done?

Bake until the edges are set and the centers are slightly soft. The residual heat will continue baking them as they cool.

Are these cookies good for shipping?

Yes, once fully cooled, they can be packed securely in layers with parchment paper and shipped.

Can I use store-bought ganache?

Yes, pre-made ganache can be used as a shortcut, though homemade offers the best texture and flavor.

Do I need to chill the ganache and the dough?

Yes. Chilling the ganache makes it easier to stuff, and chilling the dough improves texture and prevents spreading.

Can I add more candy chips on top for presentation?

Definitely. Roll the filled dough balls in extra rainbow chips before baking for a vibrant, decorative touch.

Will the ganache stay molten after cooling?

It remains soft but not fully liquid once cooled. Reheating briefly can restore the molten center.

Conclusion

The Cosmic Stuffed Chocolate Cookie is an extraordinary dessert experience—rich, fudgy, and visually delightful. With its hidden molten ganache center and colorful candy chip crust, it’s a treat that pleases both the eyes and the palate. Whether you’re baking for fun, celebration, or simply craving something unique, this recipe delivers cosmic joy in every bite.
