Momofuku’s Cornflake Cookie Ingredients
For the Dough
- Cornflakes – The star ingredient that provides that signature crunch; feel free to substitute with any crispy breakfast cereal.
- All-purpose flour – This gives structure to your cookies; you can use whole wheat flour for a nuttier flavor.
- Baking soda – A leavening agent that ensures your cookies rise nicely; omitting it will result in denser cookies.
- Butter – Adds richness and moisture; substitute with coconut oil for a dairy-free twist.
- Brown sugar – Infuses a caramel-like flavor and moisture; white sugar can be used but will slightly alter the texture.
- Granulated sugar – Provides sweetness and contributes to a crisp cookie; you can reduce it for a less sweet treat.
- Eggs – Important for binding the ingredients together; swap for unsweetened applesauce (1/4 cup per egg) for a vegan option.
- Vanilla extract – Enhances the overall flavor of the cookies; can be omitted for a purer taste.
- Chocolate chips – The main flavor component; use milk, semi-sweet, or dark chocolate, or try butterscotch for a twist.
- Mini marshmallows – Boost the chewy texture and sweetness; larger marshmallows can be used if cut smaller.
For the Mix-Ins
- Optional nuts – Add chopped pecans or walnuts for an extra crunch; any kind works well!
- Spices – Introduce cinnamon or nutmeg if you want to explore different flavor profiles.
Note: These delightful cookies are sure to impress and satisfy with their unique blend of textures and flavors, proving that Momofuku’s Cornflake Chocolate Chip Marshmallow Cookies can be an indulgent treat without the fuss!
How to Make Momofuku’s Cornflake Chocolate Chip Marshmallow Cookies
- Preheat the oven to 375°F (190°C). This helps the cookies bake evenly and achieve that perfect golden color.
- Cream together the butter, brown sugar, and granulated sugar in a large bowl until fluffy. This usually takes about 2-3 minutes—trust me, you want this step to be airy!
- Add eggs and vanilla to the mixture, beating until everything is beautifully combined. The batter should look smooth and inviting after this step.
- Whisk together the flour and baking soda in a separate bowl. This ensures all dry ingredients are evenly distributed before joining them with the wet ingredients.
- Mix the dry ingredients into the wet mixture gradually. Stir until just combined; be careful not to overmix, as we want those cookies nice and soft.
- Fold in the chocolate chips, mini marshmallows, and cornflakes with a spatula or spoon until everything is evenly distributed. The crunch from the cornflakes is what makes these cookies so special!
- Scoop tablespoon-sized portions of dough onto a baking tray lined with parchment paper. Leave enough space between each dollop to allow for spreading.
- Bake for 10-12 minutes, or until the edges are lightly golden. Keep an eye on them to achieve that perfect chewy center!
- Cool the cookies on the pan for a few minutes before transferring them to an airtight container. This will help them maintain their shape and texture.
Optional: Drizzle with melted chocolate for an extra decadent touch!

Momofuku’s Cornflake Chocolate Chip Marshmallow Cookies Recipe FAQs
How do I choose the right cornflakes for my cookies?
Absolutely! Look for cornflakes that are fresh, without any dark spots or signs of staleness. The crunchier, the better! You can also substitute cornflakes with other crispy breakfast cereals such as rice puffs or bran flakes if you prefer a different texture.
How do I store Momofuku’s Cornflake Chocolate Chip Marshmallow Cookies?
To keep your cookies fresh, store them in an airtight container at room temperature for up to 5 days. This method will help maintain that delightful chewy center and the satisfying crunch of the edges. If you want to extend their life, you can refrigerate them for up to a week, but ensure they are sealed well to prevent them from becoming dry.
Can I freeze Momofuku’s Cornflake Chocolate Chip Marshmallow Cookies?
Definitely! To freeze, place your cookies in a single layer on a baking sheet until they are solid. This takes about 1-2 hours. Once frozen, transfer them to a freezer-safe container, layering parchment paper between to prevent sticking. They can be stored this way for up to a month. When you’re ready to enjoy, just reheat them in the oven at 350°F (175°C) for about 5-7 minutes to restore their fresh-baked taste.
What should I do if my cookies are too hard?
Very! If your cookies turn out too hard, it might be due to overbaking or overmixing the dough. To prevent this, always check for doneness by looking for lightly golden edges. If you’re facing tough cookies, consider adjusting your baking temperature or reducing the mixing time next time. And remember, cooling them on the pan also helps maintain their softness!
Are there any allergy considerations with these cookies?
Of course! If you’re making these cookies for someone with allergies, be cautious with the ingredients. They contain gluten (from the flour), dairy (from the butter), and eggs. To make them allergy-friendly, you can use gluten-free flour, dairy-free butter substitutes, and replace the eggs with unsweetened applesauce (1/4 cup per egg). Always double-check ingredients to ensure they meet dietary restrictions!
How can I customize the flavors in Momofuku’s cookies?
The more the merrier! You can get creative with add-ins—try adding nuts like chopped pecans or walnuts for added crunch, or sprinkle in some spices such as cinnamon or nutmeg for a delightful twist.
