These look like simple chocolate-frosted cookies. But take a bite and you’ll uncover the reason they’re called surprise cookies… there’s a marshmallow hidden inside! These cookies will make you feel like a kid again.
(This recipe for Chocolate Surprise Cookies was originally posted in January 2008, but was updated with new photos in 2018).
I don’t make cookies often enough (probably because I’m obsessed with making cupcakes), but I wanted to switch things up tonight for dinner with a friend. Um, have you ever stopped to think about how many different types of cookies are out there? SO many. But after much looking at pretty much every cookie recipe in the world (no lie), I found a recipe that involves chocolate and marshmallows. That’s all I need to know.
These chocolate surprise cookies come from a Martha Stewart Kids recipe. But what differentiates a kid’s cookie from an adult’s cookie, I ask you? A simple marshmallow? Well, if that’s the case, I think I’d prefer to be a kid forever, thank you very much. I’m definitely not willing to give up marshmallows and I’m an adult that is going all in for the surprise aspect of these chocolate surprise cookies.
CHOCOLATE SURPRISE COOKIES RECIPE
The batter for the cookies is simple to make with flour, cocoa powder, eggs, milk, vanilla, butter, sugar, and baking soda. The cookies are baked for 9 minutes, before you take them out of the oven and push half a marshmallow into the center of each. Then back in the oven for another minute. How easy is that?
Whip up a quick frosting consisting of cocoa powder, confectioner sugar, butter, vanilla, and milk.
And put a tablespoon of frosting in the center of the cookie, covering the marshmallow (hence the surprise part of the cookie).
So sneaky…they seem like simple chocolate cookies! You would never suspect anything suspicious going on, right??

- 1/2 tsp baking soda
- 1/2 tsp salt
- 1/2 cup (1 stick) unsalted butter, room temperature
- 1 cup granulated sugar
- 1 large egg
- 1 tsp vanilla extract
- Chocolate frosting (recipe below)
- 12 large marshmallows, cut in half horizontally
- Sprinkles, optional for topping
- 2 cups confectioners' sugar
- 1/4 cup cocoa powder
- 4 Tbsp (1/2 stick) unsalted butter, melted
- 1/4 tsp vanilla extract
- 1/4 cup milk
- Pre-heat oven to 375 degrees.
- n a medium bowl, whisk flour, cocoa powder, baking soda, and salt together.
- In the bowl of a stand mixer or in a large bow with a hand mixer or whisk, cream butter and sugar together until light and fluffy, about 3 minutes. Add egg, milk, and vanilla, and beat until well combined.
- Slowly add flour mixture and mix until just combined, taking care not to over-mix.
- Drop about a tablespoon of dough onto an ungreased cookie sheet, about 2 inches apart. Bake until cookies for 9 minutes before removing from the oven.
- Place a marshmallow, cut-side down, in the center of each cookie, pressing down slightly. Put the cookie sheet back into the oven and continue baking for just one more minute, until marshmallows begin to melt. Remove from oven and transfer cookies to a wire rack to cool completely before frosting.
- Starting in the center of the marshmallow and continuing outward, spread about 1 tablespoon of frosting over the marshmallow, until it's completely covered. Top with sprinkles if desired and let frosting harden before serving.
- In a medium bowl, whisk together confectioners' sugar and cocoa powder. Add melted butter and vanilla, while continuing to whisk until combined. Mix in milk and whisk until smooth.
