Hot Chocolate Cookies — These gooey hot chocolate cookies are complete with big gooey marshmallows and chunks of melted dark chocolate. This is the perfect holiday and winter time cookie recipe!
YIELD: 24 COOKIES
1/2 cup unsalted butter
one 12-ounce bag semi-sweet chocolate chips
1 1/4 cups light brown sugar, packed
3 large eggs
2 teaspoons vanilla extract
1/4 cup unsweetened natural cocoa powder
1 1/2 cups all-purpose flour
1 1/2 teaspoons baking powder
1/4 teaspoon salt
about 8 ounces dark chocolate, diced into 1/2-inch pieces (I used a Trader Joe’s Pound Plus Dark Chocolate Bar)
about 12 large marshmallows, cut in half
- To a medium, microwave-safe bowl, add the butter, chocolate chips, and heat on high power to melt for 1 minute. Stop to check and stir.
- Heat in 15-second bursts, stopping to stir after each burst, until chocolate has melted and can be stirred smooth (You’ll likely only need 1 or 2 bursts). Alternatively, melt the chocolate chips and butter in a medium saucepan over low heat, stirring constantly until just melted. Allow melted chocolate mixture to stand for 5 minutes to cool slightly.
- To a separate large bowl, add the brown sugar, eggs, and vanilla. Beat with a handheld electric mixer on medium speed just until blended, about 1 minute.
Add the cooled chocolate mixture and beat on medium speed until just until combined, about 1 minute. Stop and scrape down the sides of the bowl.
- Add the cocoa powder, flour, baking powder, and salt. Beat on low speed just until combined, about 1 minute. Stop and scrape down the sides of the bowl.
- Cover bowl with plastic wrap and refrigerate for 2 hours, or until dough has firmed up significantly. If you accidentally over-chill it and it becomes too firm, allow bowl to rest on counter until you can scoop it.
- Preheat oven to 325F. Line a baking sheet with a Silpat or spray with cooking spray. Using a 2-tablespoon cookie scoop form dough mounds and place them on the baking sheet, spaced at least 2 inches apart (I bake 8 cookies per sheet).
- Flatten slightly and bake for 10 minutes, or until edges and tops have just set, even if slightly undercooked and glossy in the center.
- Remove baking sheet from oven, add 1 piece of dark chocolate to the center of each cookie, pushing down very slightly just so it breaks the surface and sinks down.
- Place one marshmallow half on the top of each piece of chocolate on all the cookies, pushing down very slightly so the marshmallow adheres.
- Return baking sheet to oven and bake for about 5 minutes, or just until marshmallows have puffed; don’t let them brown and don’t overbake. Cookies firm up as they cool.
- Allow cookies to cool on baking sheet for about 10 minutes before serving. I let them cool on the baking sheet and don’t use a rack.
- Cookies will keep airtight at room temperature for up to 1 week.
- Alternatively, unbaked cookie dough can be stored in an airtight container in the refrigerator for up to 5 days, or in the freezer for up to 4 months, so consider baking only as many cookies as desired and save the remaining dough to be baked in the future when desired.
