Total time: 1 h 15 min
Cuisine: American
Ingredients: ½ cup unsalted butter (softened); ½ cup light brown sugar; ¼ cup granulated sugar; 1 large egg; 1 teaspoon vanilla extract; 2 tablespoons light corn syrup; ¼ teaspoon baking soda; ¼ teaspoon salt; ½ cup dark cocoa powder (Hershey’s Special Dark recommended); 1¼ cup all-purpose flour; ¾ cup semi-sweet chocolate chips; ¼ cup heavy cream; Rainbow chip sprinkles

Ingredients

½ cup unsalted butter, softened

½ cup light brown sugar

¼ cup granulated sugar

1 large egg

1 teaspoon vanilla extract

2 tablespoons light corn syrup

¼ teaspoon baking soda

¼ teaspoon salt

½ cup dark cocoa powder (such as Hershey’s Special Dark)

1 ¼ cup all-purpose flour

¾ cup semi-sweet chocolate chips

¼ cup heavy cream

Rainbow chip sprinkles

Instructions

Step 1: Preheat your oven to 350°F (175°C).

Step 2: In a large bowl, use an electric mixer on medium-high speed to cream the softened butter, light brown sugar, and granulated sugar together for about 2 minutes until the mixture is light and fluffy.

Step 3: Add the egg, vanilla extract, and light corn syrup. Mix on low speed until fully combined, scraping down the sides of the bowl to incorporate everything evenly.

Step 4: Stir in the baking soda and salt, mixing for another 5 to 10 seconds until combined.

Step 5: Add the dark cocoa powder and all-purpose flour. Mix on medium speed until you achieve a smooth dough.

Step 6: Scoop the dough into ¼ cup portions and roll each into a ball. Gently flatten each ball into a disc about ½ inch thick to help the cookies spread evenly while baking.

Step 7: Arrange the discs on a baking sheet and bake them at 350°F for 11-12 minutes. The centers may look slightly wet—this is perfect. Avoid overbaking. Let the cookies cool completely on the pan before decorating.

Step 8: To make the chocolate ganache, place the semi-sweet chocolate chips in a medium, heat-safe bowl.

Step 9: Heat the heavy cream in a microwave-safe container for 30-45 seconds until it starts to bubble. Alternatively, heat on the stove until steaming, but not boiling.

Step 10: Pour the hot cream over the chocolate chips without stirring. Press down the chips with a fork to ensure they are fully covered. Let sit for 3 minutes.

Step 11: After resting, stir the mixture with a fork until smooth and creamy. If not fully melted, carefully microwave in 10-second intervals at 50% power, stirring between each, until perfectly smooth.

Step 12: Spoon about 1 tablespoon of ganache onto each cooled cookie, then top with rainbow chip sprinkles.

Step 13: Refrigerate the decorated cookies for 30-60 minutes to allow the ganache to harden.

Step 14: For the best texture and flavor, keep the cookies refrigerated. They develop an even fudgier texture when chilled but can also be stored at room temperature for up to 2 days.

Tips & Variations

Use a stainless steel cookie scoop to keep dough portions uniform for even baking.

If you prefer a less rich cookie, swap dark cocoa powder for natural cocoa powder.

For extra texture, fold in chopped nuts along with the chocolate chips.

Try different sprinkles or edible glitter for a customized festive look.

Storage

Store these cookies in an airtight container in the refrigerator for up to one week to maintain their fudgy texture. If you prefer, keep them at room temperature in a sealed container for up to two days, but refrigeration is recommended to keep the ganache firm. To serve chilled cookies softer, let them sit at room temperature for 10 minutes before eating.

FAQs

Can I make the cookie dough ahead of time?

Yes, you can prepare the dough and refrigerate it for up to 24 hours before baking. This can help intensify the flavors and improve texture.

What if I don’t have light corn syrup?

If you don’t have light corn syrup, you can substitute with an equal amount of honey or maple syrup. This will slightly alter the flavor but still provide the chewy texture.
