Total time: 1 h
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); 1 ¼ 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 (e.g., Hershey’s Special Dark)

1 ¼ cups all-purpose flour

¾ cup semi-sweet chocolate chips (for ganache)

¼ cup heavy cream (for ganache)

Rainbow chip sprinkles (for decorating)

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 light and fluffy.

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

Step 4: Stir in baking soda and salt, mixing briefly until blended.

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

Step 6: Scoop dough into ¼ cup portions and roll into balls. Gently flatten each ball into a ½ inch thick disc to help them spread evenly during baking.

Step 7: Arrange cookies on a baking sheet and bake for 11-12 minutes. Don’t overbake; centers may look slightly wet but will firm up as they cool.

Step 8: Let cookies cool completely before decorating.

Step 9: To make chocolate ganache, place chocolate chips in a medium heat-safe bowl. Heat heavy cream until bubbling, then pour it over the chips. Let sit for 3 minutes, then stir until smooth. If needed, microwave briefly in short bursts to melt fully.

Step 10: Spoon about 1 tablespoon of ganache onto each cooled cookie and sprinkle with rainbow chip sprinkles. Refrigerate for 30-60 minutes to allow ganache to set.

Step 11: Enjoy your fudgy cookies chilled for the best texture, or keep at room temperature for up to 2 days.

Tips & Variations

Use a cookie scoop for even-sized cookies to ensure uniform baking.

Light corn syrup adds chewiness but can be substituted with honey or golden syrup if unavailable.

For an extra fudgy texture, slightly underbake and allow cookies to finish setting on the warm baking sheet.

Try adding chopped nuts or replacing rainbow sprinkles with crushed peppermint for a seasonal twist.

Storage

Store cooled cookies in an airtight container in the refrigerator for up to one week to maintain fudginess and freshness. You can also keep them at room temperature for up to 2 days, but refrigeration is recommended if you want the ganache to stay firm. To reheat, allow cookies to come to room temperature or microwave briefly for a warm, gooey treat.

FAQs

Can I use regular corn syrup instead of light corn syrup?

Light corn syrup is preferred for its mild flavor and texture, but you can substitute it with honey or golden syrup in the same quantity. Avoid high fructose corn syrup as it may affect the texture.

How do I know when the cookies are done baking?

The cookies are ready when the edges look set but the centers may still appear slightly wet. They will firm up as they cool on the baking sheet, so avoid overbaking to keep them fudgy.
