Ingredients for hershey blossom cookie

Classic ingredients transformed into nostalgic cookies with signature swirls and melty centers.

The butter and sugars form the foundation—European-style unsalted butter yields superior flavor, while superfine sugar ensures a smoother dough. For the chocolate and marshmallow filling, Hershey's semi-sweet bars provide that iconic taste, and miniature marshmallows melt perfectly without clumping. King Arthur or Gold Medal flour delivers consistent results, though any all-purpose works. The vanilla extract should be pure, not imitation—McCormick or Nielsen-Massey brands are reliable choices. All ingredients should be measured precisely, as the balance between dry and wet components determines the signature texture.

No superfine sugar? Pulse granulated sugar in a food processor for 30 seconds to achieve a similar texture. Substitute white chocolate for milk chocolate if preferred, though the flavor profile will differ slightly. For a vegan option, replace eggs with 2 tbsp flaxseed meal + 6 tbsp water, mixed and rested for 5 minutes. The baking powder must be fresh—test by mixing 1 tsp with water; it should bubble vigorously. If your marshmallows are too large, pulse them briefly in a food processor to achieve uniform size. The heavy whipping cream should be cold but not frozen to whip properly—this prevents butter separation in the final dough.

Store dough in an airtight container in the refrigerator for up to 48 hours, though it's best used immediately for optimal texture. Baked cookies keep their signature crisscross pattern and crisp edges for 5 days at room temperature, wrapped tightly in parchment. For longer storage, freeze shaped cookies on a tray before transferring to a bag—3 months maximum. Reheat in a 350°F oven for 2-3 minutes to restore that fresh-from-the-oven gooeyness. The confectioners' sugar dusting should be done immediately after baking to prevent moisture absorption.

Step-by-step instructions for Hershey Blossom cookies

Master the art of these decadent cookies with a perfect balance of crispy edges and gooey centers.

In a stand mixer fitted with the paddle attachment, beat the 1 cup unsalted butter on medium speed until completely softened, about 1-2 minutes. Add the 1 cup granulated white sugar and 0.5 cup packed brown sugar, then beat on medium speed for 3-4 minutes until the mixture is light and fluffy, nearly doubling in volume.

This creaming process incorporates air into the dough, which creates the signature crackly tops and helps achieve that perfect spread. Scrape down the sides of the bowl with a rubber spatula to ensure even mixing. The mixture should be pale and thick, leaving a distinct trail when the beaters are lifted.

Add the 2 whole large eggs, one at a time, mixing on low speed after each addition until fully incorporated. Then add the 2 teaspoons pure vanilla extract and mix for an additional 30 seconds until the mixture is smooth and homogeneous.

This step ensures the eggs are fully emulsified with the butter and sugars, creating a stable dough base. Avoid overmixing at this stage, as it can develop gluten and result in tougher cookies. The mixture should be thick but still pourable—if it looks too stiff, add 1 teaspoon of milk to loosen it slightly.

In a separate bowl, whisk together the 2.5 cups all-purpose flour, 1 teaspoon baking powder, and 0.5 teaspoon diamond crystal kosher salt. Gradually add the dry ingredients to the butter mixture, mixing on low speed until just combined. Avoid overmixing to maintain a tender texture.

Remove the bowl from the mixer and fold in the 8 ounces chopped Hershey's milk chocolate bars using a silicone spatula. The chocolate should be evenly distributed throughout the dough, with no large clumps remaining. If the dough feels too dry, add 1 tablespoon of milk to help bind it together.

In a small bowl, combine the 1.5 cups miniature marshmallows and 0.5 cup heavy whipping cream. Microwave in 30-second intervals, stirring between each interval, until the marshmallows are completely melted and the mixture is smooth. Let the mixture cool slightly but remain spreadable.

Divide the chocolate dough into 4 equal portions and flatten each into a 6-inch circle on a piece of parchment paper. Spread 1 tablespoon of the marshmallow mixture down the center of each circle, then fold the edges of the dough over the filling to completely enclose it. Roll each filled dough circle into a log, about 1-inch in diameter, and twist gently to create a rope-like shape.

Preheat your oven to 350°F and line two baking sheets with parchment paper. Place the twisted dough logs on the prepared sheets, spacing them 2 inches apart to allow for spreading. Bake for 12-14 minutes until the edges are golden brown and the tops are set but still slightly soft.

Remove the cookies from the oven and let them cool on the baking sheets for 5 minutes before transferring to a wire rack. While still warm, dust the tops generously with 0.25 cup confectioners' sugar using a fine-mesh sieve. Allow the cookies to cool completely before serving to ensure the marshmallow filling sets properly.

Once fully cooled, slice each cookie log into 1-inch pieces using a serrated knife. The warm, gooey marshmallow center will contrast beautifully with the crispy chocolate exterior. Store any leftovers in an airtight container at room temperature for up to 3 days, or freeze for up to 1 month for maximum freshness.

The result should be a cookie with a crispy, slightly crispy exterior, a soft, chewy interior, and a luscious marshmallow swirl that melts deliciously with each bite. Serve with a glass of cold milk for the ultimate indulgence.

Storing and reheating your hershey blossom cookie

Room Temp Storage

Keep freshly baked Hershey Blossom cookies at room temperature in an airtight container for up to 5 days. I use a Rubbermaid Brilliance container with a tight-sealing lid to maintain freshness. Store them in a single layer to preserve their signature crisscross pattern and crisp edges.

The marshmallow filling stays gooey when protected from moisture—just avoid stacking too many layers to prevent squishing. 🍪

Refrigerator Refresh

If you notice the marshmallow centers starting to dry out, revive them by placing the cookies on a baking sheet and warming in a 250°F oven for 3-4 minutes. This gentle heat reactivates the gooeyness without overcooking the chocolate.

I also recommend wrapping individual cookies in parchment paper before refrigerating for up to 1 week—this prevents them from sticking together. 💫

Freezer Magic

For long-term storage, freeze shaped but unbaked cookie logs on a parchment-lined tray for 1 hour before transferring to a freezer bag. This prevents moisture buildup that causes soggy textures. Thaw in the fridge overnight, then bake as directed.

The texture remains crisp after freezing, though the marshmallow filling may need a 1-minute warm-up in the oven to restore its melt-in-your-mouth quality. 🧊

Reheating Secrets

For that fresh-from-the-oven experience, reheat cookies at 350°F for 2-3 minutes until the edges are warm and slightly crisp. I use a wire cooling rack on a baking sheet to avoid soggy bottoms.

Microwave reheating is possible but risks melting the chocolate unevenly—if you must, use 10-second bursts on low power and check frequently. Always dust with confectioners' sugar after reheating for that restaurant-quality finish. ✨

Serving Suggestions

Serve Hershey Blossom cookies at room temperature with a glass of whole milk or vanilla chai latte to enhance the chocolate-marshmallow flavors. For parties, arrange them on a wooden board with dark chocolate shavings for an elegant presentation.

The contrast of warm cookies with cold milk creates the perfect sensory experience—just be prepared for them to disappear quickly! 🥛
