Hershey Bar Cookies Recipe: Fudgy Chocolate Chunks and Crispy Edges

This Hershey Bar cookie recipe delivers the perfect balance of crispy edges and fudgy chocolate chunks that taste like a warm hug from childhood. 💛 The secret lies in using chopped Hershey bars directly in the dough, ensuring every bite packs that signature milk chocolate flavor with just the right texture contrast.

I've perfected this recipe over years of baking experiments, and it never fails to impress—whether you're making them for holidays or a simple treat night.

The process is straightforward but requires attention to detail for that ideal texture. You'll need to mix the dough just until combined (overmixing makes cookies tough), then chill it for 30 minutes before baking. This resting time prevents excessive spreading while ensuring crispy edges and a tender center.

The key is baking at 350°F for 10-12 minutes—just enough time for the chocolate to soften but not melt completely.

What you'll end up with is a batch of cookies that looks like they came straight from a bakery: golden-brown edges with visible chocolate chunks peeking through. The aroma of melting chocolate fills your kitchen, and each bite delivers that perfect balance of crispy, chewy, and rich chocolate goodness.

These cookies stay fresh for days, making them ideal for gifting or keeping on hand for spontaneous cravings.

For extra indulgence, press a few extra chocolate chips on top before baking, or drizzle melted chocolate over the cooled cookies. The possibilities are endless, but the classic version always hits the spot. Let's get baking—your kitchen will smell amazing in no time.

Ingredients for hershey bar cookie

Just nine ingredients transform into nostalgic cookies with crispy edges and melty chocolate centers.

The Hershey bars are non-negotiable here—Hershey's Milk Chocolate has that signature taste. Grab the full-size bars (not the mini ones) at Walmart or Target—they're cheaper than the bakery section. Chop them into even 1/2-inch pieces for consistent melting. I like to use a food processor for speed, but a knife works too. For the flour, King Arthur or Gold Medal brands give the best texture. If you're in a pinch, Bob's Red Mill all-purpose works fine. The butter? Land O'Lakes unsalted is my go-to—it's reliable and widely available.

No Hershey bars? Dutch-processed cocoa powder plus extra sugar gets you close, but the texture won't be identical. Swapping chocolate chips for the chopped bars? Use 1.5 cups chips instead—chips melt faster and won't give the same fudgy pockets. Short on vanilla? Vanilla bean paste adds depth. The baking soda is crucial—don't use powder. For a nutty twist, fold in 1/2 cup chopped walnuts with the chocolate chips. And if you're feeling fancy, add a pinch of espresso powder to enhance the chocolate flavor—trust me, it works.

These cookies keep for 5-7 days in an airtight container, but they'll taste freshest within the first 2 days. For longer storage, freeze the dough balls (before baking) on a tray, then transfer to a bag for up to 3 months. Bake straight from frozen, adding 1-2 extra minutes. Pro tip: Press a few extra chocolate chips on top before baking—they melt just enough to create those gorgeous chocolate pockets. Leftovers? Reheat in the microwave for 10 seconds to revive the crispy edges.

Step-by-step instructions for Hershey bar cookies

Here's how to make cookies with that perfect balance of fudgy centers and crispy edges.

Break the 12 oz Hershey Milk Chocolate Bars into ½-inch pieces using a sharp knife or kitchen shears. I like to work on a microwave-safe plate for easy cleanup. Place the chocolate pieces in a microwave-safe bowl and microwave in 30-second bursts on medium-high power, stirring between each interval, until completely melted and smooth. The chocolate should be fully liquid with no streaks—this ensures even distribution when you fold it into the dough.

Here's the thing—don't overheat the chocolate. If it starts to look grainy or separates, add a tiny drop of the unsalted butter (cubed) to help smooth it out. Once melted, let it cool for 5 minutes to room temperature before using. This prevents the butter in the dough from melting too quickly when you mix everything together.

In a large mixing bowl, combine the 1 cup unsalted butter (cold and cubed) and 1 cup granulated sugar. Using a hand mixer or stand mixer fitted with the paddle attachment, beat on medium speed for 2-3 minutes until the mixture is light in color and fluffy. You'll see it nearly double in volume and leave clean streaks on the bowl when you lift the beaters.

This creaming process is what creates those beautiful crackly tops on your cookies. I press down on the butter mixture with my fingers occasionally to check for readiness—it should feel airy and almost like whipped cream. If it's still grainy, keep beating for another 30 seconds. Don't rush this step; patience here makes all the difference in texture.

Add the 2 whole large eggs (room temperature) one at a time, mixing on low speed for 30 seconds after each addition until fully incorporated. Then add the 1 tsp vanilla extract and mix for another 10 seconds. The mixture might look slightly curdled, but that's normal—the eggs will come together when you add the dry ingredients.

In a separate bowl, whisk together the 2.5 cups all-purpose flour, 0.5 tsp baking soda, and 0.5 tsp salt. Gradually add this to the wet ingredients, mixing on low speed for 30-45 seconds until just combined. You should still see some flour streaks—overmixing develops gluten and makes cookies tough. Stop mixing as soon as the dough comes together.

Remove the bowl from the mixer and gently fold in the cooled melted Hershey chocolate and 1 cup semisweet chocolate chips using a silicone spatula. Be careful not to overmix—just swirl the dough until the chocolate is evenly distributed. The dough will be thick and sticky, but that's exactly what we want for those fudgy centers.

Cover the bowl with plastic wrap and refrigerate for at least 1 hour (or up to 24 hours). Chilling the dough is crucial—it firms up the butter so the cookies hold their shape when baking, and it prevents excessive spreading. The cold dough also means the chocolate stays melted in the center for that gooey texture. I like to press the dough against the side of the bowl before covering to create a smooth surface for scooping.

Preheat your oven to 350°F and line two baking sheets with parchment paper. Using a cookie scoop or tablespoon, drop dough balls onto the prepared sheets, spacing them 2 inches apart—they'll spread. I use a 1.5-tablespoon scoop for cookies that are about 2 inches wide when baked.

Bake for 10-12 minutes until the edges are golden brown but the centers still look slightly underdone. The cookies will continue cooking on the hot pan after you remove them from the oven. Don't overbake—you want that perfect balance of crispy edges and fudgy centers. Let them cool on the baking sheet for 5 minutes before transferring to a wire rack to set completely.

Essential equipment for perfect results

Mixing Essentials

Start with a stand mixer like the KitchenAid Artisan Series for creaming butter and sugar—its powerful motor handles the job efficiently. For hand mixers, I recommend Cuisinart’s Power Advantage for consistent results.

Use the paddle attachment (not whisk) to achieve that light, fluffy texture. A medium-sized mixing bowl (6-8 quart capacity) gives enough room for the dough to expand without spilling. 💛

Chocolate Prep Tools

For chopping Hershey bars, a sharp chef’s knife or kitchen shears works best—avoid dull blades that tear the chocolate. I prefer a microwave-safe glass bowl for melting, as it heats evenly and prevents scorching.

A silicone spatula helps fold melted chocolate into dough without adding extra fat. For precision, a digital kitchen scale ensures accurate measurements when chopping chocolate pieces.

Baking Sheet Setup

Use heavy-duty baking sheets like Nordic Ware’s Half-Sheet Pans—they distribute heat evenly and prevent warping. Line them with parchment paper from If You Care (bleach-free) for easy release. A cookie scoop (like OXO’s Good Grips) ensures uniform dough balls, while tongs help transfer hot cookies to racks.

For extra crispy edges, I place sheets on the middle rack of the oven.

Chilling and Storage

An airtight container from Rubbermaid keeps dough fresh in the fridge for up to 24 hours. For long-term storage, quart-sized freezer bags from Ziploc work best—squeeze out air to prevent freezer burn.

A wire cooling rack (like Amazon Basics) prevents soggy bottoms while cooling. Label containers with masking tape and a marker to track freshness.

Decorating Extras

For finishing touches, keep semisweet chocolate chips (like Hershey’s Cocoa Kisses) and a pastry brush handy for drizzling melted chocolate. A small offset spatula helps spread toppings evenly.

For texture contrast, crushed peppermint candies or toasted coconut flakes add fun variations. Store extras in small glass jars with tight-sealing lids for easy access.
