A Sweet Memory: The Love for Heavenly Hash Brownies

There’s something magical about biting into a freshly baked brownie—especially when it’s packed with gooey marshmallows, crunchy nuts, and a rich, fudgy texture. I remember the first time I tried Heavenly Hash Brownies—I was at my grandmother’s house, watching her effortlessly mix chocolate batter, her kitchen filled with the irresistible scent of cocoa and toasted nuts. She handed me a warm square, and with that first bite, I was hooked.

Fast forward to today, and I still find myself craving that same decadent experience. Whether you’re a die-hard chocolate lover or someone looking for a nostalgic dessert, these brownies are a must-try. And the best part? They’re ridiculously easy to make!

So, let’s dive into what makes Heavenly Hash Brownies so special and how you can make them perfectly at home.

What Are Heavenly Hash Brownies?

At their core, Heavenly Hash Brownies are a delightful combination of classic fudgy brownies topped with marshmallows, nuts, and a luscious chocolate glaze. The name “Heavenly Hash” comes from the famous Heavenly Hash candy, a vintage confection known for its mix of chocolate, marshmallows, and nuts.

These brownies offer:

  • A rich chocolate base that’s perfectly dense and chewy.
  • Melted marshmallows that create an irresistibly soft and gooey texture.
  • Crunchy nuts that add a satisfying bite.
  • A smooth chocolate glaze that brings everything together.

This recipe isn’t just any brownie—it’s a next-level chocolate experience.

A Brief History of Heavenly Hash

The term “Heavenly Hash” has been around for over a century, originally used to describe a marshmallow-chocolate-nut candy popular in the early 1900s. Over time, the combination found its way into different desserts—ice creams, cakes, and, of course, Heavenly Hash Brownies.

Fun fact: Heavenly Hash ice cream was one of the first commercial ice cream flavors to mix chocolate with marshmallows and nuts. If you’ve ever had it, you’ll understand why this flavor combination is so iconic!

The brownie version took off in the mid-20th century as home bakers experimented with making their chocolate treats even more indulgent. Today, Heavenly Hash Brownies remain a favorite, offering a perfect balance of textures and flavors.

Step-by-Step Recipe for Heavenly Hash Brownies

Now that we’ve covered what makes Heavenly Hash Brownies so special, let’s get into the actual recipe. This step-by-step guide will help you achieve the perfect texture—chewy, fudgy, gooey, and crunchy—all in one bite!

Step 1: Preparing the Brownie Base

A good brownie starts with a solid base. The goal is to create a rich, fudgy texture that holds up well against the marshmallows and nuts.

Instructions:

  1. Preheat & Prepare – Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper for easy removal.
  2. Melt the Butter & Chocolate – In a heatproof bowl, melt butter and semi-sweet chocolate chips over a double boiler or microwave in short bursts. Stir until smooth.
  3. Mix the Sugars & Eggs – In a separate bowl, whisk together granulated sugar, brown sugar, eggs, and vanilla extract until light and creamy.
  4. Combine Wet & Dry Ingredients – Slowly add the melted chocolate mixture to the sugar-egg mixture, stirring continuously. Then sift in flour, cocoa powder, baking powder, and salt. Mix until just combined—don’t overmix!
  5. Bake to Perfection – Pour the batter into the prepared pan and smooth out the top. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.

Pro Tip: For extra fudgy brownies, slightly underbake them and let them cool completely before cutting.

Step 2: Adding the Marshmallows and Nuts

This is where Heavenly Hash Brownies get their signature texture!

Instructions:

  1. Layer the Marshmallows – As soon as the brownies come out of the oven, immediately sprinkle mini marshmallows over the hot surface. The heat will start to soften them slightly.
  2. Add the Crunch – Sprinkle chopped walnuts or pecans evenly over the marshmallows. If you love extra crunch, lightly press them down so they stick better.

Step 3: Creating the Chocolate Glaze

No Heavenly Hash Brownie is complete without a silky, rich chocolate glaze.

Instructions:

  1. Heat the Heavy Cream – In a small saucepan, warm heavy cream over low heat until it starts to steam (but don’t let it boil).
  2. Melt the Chocolate – Pour the hot cream over chopped dark chocolate in a bowl. Let it sit for a minute, then stir until smooth.
  3. Drizzle Over Brownies – Pour the warm glaze over the marshmallow-nut topping, ensuring an even coating. Use a spatula to gently spread it if needed.
  4. Set the Brownies – Let them cool at room temperature or place them in the refrigerator for at least 30 minutes to set before slicing.

Pro Tip: For an extra glossy finish, add a teaspoon of butter to the chocolate glaze!

Expert Tips for Perfect Heavenly Hash Brownies

Use Fresh Marshmallows – Stale marshmallows won’t melt properly and might turn rubbery.
Don’t Overbake – The key to fudgy brownies is baking just until the edges are set but the center is slightly soft.
Chill Before Cutting – Let the brownies cool completely before slicing for clean, perfect squares.

“Brownies should never be rushed—greatness takes time.”

Common Problems & How to Fix Them

Even the best bakers face challenges, but don’t worry—I’ve got solutions!

Problem: Brownies Turn Out Too Dry

Fix: This happens when they’re overbaked. Next time, check them 5 minutes before the recommended time.

Problem: Marshmallows Melt Too Much or Burn

Fix: Add marshmallows as soon as the brownies come out of the oven, but don’t return them to the oven.

Problem: Chocolate Glaze Isn’t Smooth

Fix: Make sure the chocolate is chopped finely before adding hot cream. If lumps remain, microwave for 10 seconds and stir.
