The Heavenly Hash Brownies Recipe

Heavenly Hash Brownies Recipe

Ingredients:

For the Brownie Base:

  • 1 cup unsalted butter (melted)
  • 1 1/2 cups granulated sugar
  • 1 cup brown sugar (packed)
  • 4 large eggs
  • 1 tsp vanilla extract
  • 1 cup all-purpose flour
  • 1 cup unsweetened cocoa powder
  • 1/2 tsp salt
  • 1 tsp baking powder

For the Heavenly Hash Topping:

  • 2 cups mini marshmallows
  • 1 cup semisweet or dark chocolate chunks
  • 1 cup chopped pecans or walnuts (optional, or substitute with almonds for a twist)

Step-by-Step Instructions:

Step 1: Preheat the Oven and Prepare the Pan

  1. Preheat your oven to 350°F (175°C).
  2. Grease a 9x13-inch baking pan or line it with parchment paper to ensure easy removal of the brownies after baking.

Step 2: Make the Brownie Base

  1. In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until well combined and smooth.
  2. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
  3. In a separate bowl, sift together the flour, cocoa powder, salt, and baking powder. Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix—the batter should be thick and rich.

Step 3: Bake the Brownies

  1. Pour the brownie batter into the prepared pan and spread it evenly with a spatula.
  2. Bake the brownies in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs (you don’t want to overbake—fudgy is key!).

Step 4: Add the Heavenly Hash Topping

  1. Remove the brownies from the oven and immediately sprinkle the mini marshmallows, chocolate chunks, and chopped nuts evenly over the top.
  2. Return the pan to the oven for an additional 3-5 minutes, just until the marshmallows puff up and begin to turn golden brown and the chocolate chunks start to melt.

Step 5: Cool and Serve

  1. Once the heavenly hash topping is melted and gooey, remove the pan from the oven. Allow the brownies to cool in the pan for at least 15-20 minutes before cutting into squares. This gives the toppings a chance to set and makes slicing easier.

Tips for the Best Heavenly Hash Brownies:

  • Don’t overbake the brownies. You want them to remain fudgy and moist, so be sure to pull them out of the oven when they’re still slightly underdone in the center.
  • Customize the toppings: You can add other fun ingredients to the heavenly hash topping like shredded coconut, caramel bits, or even peanut butter chips for extra flavor.
  • For clean cuts: Use a sharp knife and wipe it clean between slices to get neat, beautiful brownie squares, especially with the gooey marshmallow topping.

Why These Brownies Are Called "Heavenly":

The combination of a rich, fudgy brownie base topped with gooey marshmallows, melting chocolate, and crunchy nuts makes these brownies irresistible. The textures—soft, chewy, and crunchy—make every bite pure bliss. They’re reminiscent of a classic Rocky Road flavor but baked into a brownie for a more decadent experience.

Serving Suggestions:

  • Warm and gooey: Serve the brownies slightly warm with a scoop of vanilla ice cream for the ultimate indulgence.
  • Room temperature: These brownies are just as delicious at room temperature and make a perfect treat for parties or family gatherings.
  • Store leftovers: If you manage to have leftovers, store them in an airtight container at room temperature for up to 3 days.

Final Thoughts:

These Heavenly Hash Brownies are the perfect dessert for chocolate lovers who want something beyond a basic brownie. With their gooey marshmallow and nut topping, each bite is a mix of rich chocolate, chewy sweetness, and crunchy goodness. Whether you're making them for a special occasion or just a weeknight treat, these brownies will surely be a hit.

Enjoy your slice of heaven!
