Description

Deliciously moist pumpkin spice brownies with a smooth pumpkin buttercream frosting, perfect for autumn treats and holiday gatherings.


Ingredients

Scale

For the Brownies

  • 1/2 cup granulated sugar
  • 1/4 cup unsalted butter
  • 2 tablespoons whole milk
  • 1 1/2 cups milk chocolate chips
  • 2/3 cup flour
  • 1/2 teaspoon pumpkin spice
  • 1/4 teaspoon baking soda
  • 1/2 teaspoon salt
  • 2 eggs
  • 1 teaspoon vanilla extract

For the Frosting

  • 3/4 cup unsalted butter, softened
  • 3 tablespoons pumpkin puree
  • 2 cups powdered sugar
  • 1 1/2 teaspoons pumpkin pie spice
  • 1 teaspoon vanilla extract
  • A pinch of kosher salt


Instructions

  1. Preheat Oven and Prepare Pan: Preheat the oven to 325 F and prepare an 8×8 inch baking dish by greasing or lining it with parchment paper.
  2. Make Chocolate Mixture: In a sauce pot, combine milk, butter, and granulated sugar and heat until simmering. Remove from heat and stir in the milk chocolate chips until smooth. Allow this mixture to cool slightly.
  3. Mix Dry Ingredients: In a separate bowl, whisk together the flour, pumpkin spice, baking soda, and salt. Set aside.
  4. Combine Wet and Dry: Whisk the eggs and vanilla extract into the cooled chocolate mixture. Gradually add the dry ingredients into the batter, mixing gently with a spatula until just combined.
  5. Bake the Brownies: Pour the batter into the prepared baking dish, spreading evenly. Bake for 30 minutes or until a toothpick inserted in the center comes out clean. Remove and let the brownies cool completely.
  6. Prepare Frosting: In a stand mixer fitted with a whisk attachment, combine the softened butter and pumpkin puree. Add pumpkin pie spice, vanilla extract, and a pinch of kosher salt. Use a spatula to scrape down the sides, then gradually incorporate powdered sugar until a smooth buttercream forms.
  7. Frost Brownies: Once the brownies are completely cool, spread the pumpkin buttercream frosting evenly over the top. Cut into 9 squares and serve.

Notes

  • Use whole milk for best texture, but you can substitute with any milk of choice.
  • Ensure brownies are completely cooled before frosting to prevent melting.
  • For a dairy-free version, use plant-based butter and milk alternatives.
  • Adjust the pumpkin spice and pie spice amounts to your taste preference.
  • Store brownies in an airtight container for up to 3 days at room temperature or refrigerate for up to a week.
