This simple pistachio brownies recipe has big, surprising flavor thanks to pistachio butter. With a chewy, brownie texture and silky ganache frosting, this might be become your new favorite blonde brownie.


Units Scale
  • 6 ounce Bag of Southern Groves Shelled Pistachios
  • 6 tbsp Unsalted butter, (melted)
  • 3/4 cup Light brown sugar, (packed)
  • 1 cup Baker’s Corner All Purpose Flour
  • 1 tsp Baking powder

Chocolate Ganache

  • 1/2 cup Heavy whipping cream
  • 6 ounces Semi-Sweet Chocolate (1 cup chocolate chips or chunks)


  1. Measure out 3 tbsp of pistachios, finely chop, and set aside for garnish.
  2. Add the rest of the pistachios to a food processor bowl. Pulse continuously until smooth consistency is like peanut butter, about 4-5 minutes.
  3. Measure out ½ cup of pistachio butter, which should be about the whole amount. Set aside.
  4. In a mixing bowl, add the melted butter and sugar. Use an electric mixer and mix until well combined and smooth, about 1 minute.
  5. Add the pistachios butter to the bowl and continue mixing until smooth, about 1 minute. 
  6. Add the egg to the bowl and mix well. 
  7. Add the flour and baking powder and mix on low speed until fully combined. 
  8. Spray an 8 x 8 square baking pan with nonstick cooking spray. Then line with piece of parchment paper, leaving two edges overhanging.
  9. Scoop the dough into the prepared pan and press it with your fingers to create an even smooth layer. 
  10. Bake for 20-22 minutes, until edges and middle are golden brown. Let cool.
  11. Prepare the chocolate ganache by heating the cream in a saucepan over low heat until rapidly steaming, but not simmering, about 10 minutes. Add the chocolate chips to a heat safe bowl then pour the hot cream over the chocolate. Let sit for one minute then stir until smooth, combined and glossy. 
  12. Let ganache sit for 30 minutes. (This step is optional.)
  13. Pour chocolate ganache over cooled bars and spread evenly to fully cover brownies. Sprinkle reserved, chopped pistachios on top. Chill in the fridge until set, at least 4 hours. 
  14. Gently wiggle the bars out of the pan using the two sides of parchment paper. Set on a cutting board. Use a sharp knife to cut 12-16 bars.


  • 1/2 cup of peanut butter or other nut butter can be substituted for pistachio butter. Flavor will be different.
  • If the baked blonde brownies are not quite cool enough when it's time to pour on the ganache, put them in the freezer for 15 minutes to cool them down.
