When the weather is sweltering, and you crave something chocolate, the Instant Pot is an excellent oven alternative that leaves your kitchen cool and comfortable. This recipe makes a rich, nut-studded batch of scrumptious brownies that you slice and serve by the wedge. The Instant Pot also saves precious oven space when you're making a big dinner and your racks are filled with other dishes.

Add 15 to 18 minutes to the total cooking time to allow for pressure buildup and release. If you are using another brand or type of pressure cooker, consult the manufacturer's manual and adjust accordingly.

Cut the brownies up and use the pieces in a chocolate brownie sundae or enjoy slices topped with the rich chocolate ganache and chopped nuts.

Ingredients

  • 8 tablespoons butter (unsalted, softened)
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 1/2 teaspoons vanilla extract
  • 3/4 cup all-purpose flour (3 1/2 ounces)
  • 1/2 cup unsweetened cocoa powder (natural, not Dutch process)
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 2/3 cup semisweet chocolate chips
  • 1/2 cup chopped pecans (plus more for garnish, if desired)
  • For the Ganache:
  • 3 ounces semisweet chocolate (broken into pieces)
  • 1/4 cup heavy cream

Steps to Make It

  1. Gather the ingredients.

  2. Spray a 7-inch round baking pan with nonstick cooking spray. Cut a sheet of parchment paper to fit into the bottom of the pan and spray it lightly.

  4. Add the eggs, one at a time, beating well after each addition. Beat in the vanilla.

  5. In a separate bowl, combine the flour, cocoa powder, baking powder, and salt; blend thoroughly with a spoon or whisk. Add the dry ingredients to the first mixture and beat on low speed just until blended.

  8. Add 1 1/2 cups of water to the Instant Pot inner pot and put a baking sling in the pot. (If you don't have a silicone sling make one by putting a trivet in the pot, and putting in a long, folded sheet of foil; this will make it easier to lift the pan out when the brownies are ready.) Place the pan on the trivet or sling.

  9. Secure the Instant Pot lid and ensure the steam release valve is in the sealing position. Choose the pressure cook function (or manual on older models), high pressure, and set the time to 40 minutes. When the time is up, let the pressure release naturally for 10 minutes. Carefully turn the valve to venting to release the remaining steam. Lift the pan of brownies out, remove the foil, and set them on a rack to cool.

  10. When the brownies are cool, prepare the chocolate ganache glaze. Place the semisweet chocolate in a bowl and set it aside. Pour the heavy cream into a saucepan. Place the pan over medium heat and bring the cream to a boil. Pour the cream over the semisweet chocolate; stir until the chocolate has melted and the mixture is smooth.
