Instructions

Brownie Base (from Mike Johnson's book Even Better Brownies)

  • Preheat the oven to 350 F /180 C. Line an 8 x 8-inch pan with parchment paper then grease with butter or nonstick cooking spray and set aside.
  • Heat the butter and 3/4 cup (130g) chocolate chips in a heatproof bowl in the microwave in 30 second intervals. Stir between intervals and repeat until melted and smooth. Stir in the sugar, vanilla, and espresso powder.
  • Beat the eggs into the chocolate mix one at a time. Add the flour, cocoa powder and baking powder. Stir until just combined. Stir in the remaining 1/4 cup (45 grams) of chocolate chips.
  • Evenly spread the mixture into the prepared pan. Bake for 28-30 minutes or until the brownies are just set.

Topping (from Mike Johnson's book Even Better Brownies)

  • Place the the chopped chocolate and butter in a small microwave-safe bowl. Heat in 15 second intervals, stirring between each interval until melted and smooth.
  • Pour the mixture over the top of the warm brownies and then sprinkle with chopped pretzels, potato chips, Oreos® and M&M's® on top.
  • Let the brownies cool completely before slicing.
  • Cover and store leftover brownies in an airtight container at room temperature for 3-4 days.

Notes

These brownies can be topped with any of your favorite snacks - just make sure you don't add more than 1 cup (240g) of chopped toppings! Peanut butter cups, honey-roasted peanuts, yogurt-covered pretzels or toasted coconut would also taste great!
