Serves: 6
Makes: 12 brownies
Hands-on time: 15 minutes
Total time: 30 minutes (plus cooling time)


  • Olive oil cooking spray
  • 4 oz dark chocolate (70% cocoa or greater)
  • 3 tbsp organic unsalted butter
  • 2 large eggs, room temperature
  • 1/3 cup organic evaporated cane juice (TRY: Florida Crystals Organic Cane Sugar)
  • 1 tsp pure vanilla extract
  • 1/3 cup light spelt flour
  • 2 tbsp unsweetened cocoa powder
  • 3 tbsp natural unsalted smooth peanut butter, room temperature


  1. Preheat oven to 350°F. Mist an 8-inch square baking dish with cooking spray and line with parchment paper, leaving 2 inches hanging over 2 opposing sides.
  2. In a large microwave-safe bowl, combine chocolate and butter. Microwave on 50% power (low) for 30 seconds. Stir and cook for 30 more seconds; repeat until chocolate and butter melt, being careful not to overcook. (Alternatively, bring a pot of water to a very gentle simmer; place a stainless steel bowl over pot and add chocolate and butter to bowl. Cook, stirring, until melted, 2 to 3 minutes.)
  3. Stir in eggs, cane juice and vanilla until combined. Add flour and cocoa powder and stir until just incorporated and no white streaks remain; do not over-mix.
  4. Pour into baking dish, spreading evenly with a rubber spatula. Working in small dollops, dot surface of batter with peanut butter. With a butter knife, swirl peanut butter through batter.
  5. Bake until a toothpick comes out with only a few crumbs when inserted in center, 15 to 18 minutes. Transfer to a wire rack and let cool completely, about 20 minutes. Remove brownies from dish by lifting parchment paper. Slice into 12 pieces.

    I just finished making this recipe – it does not yield the amount shown. I initially poured the batter into an 8″ baking pan and it only spread 1/4″ thick. I transfered the batter into silicon muffin cups and it turned out OK
