• Preheat the oven to 350 degrees F. Spray an 8×8-inch baking dish with nonstick spray. In a small bowl, whisk together the flour, cocoa powder, baking powder and salt. Set it aside.
• In a large bowl, whisk together the melted butter and the sugar. Once smooth, whisk in the egg, sour cream/yogurt, milk and vanilla extract. Stir the mixture until it is a smooth batter. Gradually add in the dry ingredients and stir until just combined. Stir in the zucchini and chocolate chips. Spread the batter into the greased pan. Bake for 30 to 35 minutes, then remove from the oven and let cool in the pan for 20 minutes.

candied pistachios & chocolate topping

• Spread the pistachios out on a baking sheet layered with parchment paper. Mix together the hot water and brown sugar until the sugar is dissolved, then toss the pistachios with the sugar liquid. Roast the nut at 350 degrees F for 8 to 10 minutes. Remove the pan and let the pistachios cool completely before breaking them apart and chopping them.
• Melt the chocolate chips in a doubler boiler or in the microwave. Once they are melted, stir in the coconut oil until it’s melted. Remove the cake from the pan once it has cooled slightly and pour the chocolate overtop. Cover the chocolate with the chopped pistachios. Slice and serve!
