Preheat the oven to 350°F and line an 8x8-inch baking pan with parchment paper.
Add the melted butter, light brown sugar, and sifted cocoa powder to a large mixing bowl and, using a hand mixer, beat until smooth. Add the eggs, oil, honey, salt and vanilla extract, and mix until everything is fully incorporated.
¾ cup Unsweetened cocoa powder, ½ cup Unsalted Butter,, 1 cup Light brown sugar, 1 tbsp Honey, 2 Eggs, 4 tbsp Olive oil, ¼ tsp Salt, 1 tsp Vanilla extract
Add gluten-free blend and mix until combined using silicone spatula.
¾ cup Gluten-Free Flour Blend
Pour the batter into the prepared pan, smooth it with a spatula and bake for 30 minutes. Let it completely cool before making the ganache.
Ganache
Place the chopped chocolate in a medium bowl. In a separate microwave-safe bowl, heat the heavy cream in the microwave for 1-2 minutes, or until it comes to a simmer. Pour the hot cream over the chocolate and let it sit for 1 minute to soften the chocolate. Microwave the mixture for 15 seconds at a time, stirring after each interval until the chocolate has melted and the mixture is smooth. Be sure not to overheat.
8 oz Dark chocolate, ½ cup Heavy cream
Spread the ganache evenly over the cooled brownies, and then sprinkle with chocolate chips and chopped nuts. Place the brownies in the fridge for a few hours. Once the ganache is set, cut the brownies and serve.
Make sure to line the baking pan with parchment paper, this will distribute the heat more evenly during baking, and help them to come out of the pan after baking.
