Flourless Rocky Road Brownies

Preheat the oven to 350°F and grease an 8×8 baking pan. In a glass bowl, microwave 1 cup chocolate chips with butter or coconut oil, stirring every 30 seconds until melted. Let cool slightly.

In the bowl of a standing mixer with the whisk attachment, combine eggs and sugar on medium-high speed until combined. Add melted chocolate, and mix on medium speed until combined.

On low speed, mix in cocoa powder, tapioca starch and salt. Pour brownie batter into greased pan, and bake at 350°F until a tester comes out with a few dry crumbs, about 35–40 minutes.

Remove brownies from the oven, and top with remaining 1 cup chocolate chips, mini marshmallows and chopped nuts. Return brownies to the oven and bake for an additional 5 minutes, until marshmallows start to melt. Remove from the oven and cool completely before serving.
