We're taking the classic Rocky Road ice cream to another level- rocky road brownies! Layers of fudgy brownie, gooey marshmallows, and almond ganache- they're made in one bowl with no mixer in less than one hour!
Preheat the oven to 350F/180 C. Prepare an 8x8 square baking pan with parchment paper to cover all four sides.
In a microwave-safe bowl, melt the butter and chocolate chips, stirring every 20-30 seconds, until smooth. Whisk in the cocoa powder, then set aside.
In a large bowl, whisk together the brown sugar, granulated sugar, eggs, egg yolk, and vanilla.
Stream the melted chocolate mixture into the mixing bowl and whisk until combined. Then, fold in the flour, salt, and chocolate chips.
Pour the brownie batter into the prepared baking pan. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out covered in a few moist crumbs. Spread the mini marshmallows on top and return the pan to the oven for 3 minutes.
Then let the pan cool on a wire rack while you make the almond ganache.
Heat the cream until almost boiling, then pour it over the chocolate chips. Wait 1 minute, then stir to combine. Once smooth, stir in the chopped almonds. Allow to cool for 3 minutes, then gently spread it over the top of the marshmallows. Let the brownies finish cooling at room temperature, then chill in the fridge for 1 hour before cutting to make them easier to slice.

Notes
*Measure your flour properly. This is my #1 baking tip! Do not ever scoop a measuring cup into your flour, as this always leads to using too much flour. Instead, use the spoon-level method. This means fluffing the flour first, then spooning it into your measuring cup/spoon. For the BEST results, use a kitchen scale!*Use a light-colored metal pan. Glass, ceramic, and dark-colored pans retain heat differently and will bake differently.Cut with a sharp knife. Use a sharp knife, wiping it clean between cuts, for clean slices!Storage: Store leftover brownies in an airtight container at room temperature for 2-3 days. You can also freeze them for up to 1 month in an airtight container or freezer bag.Substitutions: Feel free to substitute the nuts for your favorite or leave them out completely.
