Preheat oven to 350° F. Line an 8" x 8" baking dish with parchment paper.
Add ½ cup of the chocolate chips or chunks to a microwave safe bowl. Microwave for one minute, then stir. Microwave in 15 second intervals and remove to stir until chocolate has melted. Set aside to cool a bit.
Add the melted butter and the maple sugar to a large bowl. Beat with an electric hand mixer until fluffy. Add in the eggs, vanilla extract, and peppermint extract and beat 1-2 minutes more. Add in the melted chocolate and use a spoon to combine.
Add in all of the dry ingredients and stir with the spoon until just combined. Do not over mix. Fold in the remaining ½ cup of chocolate chips or chunks. Transfer the batter to the parchment paper lined baking dish. Bake at 350° F for 35-40 minutes, until a toothpick inserted in the brownies comes out clean. You may have to try a few different places to make sure you are getting all brownies and no melted chocolate pieces!
Let cool almost completely. Slice and enjoy!
