Chewy brownies meet warm, spicy gingerbread.
Grease an 8"x8" or 9"x9" pan. Set aside.
Preheat oven to 350 degrees.
Melt butter and chocolate in a heat-proof bowl over a pan filled with about 1" of simmering water.
Turn heat off to pan. Add the molasses and both sugars to the bowl of melted chocolate. Whisk well until sugar granules are melted.
Remove bowl from sitting over the hot pan and whisk in the eggs. Thoroughly mix.
Add remaining ingredients and whisk only to combine. Do not overmix.
Add mixture to prepared pan.
Bake for 25-30 minutes, removing when your toothpick comes out with a few crumbs attached to it. Test with your toothpick in the center of your brownies.
