Preheat oven to 400° F. Line your 8x8” brownie pan with parchment paper.
In a large bowl, whisk together the first 5 ingredients.
In a medium bowl, whisk together the butter, sugar and honey until smooth. Add in the egg and whisk until combined. Lastly whisk in the buttermilk.
Add the wet to the dry and mix until just combined. Do not over mix. Transfer batter to pan and bake for 20-22 minutes or until toothpick comes out clean. Allow to cool at least 10 minutes prior to slicing.
Notes
If you don't have buttermilk, you can sub in 3/4 cup sour cream (or Greek yogurt) and 1/4 cup milk (or water) mixture.
