Preheat oven to 425 F and grease a square 8 x 8-inch baking dish. In a large bowl, mix dry ingredients. In a medium bowl, melt the 6 tablespoons of butter, then whisk in buttermilk and eggs. Pour wet mixture into dry mixture and mix until well incorporated. Pour into greased dish and bake 25 minutes.
Meanwhile, in a small bowl, mix together softened butter, honey, and hot sauce until smooth. Taste for spice level and add more hot sauce if desired, then serve with cornbread. Butter can be kept at room temperature in a covered container for 2 days and added to other dishes like roasted carrots, fried chicken, or grilled corn on the cob.
