Mix butter and honey together just until combined – do not cream it or over beat it. Add milk, gently mix until combined and smooth
In a separate bowl, whisk together remaining ingredients. Add dry mix to butter and honey, mix until combined. Wrap dough in plastic film, chill for 1 hour.
Preheat the oven to 350 degrees F, line baking sheets with parchment paper.
Generously sprinkle clean work surface with corn starch, roll dough to ½″ thick. Cut into 3″ squares, and carefully transfer biscuits to prepared baking sheets, leaving 2″ between each. Cut a shallow “X” into each cake, if desired.
Bake for about 15 minutes, or until lightly golden. Allow cakes (biscuits?) to cool on cookie sheets for at least 5 minutes before moving, cool completely before serving.
If you want to get fancy with it, wrap them in leaves, and tie with twine. (I used collard greens).
