In a large mixing bowl, cream together the butter, coconut oil, brown sugar, and coconut sugar until very creamy (about 90 seconds). Add in the egg, honey, and vanilla. Beat until well combined.
In a seperate bowl, combine the dry ingredients (flour, baking soda, cinnamon, and cloves). Stir until combined.
Add the oats to the dry mixture and stir to combine.
Using a standing or handheld mixer, mix the dry ingredients into the wet ingredients.
On a parchment paper lined baking sheet, scoop 2 tbsp. of the dough out at a time. Space the cookies at least 2 inches apart.
Bake at 375 for 11 minutes. Feel free to play with the time a little bit if you like a crispier or softer cookie!
Meanwhile, prepare the creme filling. Beat the butter until creamy, about 30 seconds. Add the sugar and beat for one minute. Add the milk and vanilla and beat for 2 more minutes, or until very creamy.
Once the cookies have cooled, pair the cookies up with ones of equal size. Spread the creme filling on the inside of one of the cookies in the pair and top with the other cookie. Enjoy!
