Preheat oven to 350 degrees.
Add pumpkin puree, brown sugar, white sugar, coconut oil, and vanilla to the mixing bowl. Beat together, add eggs. Mix until fully combined.
In a separate bowl, add the flour, baking powder, baking soda, cinnamon, salt, and all spice. Stir to combine.
Slowly add the dry mixture to the wet, while beating at low speed. Beat just until you can't see flour anymore. Be careful not to over mix.
Scoop the mixture into a pastry bag or ziplock bag, cut the tip off. Pipe circles onto a lined tray. Bake for 10 minutes and cool the cookies on a wire rack. Repeat piping instructions for the second tray, add M&M's® Pecan Pie to each cookie top.
Scoop Pillsbury™ Creamy Supreme® icing into a ziplock bag, cut the tip off and fill each cookie bottom. Find a top that is similar in size and shape, press lightly together.
