Slather a light layer of pistachio butter (or nut butter of your choice) onto all six pancakes. Warm in the microwave for 30 seconds, if pancakes are frozen.
Top three pancakes with strawberry slices. Add remaining pancakes on top, pistachio-butter-coated-side-up (so it looks like a green monster head).
Break each mini marshmallow in half and smoosh it with your fingers to flatten it. Stick a mini chocolate chip onto the cut-open part of the marshmallow (it'll be sticky and help the chocolate chip adhere to it). Stick the "eyes" on each monster.
Add remaining chocolate chips as "hair" along the top of each monster, if desired. Serve as-is or with a drizzle of maple syrup.
