Preheat oven to 350°F and lightly grease a donut pan.
Prepare pancake batter according to package directions using water or plant-based milk, then mix in the marshmallow syrup.
Spoon or pipe batter into donut pan, filling about 3/4 full.
Sprinkle chocolate chips and crushed graham crackers on top and lightly press them into the batter.
Bake for 10–14 minutes, or until set and lightly golden.
Let cool slightly before removing from pan and serving.
