In a large mixing bowl, whisk together the flour, graham cracker crumbs, baking powder, baking soda, and salt.
In a separate mixing bowl, whisk together the egg, milk, oil, vanilla, and brown sugar. Add dry mixture to wet mixture and stir gently until combined.
Heat non-stick pan or griddle over medium-high heat.
Once hot, spray with non-stick cooking spray and drop pancakes onto hot pan using a ⅛ measuring cup. Spread out into a 4-inch circle.
Cook on the first side until batter begins to bubble, then flip and cook the other side an additional 2 to 3 minutes, or until lightly browned.
Place pancakes on a baking sheet and top each with a few mini chocolate chips, a few mini marshmallows, and a dash of salt.
Broil for 1 minute, or until marshmallows are toasted.
Sprinkle with a tiny pinch of salt, if desired, then fold up and serve.
Any type of milk would work fine here, even milk alternatives such as soy or almond milk.
