Preheat oven to 350F, grease your donut pan and set aside.

Meanwhile, combine dry ingredients in mixing bowl until fully combined. Then add in wet ingredients one at a time, mixing in between. Once all ingredients are combined, slowly pour into donut pan filling each mold to the top.

Bake for ten minutes. While you wait you can prepare your toppings. Either make your frosting, or use a premade spread like I did. For the graham crackers, break these apart so you can crumble on top of the donuts later. If you're using mini marshmallows, set aside a handful--otherwise, tear your full sized marshmallows into smaller pieces.

Once donuts are done, let cool for five minutes in the pan. Then take out and let cool on cooling rack for ten more minutes. Frost donuts and sprinkle on your toppings.
