Preheat the oven to 350 degrees F and grease or line six muffin tins.
Mash the banana, the pumpkin, and the almond butter together in a large mixing bowl. Add the dried cranberries, milk, maple syrup, and salt. Stir to thoroughly combine. Stir in the oats and mix to incorporate.
Distribute the mixture among the prepared muffin tins. (I like to use a large ice cream scoop for an even and mess-free transfer.)
Bake for 20 minutes or until the muffins are firm on the top and just cooked through the center.
Cool in the pan for 5 minutes and then remove. Enjoy right away or allow to cool completely. Cover and store any leftovers muffins in the refrigerator.
