1/2 cup almond or macadamia nut butter  
1 1/2 cups mashed bananas (4-5 bananas) + 1 extra banana, sliced  
3 cups old-fashioned oats  
1 1/2 cups plain unsweetened almond milk (or coconut, soy, your choice)  
1/4 cup maple syrup or honey  
1 tsp vanilla extract  
1/2 tsp kosher salt  
1 cup chopped macadamia nuts 

How to make it:  
Preheat oven to 375 and position a rack in the center. Thoroughly grease a muffin tin with coconut oil.  
Combine all ingredients in a large bowl and stir until combined. Spoon into muffin cups. Top with a few chopped mac nuts and a slice of banana.  
Place tin in the oven and bake until oatmeal cups are firm to the touch, about 20-25 minutes (it might take a little bit longer, depending on your oven)  
Wait a couple of minutes for oatmeal cups to cool before running a knife around the edges and removing them from the tin. Enjoy!
