Ingredients

• ¾ cup Old Fashioned rolled oats (or up to 1 cup)
• 1 tablespoon peanut butter
• ½ cup Greek yogurt
• ½ cup milk (or omit yogurt and use ¾ cup oat milk for vegan)
• 1 1/2 ripe bananas (room temperature)
• 1 cup frozen pineapple
• 1/4 to 1/2 teaspoon cinnamon
• 8 ice cubes
• Maple syrup, to taste (optional)

Instructions

1. Add the ingredients to a blender, breaking the banana into pieces. Blend until creamy and frothy, stopping and scraping down the sides as necessary. 
2. Taste: depending on the ripeness of the bananas, you may want to add a drizzle of maple syrup. Eat immediately or store 1 day in a sealed jar; if it separates, shake to re-integrate it.
