01 - Combine rolled oats, almond milk, ripe banana, Greek yogurt, maple syrup, vanilla extract, ground cinnamon, and salt in a blender. Process until completely smooth and creamy, approximately 1-2 minutes.
02 - Transfer blended mixture to a small saucepan. Cook over medium heat, stirring frequently to prevent sticking, for 3-5 minutes until thickened and heated through.
03 - While oats cook, whisk together almond butter, maple syrup, and ground cinnamon in a small bowl until smooth and well combined.
04 - Pour hot oats into serving bowls. Spoon cinnamon swirl mixture on top and gently swirl with a knife or spoon to create marble pattern.
05 - Top with chopped nuts, raisins, additional yogurt, and extra maple syrup drizzle as desired. Serve immediately while warm.
