01 - Preheat oven to 350°F. Line a standard 12-cup muffin tin with paper liners or grease thoroughly with nonstick spray.
02 - In a large bowl, whisk together oats, baking powder, cinnamon, and salt until evenly distributed.
03 - In a separate bowl, whisk applesauce, milk, eggs, honey or maple syrup, melted coconut oil or butter, and vanilla extract until fully blended and smooth.
04 - Pour wet ingredients into dry ingredients and stir until completely incorporated, ensuring no dry patches remain.
05 - Gently fold in any optional add-ins such as berries, nuts, or chocolate chips, being careful not to overmix.
06 - Divide the oatmeal mixture evenly among the prepared muffin cups, filling each approximately 3/4 full.
07 - Bake for 22–25 minutes until cups are set and lightly golden on top. Remove from oven and let cool in pan for 10 minutes before transferring to a wire rack to cool completely.
08 - In a small bowl, mix Greek yogurt with honey or maple syrup until smooth and evenly sweetened.
09 - Once oatmeal cups have cooled completely, top each with a generous spoonful of sweetened Greek yogurt and garnish with fresh berries or fruit.
