Preheat and Prep:Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners or lightly grease the tin to prevent sticking.
Mix the Dry Ingredients:In a large bowl, combine the rolled oats, chopped pecans, baking powder, cinnamon, and salt. Give everything a quick stir to evenly distribute the dry ingredients.
Whisk the Wet Ingredients:In a separate bowl, whisk together the milk, eggs, maple syrup, vanilla extract, and melted coconut oil. Make sure the coconut oil is cooled slightly to prevent cooking the eggs!
Combine Wet and Dry:Pour the wet ingredients into the bowl of dry ingredients, stirring until everything is well combined. Let the mixture sit for about 5 minutes, allowing the oats to soak up some liquid for a fluffier texture.
Fill the Muffin Cups: Spoon the mixture evenly into the muffin tin, filling each cup almost to the top. Sprinkle extra chopped pecans on top for added crunch.
Bake: Bake in the preheated oven for 25–30 minutes, or until the oatmeal cups are golden brown and firm to the touch. A toothpick inserted into the center should come out clean.
Cool and Serve: Let the oatmeal cups cool in the tin for about 10 minutes before transferring them to a wire rack to cool completely.
