Step-by-Step Instructions

Making these muffins is quick and simple:

Preheat the Oven
Heat your oven to 375°F (190°C). Line a muffin tin with paper liners or grease lightly.

Mix the Dry Ingredients
In a large bowl, combine oats, flour, baking powder, baking soda, cinnamon, nutmeg, and a pinch of salt.

Mix the Wet Ingredients
In another bowl, whisk together eggs, milk, brown sugar (or honey), yogurt (or applesauce), vanilla, and melted butter.

Combine and Fold in Apples
Add the wet ingredients to the dry mixture. Stir gently until just combined. Fold in the diced apples.

Fill the Muffin Cups
Spoon the batter evenly into the muffin tin, filling each about ¾ full.

Bake the Muffins
Bake for 18–22 minutes, or until a toothpick inserted in the center comes out clean.

Cool and Enjoy
Let muffins cool slightly before serving. Enjoy warm or store for later.
