Preheat your oven to 375°F (190°C) and line a muffin tin with paper liners.

In a large mixing bowl, combine rolled oats, all-purpose flour, brown sugar, baking powder, baking soda, cinnamon, and salt.

In another bowl, whisk together applesauce, milk, vegetable oil, and egg until well combined.

Pour the wet ingredients into the dry ingredients and stir until just combined.

Fold in chopped nuts and chopped apples.

Divide the muffin batter evenly among the prepared muffin cups, filling each about 2/3 full.

Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean.

Brew the coffee and refrigerate to cool.

Remove from the oven and let the muffins cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.

Pour coffee over ice. Prepare to your liking.

Drizzle the honey glaze over the muffins.

Serve with iced coffee.
