These apple cinnamon oat muffins with espresso glaze are hearty, simple to make, and healthy enough to feel good about eating a few. Loaded with oats and apples for a perfect breakfast or snack!
Preheat the oven to 375 F. Line a 12-cup muffin tin with paper liners.
Pour oats and buttermilk in a large bowl, allow to sit and absorb for 10 minutes if you have the time.
Add the oil, brown sugar, eggs and vanilla. Mix until combined.
Stir in the baking powder, baking soda, salt, cinnamon, nutmeg and flour until just combined. Fold in the diced apples.
Divide the batter into the prepared muffin cups, I like to fill mine very full so they raise larger. Let them sit while you prepare the oat crumble.
Mix together the oats, flour, brown sugar and cinnamon. Add melted butter and mix until like wet sand. Sprinkle on top of muffin batter.
Bake for 17-20 minutes, or until a light golden brown rim has formed along the edges. Allow to cool.
Mix together espresso powder and warm water. Add in powdered sugar and milk and whisk. Drizzle over cooled muffins.
