Ingredients You’ll Need
To make these Cinnamon Apple Oatmeal Muffins, you’ll start with 3 cups of homemade oatmeal muffin mix as the base. Add 1 teaspoon of cinnamon for that signature warmth, plus ½ cup of milk to create a moist batter. You can use one egg or replace it with ¼ cup of applesauce for a dairy-free or vegan option. The key ingredient is 1½ cups of peeled and diced Granny Smith apples, which add a sweet-tart bite and help keep the muffins moist. For extra flair, sprinkle diced apples and a few oats on top before baking for that bakery-style finish.
Step-by-Step Instructions
Preheat and Prepare
Start by preheating your oven to 350°F (175°C). Line a standard muffin tin with paper liners to make cleanup easier.
Mix the Batter
In a large bowl, combine the oatmeal muffin mix, cinnamon, milk, egg (or applesauce), and diced apples. Stir until just mixed — overmixing can make your muffins dense instead of fluffy.
Fill and Bake
Using a large cookie scoop, fill each muffin cup evenly with the batter. This ensures uniform size and even baking. Bake for 20–25 minutes, or until a toothpick inserted in the center comes out clean.
Cool and Enjoy
Let the muffins cool in the pan for a few minutes before transferring them to a rack. They’re delicious warm from the oven or at room temperature. Pair them with your morning coffee or tea for a comforting start to your day.
Tips for Perfect Muffins Every Time
Don’t overmix your batter — that’s the secret to light and tender muffins. Always scoop the batter evenly so each muffin bakes at the same rate. Check doneness by inserting a toothpick; it should come out clean. For extra flavor, top the muffins with a sprinkle of oats or cinnamon sugar before baking. If you love apple flavor, mix in a few more diced pieces right before baking for a juicy texture in every bite.
Variations and Substitutions
These muffins are flexible and fun to customize. Try adding chopped walnuts or pecans for crunch, or a handful of raisins for sweetness. A dash of nutmeg or ginger deepens the flavor beautifully. You can swap the egg for applesauce or a flax egg for a vegan-friendly option. To make them slightly sweeter, drizzle a little honey or maple syrup on top once they’ve cooled.
How to Store and Reheat
Store your muffins in an airtight container at room temperature for up to 3 days or refrigerate them for up to a week. For longer storage, freeze in a sealed bag for up to 3 months. Reheat in the microwave for 10–15 seconds or warm in the oven for a few minutes to bring back that fresh-baked taste. They’re perfect for meal prep or easy weekday breakfasts.
