How to Make Apple Oatmeal Crumble Muffins Recipe

Step 1: Prepare the Streusel Topping

Start by combining half a cup each of all purpose flour and rolled oats with a quarter cup of brown sugar, half a teaspoon of apple pie spice, and an eighth of a teaspoon of salt in a small bowl. Cut in a quarter cup of cold, unsalted butter using a pastry blender or fork until the mixture resembles coarse crumbs. Set this irresistible crumble aside for later—it’s going to add that perfect crunchy topping.

Step 2: Preheat Oven and Prepare Muffin Pan

Heat your oven to 350 degrees Fahrenheit (177 degrees Celsius). Give your muffin pan a quick spray with baking spray to ensure each muffin comes out cleanly and easily.

Step 3: Mix the Dry Ingredients for Muffins

In a large bowl, whisk together one and a quarter cups each of all purpose flour and rolled oats, half a cup of granulated sugar, a quarter cup of brown sugar, one and a half teaspoons of baking powder, half a teaspoon of baking soda, a third of a teaspoon of salt, and one and a third teaspoons of apple pie spice. This dry base will create the fluffy structure and wonderful flavor foundation of the muffins.

Step 4: Combine Wet Ingredients

In a smaller bowl, whisk two large eggs with half a cup of buttermilk, a third cup of vegetable oil, and one and a quarter teaspoons of vanilla bean paste. These wet ingredients add moisture, richness, and a gentle tang that contrasts beautifully with the sweetness and spice.

Step 5: Mix Wet and Dry Ingredients

Pour the wet mixture into the bowl of dry ingredients and stir just until they come together. Be careful to avoid over-mixing so the muffins stay tender and light.

Step 6: Fold in Chopped Apples

Gently fold in two cups of chopped Granny Smith apples. Their tartness and crisp texture elevate these muffins and make every bite exciting.

Step 7: Fill Muffin Cups and Add Streusel

Using a three-tablespoon scoop, portion the batter evenly into the prepared muffin pan. Top each mound of batter with a generous sprinkle of the oat crumble streusel you made earlier. This topping will bake up to a golden, crisp layer full of flavor and texture.

Step 8: Bake Until Golden

Bake the muffins in the preheated oven for 20 to 25 minutes, or until a toothpick inserted into the center comes out clean. The aroma wafting through your kitchen at this point is pure magic!

Make Ahead and Storage

Storing Leftovers

Once cooled, store the Apple Oatmeal Crumble Muffins in an airtight container at room temperature for up to two days. This keeps them moist and fresh without losing the crispness of the topping.

Freezing

If you want to keep these muffins on hand for longer, freeze them individually wrapped in plastic wrap and then placed in a freezer bag. They will keep beautifully for up to three months. Just thaw at room temperature when ready to enjoy.

Reheating

To enjoy a muffin that tastes as fresh as when you baked it, warm it in a microwave for about 20 seconds or pop it into a preheated oven at 325 degrees Fahrenheit for 5 to 7 minutes. The crumble topping will regain its lovely crispness.
