Apple Cinnamon Crumb Muffins

These Apple Cinnamon Crumb Muffins are soft and fluffy with a delicious streusel topping. A finely chopped pink lady or honeycrisp apple is added to the batter for a hint of apple in every bite. They're easy to make and can be ready in about 30 minutes.

The crumb topping is made of a few basic ingredients and comes together quickly. It chills in the fridge while you whip up the muffin batter and is then added on top before being baked.

A FEW NOTES BEFORE WE GET STARTED

• Room Temperature Ingredients:
  • Butter: It’s important that your butter is softened. In a pinch, you can put your butter in the microwave for about 5 seconds on each side, but watch closely to make sure it is just softening and not melting.
  • Eggs: You also want to make sure that the eggs are at room temperature to ensure that they are properly incorporated into your batter. If you forget to leave them out before you start baking, place them in a bowl of warm water for about 15 minutes until they become room temperature.
• Measuring Your Ingredients: I strongly encourage that you use a kitchen scale to measure your ingredients and ensure that you have the most accurate measurements possible.
  • However, if you don’t have a scale on hand and will be using cup measurements, make sure to use the “spoon and sweep” method when measuring to avoid packing in too much of any dry ingredient.
• Oven Temperature: Make sure to preheat your oven for at least 15 minutes before you start baking.
  • I recommend purchasing an oven thermometer to get to know your oven so you can adjust your baking temperatures accordingly. Some ovens run slightly warmer or colder so its important to know yours to make sure your baked goods come out right.

Combine the sugars, flour, cinnamon, salt, and butter for the topping in a small bowl. Mix together with your hands, gently massaging the dry ingredients into the butter. Continue to mix until the butter is in pea sized pieces or slightly larger. Chill until ready to use.

Preheat oven to 400º F. In a large bowl, whisk together the flour, baking powder, salt, and cinnamon and set aside. In a stand mixer fitted with a paddle attachment or with a handheld mixer mix the sugars and butter together on medium speed until light and fluffy.

Add the eggs, one at a time, with the mixer on medium speed, and scrape down the sides of the bowl as needed.

Add the sour cream and mix just until combined. Scrape down the sides of the bowl.

Add the flour mixture and apple and mix just until combined. Scoop the batter into 12 muffin liners, so that each liner is about ¾ full.

Sprinkle the streusel evenly on top of each muffin so that all of the batter is covered.

Bake muffins for 5 minutes. Turn oven down to 350º F and continue to bake for another 14-15 minutes until golden brown.

Let muffins cool slightly on a cooling rack. Enjoy!
