Prep & Cook Time
- Prep Time: 20 minutes
- Cook Time: 25 minutes
- Total Time: 45 minutes
- Servings: 12 muffins
Ingredients
- 2 1/4 cups all-purpose flour
- 2 teaspoons pumpkin pie spice
- 1 teaspoon baking soda
- 1/2 teaspoon kosher salt
- 1 egg
- 1 cup buttermilk
- 1/2 cup butter (melted)
- 1 teaspoon pure vanilla powder (use half this amount if you prefer less rich vanilla flavor)
- 1 1/2 cups packed brown sugar
- 2 cups peeled and chopped Granny Smith Apples
- 1/2 cup packed brown sugar
- 1/3 cup all-purpose flour
- ¼ cup rolled oats
- 1 teaspoon ground cinnamon
- 3 tablespoons butter (melted)
Instructions
- Preheat your oven to 375°F (190°C). Grease a 12-cup muffin tin or line it with paper liners.
- In a large bowl, whisk together the 2 1/4 cups all-purpose flour, pumpkin pie spice, baking soda, and kosher salt.
- In a separate medium bowl, whisk the egg. Then add the buttermilk, 1/2 cup melted butter, vanilla powder (use half this amount if you prefer less rich vanilla flavor), and 1 1/2 cups packed brown sugar. Whisk until smooth.
- Fold in the peeled and chopped Granny Smith apples.
- Divide the batter evenly among the 12 prepared muffin cups.
- Make the streusel topping: In a small bowl, combine the 1/2 cup packed brown sugar, 1/3 cup all-purpose flour, rolled oats, and ground cinnamon. Stir in the 3 tablespoons melted butter until the mixture is crumbly.
- Sprinkle the streusel topping evenly over the muffin batter.
- Bake for 20-25 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
- Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
Variations
- Mini Muffins: Use a mini muffin tin and reduce baking time to 12-15 minutes for bite-sized treats.
- Loaf Form: Pour the batter into a greased 9×5-inch loaf pan, top with streusel, and bake for 50-60 minutes.
- Extra Crispy Top: Broil the cooled muffins for 1-2 minutes to re-crisp the streusel topping before serving.
- Glaze Option: After baking, drizzle the muffins with a simple glaze made from whisking buttermilk and powdered sugar.
Tips for Success
- Chop the apples into small, uniform pieces (about 1/2-inch) so they distribute evenly and bake properly.
- For the best crumbly streusel, make sure your butter for the topping is just melted, not hot.
- Fill any empty muffin cups in your tin with a little water to prevent warping and ensure even baking.
Storage & Reheating
Store leftover muffins in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days. To reheat, warm them in a 300°F oven for 5-10 minutes or in the microwave for 15-20 seconds to restore their moisture and crisp the topping.
FAQ
Can I use regular milk instead of buttermilk?
No, buttermilk is crucial for the right acidity and moisture. If you must substitute, make a soured milk by adding 1 tablespoon of lemon juice or vinegar to 1 cup of regular milk and let it sit for 5 minutes.
Why is kosher salt specified?
Kosher salt has a different density and flavor distribution than table salt. If you use table salt, reduce the amount by half to avoid over-salting.
My streusel sunk into the batter. Why?
This happens if the batter is too liquid or the streusel is too wet. Ensure your streusel is crumbly and your muffin batter is thick and well combined before adding the topping.
Can I prepare the batter ahead of time?
It’s best to bake immediately. The baking soda begins reacting once mixed with the buttermilk, and waiting will result in less rise.
What if I don’t have pumpkin pie spice?
You can make a substitute using the spices from the streusel. For every 1 teaspoon of pumpkin pie spice, use 1/2 tsp cinnamon, 1/4 tsp ginger, 1/8 tsp nutmeg, and 1/8 tsp allspice.
How do I know when the muffins are done?
The tops should be golden, and a toothpick inserted into the center (avoiding a large apple piece) should come out with just a few moist crumbs, not wet batter.
