Prep & Cook Time

Prep Time: 10 minutes

Cook Time: 25 minutes

Total Time: 35 minutes

Servings: 12 muffins

Ingredients

• ¾ cup all-purpose flour
• ½ cup light brown sugar
• 1 teaspoon cinnamon
• ½ teaspoon salt
• 5 tablespoons unsalted butter (cut into small pieces)
• 2 large eggs
• 1 cup white sugar
• ½ cup vegetable or canola oil
• 1 teaspoon vanilla powder (use half this amount if you prefer less rich vanilla flavor)
• 2 cups all-purpose flour
• 1 teaspoon cinnamon
• ¼ teaspoon nutmeg
• ½ teaspoon salt
• ½ teaspoon baking soda
• 1 cup sour cream (light or regular) (can substitute plain Greek yogurt (nonfat or whole fat))
• 1 medium crisp-sweet apple ((like Envy, Honeycrisp, Mutsu, Fuji, or Gala) peeled, cored, and chopped (1 heaping cup))
• ½ cup powdered sugar
• 4 to 5 teaspoons heavy cream or half-and-half (or as needed to reach desired consistency)
• ½ teaspoon vanilla

Instructions

1. Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease well.
2. Make the streusel topping: In a small bowl, combine ¾ cup flour, ½ cup brown sugar, 1 teaspoon cinnamon, and ½ teaspoon salt. Add the 5 tablespoons of cold, cubed butter. Use a pastry cutter, fork, or your fingers to work the butter into the dry ingredients until the mixture resembles coarse crumbs. Set aside.
3. Make the muffin batter: In a large bowl, whisk together the 2 eggs, 1 cup white sugar, ½ cup oil, and 1 teaspoon vanilla powder (use half this amount if you prefer less rich vanilla flavor) until smooth and well combined.
4. In a separate medium bowl, whisk together the 2 cups flour, 1 teaspoon cinnamon, ¼ teaspoon nutmeg, ½ teaspoon salt, and ½ teaspoon baking soda.
5. Divide the batter evenly among the 12 prepared muffin cups, filling each about ¾ full. Generously sprinkle the prepared streusel topping over each muffin, pressing it down lightly so it adheres.
6. Bake for 22-25 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.
7. Make the glaze: While the muffins cool, whisk together the ½ cup powdered sugar, ½ teaspoon vanilla, and 4 teaspoons of heavy cream. Add more cream, ½ teaspoon at a time, until you reach a thick but pourable consistency. Drizzle the glaze over the cooled muffins.

Variations

• Mini Muffins: Bake in a mini muffin tin for about 12-15 minutes for a bite-sized treat.
• Bundt or Loaf: Pour the batter into a greased 9×5-inch loaf pan or small bundt pan. Increase baking time to 50-60 minutes, checking for doneness with a toothpick.
• Streusel Swirl: Reserve half of the streusel and gently swirl it into the muffin batter in the cups before adding the top layer of streusel for a marbled effect.
• Serve Warm with a Dip: Serve the warm, unglazed muffins with a side of extra sour cream or Greek yogurt for dipping.

Tips for Success

• Use cold butter for the streusel to ensure it stays crumbly and doesn’t melt into the batter before baking.
• For even baking and picture-perfect tops, use a cookie scoop or measuring cup to portion the batter into the muffin cups.
• Ensure your muffins are completely cool before drizzling the glaze, otherwise it will melt and soak in.

Storage & Reheating

Store cooled, glazed muffins in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. To reheat, warm individual muffins in the microwave for 10-15 seconds to restore their soft texture.

FAQ

Can I use a different type of apple?

Yes, any crisp-sweet apple variety listed (like Gala or Honeycrisp) works well. Avoid very soft apples like Red Delicious, as they can become mushy.

Can I make these muffins ahead of time?

Absolutely. You can prepare the streusel topping and store it in the fridge overnight. The batter can also be mixed, covered, and refrigerated for up to 12 hours before baking—just give it a gentle stir before portioning.

My glaze is too thin/thick. How do I fix it?

If too thin, add more powdered sugar, a tablespoon at a time. If too thick, add more cream, ½ teaspoon at a time, until it reaches a drizzle-able consistency.

Can I use melted butter instead of oil?

While oil keeps the muffins exceptionally moist, you can substitute an equal amount of melted, cooled butter for a richer flavor.

Why did my streusel sink into the batter?

This usually happens if the butter in the streusel was too soft or melted. Ensure your butter is cold, and press the streusel lightly onto the batter to help it stay on top.

Can I freeze these muffins?

Yes, freeze unglazed muffins in a single layer on a baking sheet, then transfer to a freezer bag for up to 3 months. Thaw at room temperature and add the glaze before serving.
