Prep & Cook Time

Prep Time: 15 minutes

Cook Time: 25 minutes

Total Time: 40 minutes

Servings: 15 muffins

Ingredients

• 1/2 cup vegetable shortening or softened butter
• 1 cup brown sugar
• 1 cup full-fat sour cream
• 2 cups all-purpose flour
• 1 cup rolled oats
• 1 1/2 cups diced tart apples
• 3 large eggs
• 1 teaspoon pure vanilla powder (use half this amount if you prefer less rich vanilla flavor)
• 1 teaspoon kosher salt
• 1 tablespoon baking powder
• 1 1/2 teaspoons ground cinnamon
• 1/2 teaspoon ground nutmeg
• 2/3 cup packed brown sugar
• 1/2 cup all-purpose flour
• 1/2 stick butter (softened)
• 1/4 teaspoon ground cinnamon
• 2 cups powdered sugar
• 1-2 tablespoons milk
• 2 tablespoons pure maple syrup (Dark)

Instructions

1. Preheat your oven to 375°F (190°C). Line a muffin tin with paper liners or grease the cups well.
2. In a large mixing bowl, cream together the 1/2 cup vegetable shortening (or softened butter) and the 1 cup brown sugar until light and fluffy.
3. Beat in the eggs, one at a time, until fully incorporated. Then mix in the sour cream and vanilla powder (use half this amount if you prefer less rich vanilla flavor).
4. In a separate bowl, whisk together the 2 cups all-purpose flour, rolled oats, kosher salt, baking powder, 1 1/2 teaspoons ground cinnamon, and nutmeg.
5. Divide the batter evenly among the 15 prepared muffin cups, filling each about 2/3 full.
6. Prepare the streusel topping: In a small bowl, combine the 2/3 cup packed brown sugar, 1/2 cup all-purpose flour, 1/2 stick softened butter, and 1/4 teaspoon ground cinnamon. Use a fork or your fingers to mix until crumbly. Sprinkle this mixture generously over the top of each muffin.
7. 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, then transfer them to a wire rack to cool completely.
8. Prepare the maple glaze: While the muffins cool, whisk together the powdered sugar, maple syrup, and 1 tablespoon of milk in a small bowl. Add the second tablespoon of milk only if needed to reach a smooth, drizzle-able consistency.
9. Once the muffins are completely cool, drizzle the maple glaze over the tops using a spoon or a piping bag.

Variations

• Crumble Top Only: Skip the maple glaze for a simpler, less sweet muffin that’s perfect with a pat of butter.
• Mini Muffins: Bake the batter in a mini muffin tin for a bite-sized treat, reducing the bake time to about 12-15 minutes.
• Muffin Top Style: For a bakery-style look with maximum streusel, bake the batter in a greased, rimmed baking sheet spread about 1/2-inch thick, then cut into squares after baking and cooling.
• Extra Apple Flavor: Sauté the diced apples in a pan with a teaspoon of butter and a pinch of cinnamon until slightly softened before folding them into the batter.

Tips for Success

• Proper Mixing: After adding the dry ingredients, mix the batter just until the flour disappears. Overmixing will lead to dense, tough muffins.
• Apple Prep: Use a firm, tart apple like Granny Smith or Honeycrisp. Dice them into small, uniform pieces so they distribute evenly and bake through.
• Cooling is Key: Let the muffins cool completely before adding the glaze, otherwise it will melt and absorb into the muffin.
• Testing Doneness: Look for slightly golden edges and a springy top. The toothpick test is the most reliable.

Storage & Reheating

Store completely cooled muffins in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. For longer storage, freeze unglazed muffins for up to 3 months. To reheat, warm a muffin in the microwave for 15-20 seconds or in a 300°F oven for 5-10 minutes.

FAQ

Can I use low-fat sour cream?

For the best texture and moisture, full-fat sour cream is recommended. Low-fat may result in a slightly drier muffin.

Can I make these muffins dairy-free?

You can substitute the sour cream with a dairy-free plain yogurt and use a plant-based butter alternative. The results will vary slightly.

Why do my muffins have tunnels or are too dense?

This is almost always due to overmixing the batter once the dry ingredients are added. Mix just until combined, even if a few streaks of flour remain.

My streusel topping sank. What happened?

This can happen if the topping is too wet or if the batter is too thin. Make sure your streusel is crumbly and not like a paste, and ensure your batter is thick and spoonable.

Can I prepare the batter ahead of time?

It’s best to bake the muffins immediately after mixing. Letting batter sit can activate the baking powder too early, leading to less rise.

What can I use instead of maple syrup in the glaze?

You can substitute with an equal amount of honey or agave syrup, though the flavor profile will change.
