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
- Preheat your oven to 375°F (190°C). Line a muffin tin with paper liners or grease the cups well.
- In a large bowl, combine the 1/2 cup vegetable shortening or softened butter and the first 1 cup of brown sugar. Beat together until creamy.
- Add the sour cream, eggs, and vanilla powder (use half this amount if you prefer less rich vanilla flavor) to the butter-sugar mixture. Mix until fully incorporated and smooth.
- In a separate bowl, whisk together the 2 cups all-purpose flour, rolled oats, kosher salt, baking powder, 1 1/2 teaspoons cinnamon, and nutmeg.
- Fold in the diced tart apples until evenly distributed throughout the batter.
- In a small bowl, make the streusel topping by mixing 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 your fingers or a fork to combine until it forms a crumbly texture.
- Divide the muffin batter evenly among the 15 prepared muffin cups. Sprinkle a generous amount of the streusel topping over each portion of batter.
- 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 to a wire rack.
- While muffins cool, prepare the glaze. In a small bowl, whisk together the powdered sugar, 1-2 tablespoons of milk (starting with 1), and the 2 tablespoons of dark maple syrup until smooth and pourable. Adjust with more milk if needed for desired consistency.
- Once muffins are completely cool, drizzle the maple glaze over the tops. Allow glaze to set before serving.
Variations
- Crunchy Top: Before baking, add a sprinkle of extra rolled oats over the streusel for added texture.
- Sugar-Free Glaze: Skip the powdered sugar glaze and simply drizzle the muffins with the dark maple syrup alone after baking.
- Mini Muffins: Bake the batter in a mini muffin tin for bite-sized treats, reducing the bake time to about 15-18 minutes.
- Serving Idea: Warm a muffin and serve it open-faced with a dollop of the leftover sour cream for a tangy contrast.
Tips for Success
- Use cold, diced apples and fold them in gently to prevent them from breaking down and making the batter watery.
- For the best streusel, ensure your butter is softened but not melted, so you can achieve a true crumbly texture.
- Let the muffins cool completely before adding the glaze, otherwise the warm muffins will cause the glaze to melt and run off.
Storage & Reheating
Store completely 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 15-20 seconds or in a 300°F oven for 5-8 minutes until warmed through.
FAQ
Can I use melted butter instead of softened for the streusel?
No, softened butter is key for creating a crumbly streusel texture. Melted butter will make the streusel more like a paste.
What type of tart apple is best?
Granny Smith apples are a perfect choice for their firm texture and tart flavor that balances the sweetness.
Why is there brown sugar listed twice?
The first cup is for the muffin batter itself, providing moisture and flavor. The second 2/3 cup is specifically for the streusel topping.
Can I make these without the glaze?
Absolutely. The muffins are delicious on their own with the streusel topping. The glaze adds extra sweetness and maple flavor.
My glaze is too thick or too thin. How do I fix it?
If too thick, add a tiny bit more milk. If too thin, add a little more powdered sugar. Adjust gradually until you reach a drizzle-able consistency.
How do I know when the muffins are done baking?
The tops should be golden and spring back lightly when touched. The most reliable test is inserting a toothpick into the center—it should come out with just a few moist crumbs, not wet batter.
