Description
These rich and buttery crumb cake muffins capture all the goodness of a classic crumb coffee cake but in a perfectly portioned, handheld treat. For the best results, follow the recipe closely—divide the batter evenly into 15 muffins (no fewer) and chill the crumb topping to help it maintain its texture.
Ingredients
Crumb Topping
- 3/4 cup (150g) light or dark brown sugar
- 2 teaspoons ground cinnamon
- 1/2 cup (8 Tbsp; 113g) unsalted butter, melted
- 1 and 1/2 cups (188g) all-purpose flour (spooned & leveled)
Muffins
- 1 and 3/4 cups (219g) all-purpose flour (spooned & leveled)
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon ground cinnamon
- 1/2 teaspoon salt
- 1/2 cup (8 Tbsp; 113g) unsalted butter, softened to room temperature
- 3/4 cup (150g) granulated sugar
- 2 large eggs, at room temperature
- 3/4 cup (180g) full-fat sour cream, at room temperature
- 1 teaspoon pure vanilla extract
- 2 Tablespoons (30ml) milk (any kind)
Optional Vanilla Icing
- 1 cup (120g) confectioners’ sugar, sifted (sift after measuring)*
- 2–3 Tablespoons (30–45ml) milk (any kind) or heavy cream
- 1/2 teaspoon pure vanilla extract
Instructions
- Preheat oven to 350°F (177°C). Line a 12-count muffin pan with cupcake liners; line 3 cups of a second muffin pan with 3 liners (or bake in batches)—this recipe makes 15 muffins. Set aside.
- Make the crumb topping: Mix the brown sugar, cinnamon, and melted butter together in a small bowl until combined. Add the flour and use a fork to gently mix until crumbs form. Don’t over-mix into a paste. Just mix until it is crumbly. It will seem like a lot of crumb topping, and it is! These are generously topped. Place crumb topping mixture in the refrigerator while you make the muffin batter. Cold crumbs hold shape better when baking.
- Make the muffins: Whisk the flour, baking powder, baking soda, cinnamon, and salt together in a medium bowl. Set aside.
- In a large bowl using a handheld or stand mixer fitted with a paddle attachment, beat the butter and granulated sugar together on high speed until smooth and creamy, about 3 minutes. Scrape down the sides of the bowl as needed. (Here’s a helpful tutorial if you need guidance on how to cream butter and sugar.) Add the eggs and beat on medium speed until incorporated. Add the sour cream and vanilla, and beat until the mixture is combined and mostly creamy. (It’s ok if it appears somewhat curdled.) Scrape down the sides of the bowl as needed.
- With the mixer running on low speed, add the dry ingredients, followed by the milk. Avoid over-mixing—you may need to switch to stirring with a spatula or whisking by hand to be sure no flour pockets are hiding at the bottom of the bowl. Batter is thick.
- Spoon approximately 3 Tablespoons of batter into each of the 15 prepared muffin cups, filling them about 2/3 full. Spoon crumb topping on each, gently pressing it down so it adheres to the batter.
- Bake for 22–24 minutes or until a toothpick inserted in the center comes out clean. It’s normal for some of the crumb topping to fall off the sides as the muffins expand, but most should remain securely on top.
- Allow the muffins to cool for 5 minutes in the muffin pan(s), then transfer to a cooling rack to continue cooling. Let them cool for at least 15 minutes before icing.
- Make the icing (if using): Whisk the confectioners’ sugar, 2 Tablespoons milk or heavy cream, and vanilla extract together. Add another Tablespoon of milk or heavy cream to thin out if necessary. For thicker icing, add a little more confectioners’ sugar. Drizzle over muffins.
- Iced or plain muffins stay fresh covered at room temperature for a few days or in the refrigerator for up to 1 week.
Notes
- Freezing Instructions: Freeze baked & cooled muffins for up to 3 months. You can freeze with or without the icing, but making the icing fresh before serving is always best. Thaw in the refrigerator or at room temperature before enjoying. Warm up in the microwave if desired.

- Milk: You can use any milk, dairy or nondairy, in both the muffin batter and icing. For best taste and texture, I do not recommend nonfat milk.
- Confectioners’ Sugar in Icing: I use and recommend Domino brand confectioners’ sugar.
