Coffee Cake Muffins: Tender, Crumb-Topped & Easy
Storing and Serving
These muffins stay soft at room temperature for up to 3 days in an airtight container. To reheat, pop one in a 300°F oven for 5 minutes or microwave for 15 seconds. They also freeze beautifully — wrap unfrosted muffins individually in plastic wrap, then place in a zip-top bag. Thaw at room temperature or reheat from frozen in a 350°F oven for 10 minutes.
Serve them with a hot cup of coffee, obviously. Or with a tall glass of cold milk. They're breakfast, snack, or dessert — no judgment here.
Allergen Notes
This recipe contains wheat (gluten), dairy (butter, buttermilk), and eggs. For a dairy-free version, use plant-based butter and a buttermilk substitute (unsweetened almond milk + vinegar). For gluten-free, use a 1:1 all-purpose gluten-free flour blend. For specific dietary needs, please consult a qualified professional.
Takeaway: Coffee cake muffins are all about texture — a crunchy, buttery streusel top over a tender, tangy crumb. Use cold butter for the streusel, buttermilk for the batter, and a gentle hand when folding. That's the method. The rest is just baking.
Frequently Asked Questions
Can I use sour cream instead of buttermilk?
Yes. Substitute an equal amount of full-fat sour cream (1 cup). The muffins will be slightly denser but still very tender. If using sour cream, reduce the melted butter by 2 tablespoons to keep the fat balance right.
Why did my streusel sink into the muffins?
Streusel sinks if the batter is too thin or if you press the streusel in too hard. The batter should be thick and scoopable, not runny. Gently press the streusel so it just sticks — don't push it down. Also, make sure your butter is cold when making the streusel; warm butter melts too quickly and sinks.
How do I make these muffins gluten-free?
Use a 1:1 gluten-free all-purpose flour blend that contains xanthan gum. The texture will be slightly more delicate, so handle the batter gently. Bake time may vary by 2-3 minutes. For dietary advice, please consult a qualified professional.
Recipe: Coffee Cake Muffins
Equipment
- 12-cup muffin tin
- paper liners
- large mixing bowl
- medium mixing bowl
- whisk
- rubber spatula
- small bowl
- fork
Ingredients
- For the streusel: 1/2 cup (100g packed light brown sugar)
- 1/3 cup 42g all-purpose flour
- 1 teaspoon ground cinnamon
- 1/4 teaspoon salt
- 4 tablespoons 56g cold unsalted butter, cut into small cubes
- For the muffins: 2 cups (250g all-purpose flour)
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup 113g unsalted butter, melted and slightly cooled
- 3/4 cup 150g granulated sugar
- 1 large egg (at room temperature)
- 1 teaspoon vanilla extract
- 1 cup 240ml buttermilk, at room temperature
- For the glaze (optional: 1/2 cup (60g) powdered sugar)
- 1-2 tablespoons milk or buttermilk
Instructions
- Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners. This ensures easy release and keeps the streusel intact.
- Make the streusel: In a medium bowl, whisk together the brown sugar, flour, cinnamon, and salt. Add the cold butter cubes. Use a fork or your fingertips to cut the butter into the dry mixture until it resembles coarse, pea-sized crumbs. Do not overwork it — you want distinct clumps. Set aside.
- Make the muffin batter: In a large bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
- In another large bowl, whisk the melted butter and granulated sugar until combined — it will look like wet sand. Whisk in the egg and vanilla until smooth. The mixture should be pale and slightly thickened.
- Add half the dry ingredients to the wet mixture, then half the buttermilk. Stir gently with a rubber spatula just a few times. Add the remaining dry ingredients and buttermilk, and fold until just combined. A few streaks of flour are fine — overmixing makes tough muffins. The batter will be thick and slightly lumpy.
- Divide the batter evenly among the prepared muffin cups, filling each about 2/3 full. Use a small cookie scoop or two spoons for neat portions.
- Generously sprinkle the streusel over each muffin, pressing it gently into the batter so it sticks. Use all the streusel — pile it high; it will sink slightly as the muffins rise.
- Bake for 16-18 minutes, until the muffins are golden brown on top and a toothpick inserted into the center of a muffin comes out clean or with a few moist crumbs. The tops should spring back when lightly touched. Cool in the pan for 5 minutes, then transfer to a wire rack.
- For the glaze (optional): In a small bowl, whisk together the powdered sugar and 1 tablespoon of milk until smooth. Add more milk a teaspoon at a time if needed for a drizzling consistency. Drizzle over warm muffins.
- Serve warm or at room temperature. Store leftovers in an airtight container at room temperature for up to 3 days.
