Morning Bun Muffins (with crumble topping)
Everything a Morning Bun Is, Without the Laminated Dough
A proper morning bun is one of the great things a bakery can hand you through a window. Flaky, orange-scented, dusted in cinnamon sugar, still warm. It is also, frankly, a commitment to make at home. Laminated dough requires time and technique and a certain willingness to give up most of a Saturday.
This recipe takes everything that makes a morning bun worth getting out of bed for and puts it into muffin form. The orange. The cinnamon. The cardamom warmth underneath it all. The crunch on top. It gets you there in under an hour with a bowl and a whisk, and the result is the kind of muffin that makes your kitchen smell so good that people wander in from other rooms before they’re even fully awake.
The Orange Zest Step You Should Not Rush
Before a single dry ingredient gets weighed out, the recipe asks you to press orange zest into granulated sugar with your fingers. This is not a fussy detail. It is the step that makes the orange flavor actually show up in the finished muffin rather than fading into the background behind the spices.
Citrus zest holds its essential oils in the outer layer of the peel, and those oils are fat-soluble. Pressing and working the zest directly into sugar breaks the cells and releases those oils into the granules, infusing the sugar completely rather than leaving the flavor locked up in the zest. Every muffin in the batch carries that orange through from the very first mix. It takes about ninety seconds and it makes a real difference.
Spices That Belong Together
Cinnamon is the obvious one here and it deserves to be. A full tablespoon of it runs through both the batter and the crumble topping, which means it shows up in every single layer of the muffin. But the cardamom is what makes people stop and ask what’s in these.
Ground cardamom has a floral, slightly citrusy quality that pairs with orange in a way that feels almost inevitable once you taste it together. The nutmeg sits quietly beneath both of them, adding warmth without ever identifying itself directly. The spice blend as a whole reads as cozy and complex and distinctly not like a standard cinnamon muffin, which is the whole point.
Two Fats, One Very Good Reason
Using both melted butter and avocado oil in the same batter is a choice that shows up in the texture of the finished muffin. Butter brings flavor. Oil brings moisture that stays put even after the muffins cool, keeping the crumb soft the next morning instead of dry around the edges. Avocado oil in particular has a neutral flavor that lets the butter and orange and spice take center stage without contributing anything competing.
The sour cream is working quietly alongside them, adding tenderness and a faint tang that keeps the sweetness from going flat. All three fats together create a batter that bakes up with a tight, velvety crumb and a dome that holds.
The Crumble Is the Crown
A muffin with a crumble topping is already better than a muffin without one. This particular crumble, made with brown sugar, softened butter, flour, cinnamon, and a full orange’s worth of zest, is better than most crumbles. The orange in the topping echoes the orange in the batter, so the flavor carries all the way through from first bite to last crunch.
The texture is the key thing. The butter needs to be soft rather than melted so the crumble stays in distinct, sandy clumps rather than becoming a paste. Mixed gently with a fork until just crumbly, it bakes into something golden and slightly crisp on top while staying buttery underneath where it meets the muffin.
The Two-Temperature Bake
Starting the oven at 425°F and dropping it to 350°F five minutes in without opening the door is a technique worth understanding because it produces results that a single-temperature bake cannot replicate. The initial blast of high heat causes the leavening to activate rapidly, pushing the batter up quickly before a crust can form. The result is that tall, domed top that bakery muffins have and home muffins often don’t.
Once the dome has set, the lower temperature takes over and finishes the bake gently, cooking the center through without over-browning the outside or drying out the crumb. The oven door stays closed through the transition because opening it drops the temperature unevenly and disrupts the rise mid-climb.
Let them cool in the tin for at least ten minutes before pulling them out. The crumble needs that time to set into itself, and the muffin needs it to finish carryover cooking without falling apart in your hands.

- 80 g Sour Cream (room temperature)
- 240 g Milk (room temperature)
- 1 tsp Vanilla Extract
FOR THE CRUMBLE:

- 60 g All-Purpose Flour
- 1 tbsp Cinnamon
FOR THE ICING:
- 125 g Powdered Sugar
- 30 g Milk
- 5 g Vanilla Extract
Instructions
- In a large bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, cardamom, and nutmeg.
- In a medium sized bowl, add the sugar and orange zest. Pinch and press the zest into the sugar to release the orange flavor. Then whisk the eggs into the sugar. Add the melted butter, avocado oil, sour cream, milk, and vanilla. Whisk until smooth.
- Pour the wet ingredients into the dry and gently fold the mixture together until all of the flour is absorbed. Be careful not to over mix. Set the batter aside to rest.
- Preheat the oven to 425°F. Add the softened butter, brown sugar, orange zest, flour, and cinnamon to a small bowl. Gently mix until you create a crumbly texture.
- Add the muffin batter into a lined muffin tin, filling each liner 3/4 of the way full. Top each muffin with a generous scoop of the crumble topping.
- Bake the muffins for 5 minutes, then lower the heat to 350°F and bake for another 12-15 minutes until fully set (do not open the oven when lowering the heat.
- While baking, prepare the icing by whisking the powdered sugar, milk, and vanilla together until smooth. Wait to ice the muffins until they are cooled, otherwise the icing will melt into the muffin.
