A Memory in Cinnamon: My Grandmother’s Drawer
When I was a child, I thought sourdough cinnamon cardamom buns came from my grandmother’s hands. She would pull open the same wooden drawer every Sunday morning, one of those rickety, slightly warped drawers common in 1950s kitchens, the kind that didn’t slide out like the smooth ones we have today. It stuck slightly if it was humid, and frustrated the hell out of anyone that tried to open and close it. Inside, nestled between a small tin of dried lavender and a cracked bottle of vanilla, was a bundle of cinnamon sticks. She never used them whole. Instead, she would take one, wrap it in a tea towel, and crack it open with the bottom of her heavy ceramic mug. That first break, the moment when the woody bark splintered and the fragrance escaped was my favourite part.
She never told me where the cinnamon came from. Not because she didn’t know, but because she didn’t need to. To her, cinnamon was home. It was the scent of butter warming in a pan, of dough rising in a cool kitchen in spring in Ontario, of sugar melting into something golden and crisp. It wasn’t until much later that I learned the truth: that cinnamon—my cinnamon, my grandmother’s cinnamon—was never really ours at all.
The Origins of Sweet Breads and the Influence of the Spice Trade
Sweetbreads have been around across cultures for centuries. Long before sourdough cinnamon cardamom buns became part of our weekend rituals, ancient civilizations were mixing grains with honey and dried fruits, celebrating harvests, fertility, and feast days. In medieval Europe, enriched breads with butter and eggs were reserved for the wealthiest tables or for religious feasts. Spices were precious, and sweeteners were rare.
It wasn’t until the expansion of the global spice trade that things changed.
As goods began moving across the Arabian Peninsula, through India and Sri Lanka, and into ports controlled by Portuguese, Dutch, and British traders, Europe gained access to cinnamon, cardamom, nutmeg, and cloves. These spices, once hoarded by kings, eventually found their way into the kitchens of everyday people, especially in countries like Sweden, where a baking tradition was beginning to take root.
Cinnamon, native to Sri Lanka, was especially prized for its warm, resinous aroma. Cardamom, a citrusy, floral seed native to the forests of southern India, also became a staple in Scandinavian baking, brought north by way of Arab traders, the Ottomans, and eventually the spice companies of Europe.
In Sweden, these spices weren’t just added for flavour. They became part of culture woven into the fabric of fika, a daily ritual of coffee and pastries shared with friends and family.
Sweden’s Baking Heritage
By the 17th century, wheat flour, sugar, and butter were becoming more accessible, and with them came an explosion of sweet baking in Sweden. Buns spiced with cardamom (kardemummabullar), braided loaves, and the now-iconic kanelbulle, the cinnamon bun, began to appear in homes and bakeries.
Unlike the American-style cinnamon rolls that are heavy, icing-laden, and often cloying, Swedish sweet breads are gently spiced, lightly sweet, and intended for sharing. They are often made with care, slowly risen doughs, and a quiet reverence for tradition.
That’s the spirit behind these sourdough cinnamon cardamom buns.
They are built on time, not on shortcuts. The dough is fermented slowly using natural wild yeast. The filling is soft and spiced, not too sweet, just enough to warm your whole kitchen. And when you break one open, the texture is pillowy, soft, and aromatic with spice.
Technique Matters: Why the Order of Ingredients Counts
In many modern recipes, butter is thrown in at the start, the cinnamon gets dumped in the dough, and everything is mixed at once. But that’s not how our ancestors baked, and it’s not how good bread is made.
When making enriched doughs like this, butter should be added after the gluten has started to form. Fat shortens gluten strands, and adding it too early can prevent the dough from building the structure it needs. By kneading the dough first, then gradually incorporating softened butter one cube at a time, you get that perfect, silky, elastic result without losing strength.
As for cinnamon? It doesn’t go in the dough. It belongs in the filling. Cinnamon can inhibit fermentation when mixed directly into the dough, and its delicate aroma is better preserved when it's layered gently, rolled, and baked into soft spirals.
This Is More Than a Sourdough Cinnamon Cardamom Bun Recipe
These sourdough cinnamon cardamom buns are a story. Of trade winds and wooden drawers. Of cardamom pods cracked open in northern kitchens. Of the quiet, slow strength that comes from doing things properly, without rushing.
So the next time you’re tempted to toss everything into the mixer and speed your way through, remember: time is the ingredient that changes everything.
And somewhere in your dough, your flour, or your spice tin, you might just find the hands of your grandmother, too.

Ingredients
Dough:
- 200g active sourdough starter
- 320g whole milk
- 2 large eggs
- 120g softened butter
- 48g sugar
- 14g salt
- 720g bread flour
Filling:
- 120g softened butter
- 150g brown sugar
- 2 tbsp Ceylon Cinnamon
- 1 tsp ground Cardamom
Frosting:
- 200g cream cheese
- 80g softened butter
- 100g powdered sugar
- 1 tsp Mexican Vanilla Extract
Directions
Step 1: Prepare the Dough
Add the egg, sourdough starter, and sugar to the bowl of a stand mixer fitted with the paddle attachment. Mix to combine.
With the machine running, slowly pour in the milk. Add the flour and salt. Mix until a rough, sticky dough forms (about 1 minute). Scrape down the sides of the bowl.
Cover the bowl with a damp towel and let rest for 30 minutes.
Switch to the dough hook. Knead on medium-low speed (speed #2 or #3) for 6–8 minutes. The dough should be soft, supple, and pull away from the sides.
Gradually incorporate the softened butter, one piece at a time, allowing each addition to fully absorb. Continue kneading until the dough is elastic and slightly tacky.
Step 2: Bulk Fermentation + Cold Proof
Cover the dough and let it rest at room temperature for 2 hours.
Transfer to the fridge and cold proof for 12–18 hours.
Step 3: Shape the Buns
- The next morning, remove the dough from the fridge and let it rest at room temperature for 1 hour.
- Roll the dough into a 35x25 cm (9x12 inch) rectangle.
- In a small bowl, mix the softened butter, brown sugar, cinnamon, and cardamom into a smooth filling.
- Spread the filling evenly over the dough, leaving a small border around the edges.
- Using a pizza wheel, cut the dough into 6 wide strips (about 5–6 cm each).
- Roll each strip tightly into a spiral to form tall, distinct buns.
- Arrange the spirals in a 35x25 cm (9x12 inch) ceramic pan, leaving space between each one to allow for expansion during proofing.
Step 4: Final Proof
Cover and let rise in a warm spot (such as an oven with the light on or near a sunny window) for 1 hour.
Buns are ready to bake when they look puffy, jiggly, and spring back slowly when pressed.
Step 5: Bake
Preheat the oven to 175°C (350°F).
Bake for 25–30 minutes, until golden brown and fully set in the centre.
Step 6: Frost
Beat cream cheese and butter until smooth.
Add powdered sugar and vanilla extract. Mix until creamy.
Spread frosting over warm buns and serve.
