Fastelavnsboller: Norwegian Lenten Buns Recipe

Fastelavnsboller, also known as Norwegian Lenten Buns, are pillowy cardamom-scented sweet buns traditionally filled with jam and fresh whipped cream, then dusted with powdered sugar. They were historically made to use up richer ingredients like butter, sugar and cream before Lent, and today they remain a beloved Scandinavian treat enjoyed from late winter through Easter.

Across the Nordic region these buns carry seasonal meaning: in Norway they are Fastelavnsboller, while in Sweden a similar bun called a semla often uses almond paste instead of jam. The dough is lightly flavored with cardamom and made tender with a small cooked flour-and-milk starter called tangzhong, which helps the buns stay soft for longer.

Ingredient notes

  • Yeast: The recipe uses instant (rapid-rise) yeast. You can use active dry yeast instead by proofing it in the warm milk for about 10 minutes (see Notes).
  • Cardamom: Ground cardamom is traditional; freshly ground whole seeds give the best aroma and a nice, slightly textured bite.
  • Filling: Raspberry jam works beautifully, but feel free to use any berry jam, lemon curd, pastry cream or a fruit compote.

Expert tips

  • Grind whole cardamom seeds for the freshest, most authentic flavor. The tiny flecks contribute aroma and texture.
  • Aim for a slightly tacky dough rather than a stiff one—resist adding extra flour. A soft dough yields the most tender buns.
  • If mixing by hand, expect kneading to take 8–10 minutes rather than the 3–4 minutes a mixer requires.

Recipe FAQs

Can I substitute active dry yeast? Yes. Proof active dry yeast in the warm milk for about 10 minutes until foamy, then proceed; quantities remain the same.

Can I make the buns ahead? Yes. After the first rise you can refrigerate the dough (well covered) for up to 24 hours before shaping. Or shape the buns, wrap them, and refrigerate overnight; allow about 45 minutes at room temperature before baking.

How should I store leftovers? Fresh is best, but cooled buns will keep in an airtight container at room temperature for up to 2 days. For longer storage freeze fully cooled buns in a sealed container for up to 3 months.

What is the tangzhong method? Tangzhong is a small cooked mix of flour and liquid that gelatinizes the starch, allowing the dough to absorb more moisture. It yields higher-rise, softer, moister buns that stay fresher longer.

Calories: 419 kcal (per bun)

Ingredients

For the tangzhong:

  • 5 tablespoons water
  • 5 tablespoons whole milk
  • 3 tablespoons all-purpose flour

For the dough:

  • 6 tablespoons melted unsalted butter, cooled
  • 1/2 cup whole milk, slightly warm
  • 2 teaspoons instant yeast (or active dry yeast, proofed)
  • 1/2 teaspoon ground cardamom (freshly ground preferred)
  • 1 teaspoon fine salt
  • 1/4 cup granulated sugar
  • 3 cups + 2 tablespoons all-purpose flour
  • 1 large egg
  • All of the cooled tangzhong

For the egg wash:

  • 1 large egg
  • 1 tablespoon water

For the whipped cream:

  • 2 cups heavy whipping cream
  • 3 tablespoons granulated sugar

To finish:

  • 3/4 cup raspberry jam (or other berry jam)
  • Powdered sugar for dusting (optional)

Instructions

  1. Make the tangzhong: Whisk water, milk and flour in a small saucepan until smooth. Cook over medium heat, whisking constantly, until the mixture thickens to a paste. Remove from heat and cool.
  2. Prepare dry ingredients: In a large bowl, whisk together yeast, cardamom, salt, sugar and flour.
  3. Combine wet ingredients: In the mixer bowl, combine cooled melted butter, warm milk, egg and the cooled tangzhong. Mix to combine, then add the dry ingredients gradually until a dough forms.
  4. Knead: Using a dough hook, knead on medium speed 3–4 minutes until the dough is slightly tacky, smooth and elastic. By hand, knead 8–10 minutes.
  5. First rise: Cover and let rise about 2 hours, until roughly doubled.
  6. Shape: Divide dough into 12 equal pieces. Shape each into a smooth ball by tucking edges under and rolling under your palm. Place on a parchment-lined sheet.
  7. Second rise: Cover lightly and let rise 45 minutes at room temperature.
  8. Bake: Preheat oven to 400°F (200°C). Whisk egg and water for egg wash and brush the buns. Bake 12–16 minutes until golden. Cool completely on a rack.
  9. Whip cream: When ready to serve, whip the cream with sugar until it holds medium to stiff peaks.
  10. Assemble: Slice off the top third of each bun to make a lid. Spread jam on the bottom half, add a generous spoonful or pipe of whipped cream, replace the lid and dust with powdered sugar. Serve immediately.

Notes

Active dry yeast substitute: Proof active dry yeast in the warm milk for 10 minutes until foamy, then add to the recipe in place of instant yeast.

Make-ahead options: After the first rise you can refrigerate the dough up to 24 hours before shaping, or shape the buns the night before and refrigerate them; allow them to come to near room temperature (about 45 minutes) before baking.

Storage and freezing: Store leftover buns in an airtight container for up to 2 days. For longer storage, freeze cooled buns in a sealed bag for up to 3 months. Reheat in a low oven until warmed through.
