Homemade Sourdough Blueberry croissant

A cruffin is a mix of a croissant and muffin — flaky layers baked in a muffin tray. This version uses sourdough and blueberry filling.

Ingredients

Dough

  • 500g bread flour
  • 100g active sourdough starter
  • 250ml warm milk
  • 50g sugar
  • 1 egg
  • 8g salt
  • 60g soft butter

Butter Layer

  • 200g cold butter

Blueberry Filling

  • 1 cup blueberries
  • 3 tbsp sugar
  • 1 tbsp lemon juice
  • 1 tsp cornstarch

Topping

  • Powdered sugar

Step-by-Step Method

1. Prepare the Dough

In a large bowl:

  • Mix milk, sugar, egg, and sourdough starter.
  • Add flour and salt.
  • Knead until smooth.
  • Add soft butter and knead again for 8–10 minutes.

Cover and rest for 1 hour.

Then refrigerate overnight.


2. Prepare Blueberry Filling

In a saucepan:

  • Add blueberries, sugar, lemon juice, and cornstarch.
  • Cook on low heat for 5–7 minutes until thick.

Cool completely.


3. Laminate the Dough

  • Roll cold dough into a rectangle.
  • Place cold butter in the center.
  • Fold like a letter.
  • Roll and fold 3 times, chilling 20 minutes between folds.

This creates flaky croissant-style layers.


4. Shape the Cruffins

  • Roll dough into a thin rectangle.
  • Spread blueberry filling lightly.
  • Cut long strips.
  • Roll each strip into a spiral.

Place spirals into a greased muffin tray.


5. Final Proof

Cover and let rise for 2–3 hours until puffy.


6. Bake

Bake at:

  • 200°C (390°F) for 20–25 minutes

Until golden brown.


7. Finish

Cool slightly and dust with powdered sugar.

Serve warm.


Tips for Perfect Cruffins

  • Use very cold butter for flaky layers.
  • Don’t overfill with blueberries.
  • Chill dough whenever it becomes soft.
  • Active sourdough starter gives best rise and flavor.
