Final Thoughts

Ingredients

• 100g active levain starter (7–10 days old, bubbly, fed the night before)
  
• 40g cold unsalted butter, softened
  
• 100g light brown sugar, packed
  
• 1 large egg, room temperature
  
• 170g all-purpose flour (plus extra for dusting)
  
• 1 tsp fine sea salt
  
• Optional fillings: high-quality chocolate chunks, macadamia nuts, or dried cranberries

Instructions

1. Activate & prep your levain: Use your bubbly starter—no need to propagate unless your starter is weak.

2. Mix dry ingredients: In a large bowl, whisk flour, sea salt, and brown sugar together. Set aside.

3. Cream butter & sugar: In a separate bowl, cream softened butter and brown sugar until light and fluffy—this adds moisture and chew.
