Ingredients
- Sourdough Starter – active starter or discard will both work.
- Eggs – one whole egg plus an extra yolk for richness.
- Butter – salted or unsalted, melted and slightly cooled before use.
- Almond Extract – or swap for vanilla if preferred; almond adds a richer note.
- Sugar – a mix of granulated and brown sugar for flavor and structure.
- All-Purpose Flour
- Cocoa Powder – regular store-bought cocoa works fine.
- Baking Soda and Baking Powder – both are included to produce a thicker, bakery-style cookie.
- Salt
- Chocolate Chips – a combination of semi-sweet and white chocolate chips plus optional milk chocolate pieces for topping.

How To Make Triple Chocolate Sourdough Cookies
Begin by combining the dry ingredients—flour, baking soda, baking powder, salt, cocoa powder, and two types of chocolate chips—in a large bowl. In a second bowl whisk the sourdough starter with melted butter, brown and granulated sugar, the egg plus extra yolk, and almond extract until smooth and caramel-like. Stir the wet mixture into the dry ingredients to form a thick, sticky dough. Chill the dough in the refrigerator before portioning.

This dough benefits from a cold ferment — overnight is ideal, but it can rest up to 48 hours. For large, bakery-style cookies use a 3-tablespoon scoop; you can make smaller cookies if you prefer. Roll scoops into balls, press them slightly flat, and top with milk chocolate pieces if using.
Kate’s Recipe Tip
- If cookies bake unevenly, reshape them while still hot by gently pressing a round cutter around the edges to form a neat circle.
- For variety, top cookies with a mix of white and milk chocolate pieces for extra contrast and meltiness.

How to Store + Freeze
Store at Room Temperature – Keep cookies in an airtight glass container for 4–5 days for best freshness. Avoid long-term storage in plastic if you can.
Freeze Once Baked – Freeze baked cookies flat on a tray, then transfer to a sealed bag or container. Thaw at room temperature before serving.
Freeze Before Baking – Freeze portioned dough balls on a tray until firm, then transfer to a zip-top bag for up to 3 months. Bake from frozen, adding a few minutes to the baking time.
