Step-by-Step Instructions
Making Sourdough butter cookies is easy and fun. Just follow these steps.
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C).
Line a baking tray with parchment paper to prevent sticking.
Step 2: Cream the Butter and Sugar
In a large mixing bowl, add:

Mix well so the ingredients are evenly distributed.
Step 5: Combine the Dough
Slowly add the dry ingredients to the wet mixture.
Mix gently until a soft cookie dough forms.
Tip: Do not overmix the dough or the cookies may become tough.
Step 6: Shape the Cookies
Use a spoon or cookie scoop to form small balls of dough.
Place them on the prepared baking tray.
Leave some space between each cookie because they will spread slightly.
You can gently press the tops with a fork or spoon for a classic cookie shape.
Step 7: Bake the Cookies
Place the tray in the oven and bake for 10–12 minutes.
The edges should turn lightly golden while the centers stay soft.
