Perfect for kitchen adventures with young ones, these cookies are not just fun to make but also a guaranteed crowd-pleaser!
In a large bowl, mix wet ingredients – sourdough discard, melted coconut oil, cane sugar, brown sugar, and milk. Mix them together to get a smooth almost velvety liquid.
Gradually add dry ingredients – oats, flour, baking soda, and sea salt. Mix until just combined. Stir in raisins.
The next day, let the dough sit at room temperature for about an hour before you start turning it into cookies. Preheat oven to 350°F. Line a cookie sheet with parchment paper.
Shape dough into balls and flatten them into thick discs; the cookie dough will be quite tough. Place on the prepared baking sheet, leaving inches of space between each.
Bake them at 350°F (about 190°C) for 10-12 minutes until golden brown. Cool on a wire rack.
