PREPARE EGG: In a small bowl, whisk 1 egg. Using a spoon, add 27g to a medium sized bowl.
Prepare Strawberries: If using frozen, please see notes section. Dice strawberries on a cutting board. Next, add to a bowl and leave behind any juice.
ADD FIRST INGREDIENTS: Now, melt coconut oil until it becomes liquid (warm but not hot). Add coconut sugar, diced strawberries, sourdough starter, salt, and coconut oil to the medium bowl with the egg.
MIX: Using a spoon, mix ingredients together until combined. DO NOT SKIP THIS STEP. Mixing wet ingredients prior to adding flour and baking soda will help achieve the perfect cookie texture.
ADD AND COMBINE: Now add flour, white chocolate chunks, and baking soda. Using the back of your spoon and/or your hands combine all ingredients until you form a ball.
STORE DOUGH: Place the dough covered in a small Tupperware or wrap it in plastic wrap. Be sure the dough is tightly sealed so it doesn’t become dry on the outside.
FERMENT DOUGH: Ferment the covered dough at room temperature for 10+ hours. You can ferment overnight or during the day, whatever works best for your schedule.
PREHEAT OVEN: When you’re ready to bake, preheat your oven to 350°F (177°C).
DIVIDE COOKIES: Divide and roll the cookie dough into 10-12 cookies, depending on how large you want your cookies to be. I like each cookie to weigh around 20-30g.
BAKE COOKIES: Bake for 6-8 minutes or until lightly browned on the sides.
LET COOKIES COOL: Remove from the oven and let cookies fully cool on the baking sheet (at least 1 hour)*. After 10 minutes, you can also pop them in the fridge or freezer to speed up the process. *It’s important to let the cookies cool so the ice cream doesn’t get too melty when you’re creating the ice cream sandwich.
ADD ICE CREAM: Now place a scoop of ice cream on top of one of your cookies. Use your scoop to gently spread the ice cream to the edges. Sandwich a cookie on top and gently press it all together.
FREEZE SANDWICHES: Now place the ice cream sandwiches on a plate and place them in the freezer for 15 minutes (so it firms up a bit). And that’s it! Enjoy!
