Step 1: Preheat your oven to 350°F (175°C) to ensure even baking.
Step 2: In a large mixing bowl, combine the creamy cookie butter and light brown sugar. Blend until smooth and creamy. Add the egg and vanilla extract, mixing until fully incorporated.
Step 3: In a separate bowl, whisk together the all-purpose flour, cornstarch, cinnamon, baking soda, and a pinch of salt.
Step 4: Gradually add the dry mixture into the wet mixture, stirring gently until just combined.
Step 5: Adjust the dough consistency if too sticky by adding more flour, one tablespoon at a time.
Step 6: Using a spoon or cookie scoop, portion out the dough onto a prepared baking sheet, leaving space between each cookie.
Step 7: Bake for 10 to 12 minutes until edges are set but centers look slightly underbaked.
Step 8: Cool the cookies on the baking sheet for about 5 minutes before transferring to a cooling rack.
