Preheat the oven to 350ºF.
Combine the softened butter, egg, maple syrup, and vanilla in a large mixing bowl, until smooth.
In a medium bowl, mix the dry ingredients with your mix-ins (sliced almonds, coconut, raisins, chocolate chips), until combined.
Add the dry ingredients to the wet ingredients until all of the flour is mixed in.
Scoop your cookie dough onto a baking sheet lined with parchment paper, using an ice cream scoop. Flatten each cookie dough ball to about 1/4" thick.
Bake the cookies at 350ºF for 8 to 10 minutes, or until lightly golden brown around the edges.
Allow to cool, and enjoy!
