Preheat the oven to 350 F. Line a 12 cup muffin pan with paper liners. In a medium bowl, whisk together flour, pudding mix, salt, and baking soda.
In a large bowl, mix butter with both granulated and brown sugar until fluffy. Add in the egg and vanilla extract, and mix until smooth. Add in the flour mixture, mix until it is fully combined. Fold in the chocolate chips.
Evenly press the cookie dough into the prepared paper liners. Bake for 12-15 minutes.
