Preheat your oven to 350°.
In the bowl of a stand mixer, cream together the butter and sugar for 1 minute.
Scrape the sides of the bowl and add in the eggs, vanilla extract, and canola oil. Mix until well combined.
Add in the flour and baking powder. Mix until a soft dough forms.
Mix in the chipped Twix candy bars.
Scoop the cookie dough out in heaping 1/3 cup portions. Roll into a ball and flatten just slightly. Repeat with the remaining dough.
Arrange on a parchment paper or silicone baking mat covered pan. Place 6 cookies on each tray.
Bake at 350° for 14-16 minutes. The cookies will spread and the centers should puff up and no longer look wet.
Allow the cookies to cool completely on the pan before continuing.
Once the cookies have cooled, heat the caramel dip in the microwave until warm.
Spoon 2 tbsp of caramel onto the top of each cookie and spread to cover.
Melt the chocolate by microwaving chocolate chips in 30-second increments.
Spoon 2 tbsp of chocolate onto the top of each cookie and spread on top of the caramel, then immediately place a mini Twix candy bar.
Chill in the fridge for at least 30 minutes before serving.
Store in the fridge and serve chilled.
