Preheat your oven to 350°F and line an 8x8 inch pan with parchment paper. In a large bowl, cream the softened butter and powdered sugar until light and fluffy, about 3 minutes. Add vanilla extract and salt, mixing until combined. Gradually incorporate flour until a soft dough forms. Press this dough evenly into your prepared pan and bake for 18-20 minutes until edges are lightly golden.

While your shortbread cools completely, prepare the caramel. In a heavy-bottomed saucepan, heat granulated sugar over medium heat, stirring constantly until it melts and turns amber colored. Slowly whisk in heavy cream (it will bubble vigorously), then add butter and stir until smooth. Cook for 2-3 more minutes until thickened. Pour this caramel over your cooled shortbread and refrigerate for 30 minutes.

Melt chocolate chips with coconut oil in a microwave-safe bowl, heating in 30-second intervals and stirring between each until smooth. Pour this chocolate over the set caramel layer and spread evenly with an offset spatula. Refrigerate for another 30 minutes until chocolate sets completely.

Using a sharp knife warmed under hot water and dried, cut your Homemade Twix Bites into small squares. Clean the knife between cuts for the cleanest edges.
