Step 1

Prep: Preheat the oven to 300°F. Spray a 9x13 pan with nonstick spray and set aside.

Step 2

Batter: With an electric mixer, cream the butter with the sugar until the mixture is light and fluffy.

Step 3

Add flour, baking powder and salt. Mix until it forms a dough.

Step 4

Bake: Press dough into prepared pan. Bake dough for 30-35 minutes, until golden brown.

Step 5

Remove from oven and let it cool for 10-15 minutes.

Step 6

Caramel Layer: Melt caramels and 2 TBSP milk in the microwave for 1 minute, adding 30 second increments as needed until caramels melt and mixture is mostly smooth. Pour on top of cooled cookie bars in pan. Refrigerate until set.

Step 7

Chocolate Layer: Melt 1 cup chocolate chips and 2 TBSP butter in the microwave for about 1 minute 30 seconds. Stir until smooth, then spread on top of the caramel, until even.

Step 8

Return pan to fridge for about 10 minutes. Melt remaining 2 TBSP chocolate chips and drizzle stripes on top, like the top of store-bought Twix bars have. Cut into squares while bars are still cold. (this makes cutting nice and even!) Enjoy!
