1-First Step: Preheat and Prepare Your Pan Begin by preheating your oven to 350 degrees Fahrenheit and lining a 9×13 inch baking dish with parchment paper.

2-Second Step: Make the Caramel Filling Unwrap 11 ounces of caramels and combine them with 14 ounces of sweetened condensed milk and 4 tablespoons of unsalted butter in a small saucepan or microwave-safe bowl. Melt the mixture in the microwave at medium heat in 30-second intervals, stirring occasionally until smooth, or do it over medium-low heat on the stove.

3-Third Step: Mix the Dry Ingredients In a small bowl, mix 2 cups of all-purpose flour, 1 cup of old-fashioned oats, 2 ½ teaspoons of baking powder, and 1 teaspoon of salt.

4-Fourth Step: Cream the Wet Ingredients In a large mixing bowl, cream together 12 tablespoons of unsalted butter, ½ cup of creamy peanut butter, and 2 cups of light brown sugar until smooth and fluffy. Add the 2 large eggs one at a time, mixing well after each, then stir in 1 tablespoon of vanilla extract.

5-Fifth Step: Combine and Add Mix-Ins Gradually add the dry ingredients to the wet mixture, stirring until just combined to avoid overmixing. Then, fold in 2 cups of semi-sweet chocolate chips, 1 cup of peanut butter chips, and 1 cup of toffee bits for that signature crunch.

6-Sixth Step: Assemble the Bars Spread two-thirds of the dough evenly in the prepared pan, pressing it down with your hands or the back of a spoon. Pour the melted caramel mixture evenly over the dough, then drop the remaining dough by teaspoonfuls over the caramel.

7-Final Step: Bake and Cool Bake for about 30 minutes or until the top is golden and set, keeping an eye on it to prevent overbaking. Let the bars cool completely in the pan before cutting them into squares.
