📝 Preparation Steps
1
For the toffee: Line a 9-by-9-inch baking pan with foil. Spray the foil with cooking spray.

2
In a medium saucepan, melt the butter over medium heat. Add the brown sugar and bring to a boil, stirring constantly until the mixture forms a golden caramel and the temperature reaches 290°F, 4 to ⏱️ 5 minutes.
3
Carefully pour the mixture into the prepared pan, allowing it to spread. Let the toffee cool and harden for about ⏱️ 20 minutes.
4
Place the toffee sheet in a large zip-top plastic bag and use a rolling pin to break the toffee into small pieces. There should be about 1 1/2 cups of toffee pieces.
5
For the cookie bars: Preheat the oven to 350°F. Line a 13-by-9-inch baking pan with parchment paper, letting the excess extend over the sides of the pan; spray the parchment with cooking spray.

In the bowl a stand mixer fitted with a paddle attachment, beat the butter and sugars on medium speed until the mixture has lightened in color and texture, 2 to ⏱️ 3 minutes. Reduce the mixer speed to low. Add the eggs, one at a time, and the vanilla, and beat until smooth, scraping the sides and bottom of the bowl as needed.

7
In another medium bowl, whisk together the flour, cornstarch, baking powder, and salt. Add the flour mixture to the butter mixture in 3 parts, mixing on low speed until fully incorporated after each addition. Scrape the sides and bottom of the bowl as needed. Using a rubber spatula, fold in 1 cup of M&M's, ½ cup of chocolate chips, and 1 cup of toffee pieces.
8
Spoon the batter into the prepared pan, pressing into an even layer. Sprinkle the remaining 1/2 cup of toffee pieces, 1/4 cup of M&Ms, and 1/4 cup of chocolate chips over the top of the batter.
9
Bake until a wooden pick inserted in the center comes out clean, 40 to ⏱️ 45 minutes.
10
Let the cookie bars cool at least ⏱️ 30 minutes before slicing.
11
Store the cookie bars in an airtight container at room temperature for up to 1 week.
