2 cups All-Purpose Flour Provides structure; swap for a 1:1 gluten-free flour blend if desired.
2 Tbsp. Cornstarch Increases softness and chewiness; can be omitted but will change the texture.
1 tsp. Baking Powder Acts as a leavening agent; avoid substituting with baking soda.

How to Make Chocolate Toffee Cookie Bars
Preheat the oven to 350°F (175°C) and prepare a 9×13-inch baking pan by coating it with cooking spray or lining it with parchment paper for easy removal.
Cream together the unsalted butter, dark brown sugar, and granulated sugar in a large mixing bowl until it becomes light and fluffy. This should take about 3-5 minutes for that dreamy texture.
Add the eggs one at a time, mixing well after each addition. Then, gently stir in the vanilla extract for that aromatic flavor boost.
Whisk together the flour, cornstarch, baking powder, and kosher salt in a separate bowl until well combined. This step ensures even distribution of dry ingredients.
Mix the dry ingredients into the wet mixture gradually, stirring until just combined. Avoid over-mixing to keep the bars chewy and rich.
Fold in half of the M&M’s and semisweet chocolate chips, letting their vibrant colors and sweet flavors mix seamlessly into the batter.
Spread the batter evenly into the prepared baking pan, ensuring it reaches the corners. Then, sprinkle the remaining M&M’s and chocolate chips on top for extra crunch and color.
Bake in the preheated oven for about 25-30 minutes or until the edges are golden brown and a toothpick inserted into the center comes out clean.
Cool the cookie bars in the pan on a wire rack until fully set. Patience is key here; allowing them to cool completely helps maintain their structure.
Store the cooled chocolate toffee cookie bars in an airtight container at room temperature for up to three days, or freeze for longer storage.
Optional: Drizzle with melted chocolate before cutting for a decadent finishing touch.

Eggs should also be at room temperature; you can place them in warm water for about 5-10 minutes to quickly bring them up to temperature if you’re in a rush.
How should I store leftover Chocolate Toffee Cookie Bars?
To keep your chocolate toffee cookie bars fresh, store them in an airtight container at room temperature for up to 3 days. If you want to extend their life, you can place them in the fridge, where they’ll stay good for about a week, though they may lose a bit of their desired chewiness.

They can be frozen for up to 3 months. When you’re ready to enjoy, simply thaw in the fridge or at room temperature.
What should I do if my cookie bars come out too dry or crumbly?
The more the merrier! If your cookie bars turn out dry, you may have overmixed the batter or baked them too long. Ensure that when combining wet and dry ingredients, you mix just until combined, and always check for doneness a few minutes before the timer goes off look for edges turning golden brown and a fork or toothpick inserted into the center should come out clean but not completely dry.
Are Chocolate Toffee Cookie Bars safe for people with nut allergies?
If you re catering to guests with nut allergies, just make sure to avoid mixing in nuts, as they can pose a risk. Additionally, check that all chocolate products you use are nut-free, as cross-contamination can sometimes occur in manufacturing.
What if I don’t have certain ingredients like cornstarch or baking powder?
No worries! If you don t have cornstarch, you can omit it; just note that it may affect the chewiness slightly. As for baking powder, it s crucial for the bars to rise; you can substitute it with a mix of 1/4 teaspoon baking soda plus 1/2 teaspoon vinegar for a temporary fix, but I often recommend sticking to what s listed in the recipe for best results.
