What Are “Trash” Cookies?
Don’t let the name fool you! “Trash” cookies, or sometimes called “kitchen sink” cookies, get their name from the idea that you can throw in just about anything you have in your pantry—like a delicious, edible version of a trash can. It’s all about the chaotic, wonderful mix of ingredients that you wouldn’t typically find in a single dessert. This recipe celebrates that delightful randomness, creating a treat that’s packed with surprising textures and flavors in every single bite.
Ingredients You’ll Need
The beauty of Santa’s Trash Cookie Bars lies in the flexibility of the ingredients. Here’s our favorite combination, but feel free to get creative!
- White Chocolate Chips: This forms the sweet, creamy “glue” that holds everything together. Use a good quality brand for the best melting and flavor.
- Pretzels: Mini twists or snaps add a fantastic salty crunch.
- Potato Chips: A classic, sturdy, crinkle-cut chip works best here. They bring in that unexpected salty, savory note.
- Mini Marshmallows: For a soft, chewy texture that contrasts with all the crunch.
- Holiday M&Ms: These add a pop of festive color and a classic milk chocolate crunch.
- Festive Sprinkles: Because it’s not a holiday dessert without a little extra sparkle!
Step-by-Step Instructions
- Prep Your Pan: Line a 9×13 inch baking pan with parchment paper, leaving some overhang on the sides to act as handles. This will make removing the bars a breeze.
- Combine Dry Ingredients: In a very large bowl, gently mix together the pretzels, potato chips, mini marshmallows, and most of the M&Ms. Save a handful of M&Ms and the sprinkles for the topping.
- Melt the Chocolate: In a microwave-safe bowl, melt the white chocolate chips in 30-second intervals, stirring in between each one, until smooth and fully melted. Be careful not to overheat it.
- Mix Everything Together: Pour the melted white chocolate over the dry ingredients in the large bowl. Use a spatula to gently fold everything together until all the ingredients are evenly coated. Work quickly, as the chocolate will start to set.
- Press into Pan: Transfer the mixture to your prepared baking pan. Use the spatula or your hands (lightly greased) to press the mixture down into an even, compact layer.
- Add Toppings: Immediately sprinkle the remaining M&Ms and the festive sprinkles over the top. Gently press them into the bars so they stick.
- Chill to Set: Place the pan in the refrigerator for at least 1-2 hours, or until the bars are completely firm.
- Slice and Serve: Once firm, use the parchment paper handles to lift the entire block out of the pan. Place it on a cutting board and use a sharp knife to cut into squares.
Tips for the Best Trash Cookie Bars
- Work Quickly: Once the chocolate is melted, it will begin to set. Have all your ingredients prepped and ready to go so you can mix and press the bars before the chocolate hardens.
- Don’t Over-Crush: You want a mix of whole pieces and slightly broken bits for the best texture. Gently mix the ingredients to avoid turning everything into crumbs.
- Use Good Quality Chocolate: Since the white chocolate is the primary binding agent, using a good quality brand will ensure a smooth melt and a delicious, non-waxy flavor.
Fun Variations & Add-Ins
This is where you can really make the recipe your own. Try swapping or adding any of these delicious mix-ins:
- Different Chips: Try butterscotch, peanut butter, or semi-sweet chocolate chips.
- Nuts: Toasted pecans, walnuts, or peanuts would add another layer of crunch. For a similar flavor profile, check out these Pecan Pie Lasagna Bars.
- Dried Fruit: Dried cranberries or cherries would add a chewy, tart element perfect for the holidays.
- Other Snacks: Broken-up cookies (like Oreos), caramel corn, or different types of cereal would also be delicious. If you like no-bake holiday treats, you’ll love our No-Bake Christmas Cheesecake Bites.
Storage Instructions
Store your Santa’s Trash Cookie Bars in an airtight container at room temperature for up to 5 days. If your kitchen is very warm, you may want to store them in the refrigerator to keep them firm, but let them sit out for a few minutes before serving for the best texture. These bars do not freeze well, as the pretzels and chips can become soggy upon thawing.
