Preparation Phase & Tools to Use

To make Santa’s Trash Cookie Bars successfully, having the right tools makes all the difference. A sturdy mixing bowl is essential for evenly combining ingredients, while a hand or stand mixer helps create a smooth, creamy dough base. A rubber spatula ensures nothing goes to waste and helps fold in all those fun mix-ins without overworking the dough.

You’ll also need a baking pan for shaping the bars—lined with parchment paper for easy removal—and a measuring set to keep your ingredient ratios precise. Each tool plays a role in achieving the perfect chewy texture and evenly baked result.

Butter brings richness and creates that soft, melt-in-your-mouth texture.

Brown sugar adds moisture and a deep caramel-like sweetness.

Granulated sugar balances the flavor and helps create slightly crisp edges.

Eggs provide structure and help bind everything together.

Vanilla extract enhances the overall sweetness with a warm aroma.

All-purpose flour forms the base of the bars and gives them structure.

Baking soda helps the bars rise slightly and stay soft.

Salt balances the sweetness and intensifies flavors.

Chocolate chips add gooey pockets of chocolate throughout.

Holiday candies (like M&Ms) bring color and crunch.

Crushed pretzels add a salty contrast and texture.

Mini marshmallows create soft, sweet bursts in every bite.

Step 1: Prepare the Oven and Pan

Preheat your oven to 350°F (175°C) and line a baking pan with parchment paper for easy removal.

Step 2: Cream Butter and Sugars

In a mixing bowl, beat the butter, brown sugar, and granulated sugar until light and fluffy.

Step 3: Add Wet Ingredients

Mix in the eggs one at a time, then stir in the vanilla extract until fully combined.

Step 4: Combine Dry Ingredients

In a separate bowl, whisk together flour, baking soda, and salt.

Step 5: Mix Everything Together

Gradually add the dry mixture to the wet ingredients, mixing until a soft dough forms.

Step 6: Fold in the Fun Mix-Ins

Gently fold in chocolate chips, candies, pretzels, and marshmallows.

Step 7: Spread and Bake

Press the dough evenly into the prepared pan and bake for 25–30 minutes or until golden on top.

Step 8: Cool and Slice

Allow the bars to cool completely before cutting into squares for clean edges.

Serve these bars slightly warm for gooey chocolate goodness or at room temperature for a firmer bite. They pair wonderfully with a glass of milk or hot cocoa.

To store, keep them in an airtight container at room temperature for up to 4 days. For longer storage, refrigerate or freeze them—just let them come to room temperature before serving for the best texture.
