🧰 Equipment Needed

• Mixing bowls
• Electric mixer
• Baking sheets
• Parchment paper
• Spatula
• Cookie scoop

🛒 Ingredients

Dry Ingredients

• 2 ¼ cups all-purpose flour
• 1 tsp baking soda
• ½ tsp baking powder
• ½ tsp salt

Wet Ingredients

• 1 cup unsalted butter, softened
• 1 cup brown sugar
• ½ cup granulated sugar
• 2 large eggs
• 1 tbsp vanilla extract

Mix-Ins (the Fun Part!)

Use 1 ½–2 cups total, such as:

• ½ cup chocolate chips (milk, dark, or both)
• ½ cup holiday M&Ms
• ¼ cup crushed pretzels
• ¼ cup toffee bits
• ¼ cup white chocolate chunks
• 2 tbsp festive sprinkles
• Optional: mini marshmallows (fold in at the end)

Topping

• Flaky sea salt
• Extra mix-ins for decorating

👩‍🍳 Directions

Step 1: Prep the Dough Base

Preheat oven to 350°F (175°C).
Line baking pans with parchment.

In a bowl, whisk together:

• flour
• baking soda
• baking powder
• salt

Set aside.

Step 2: Cream Butter & Sugars

In a large bowl, beat together:

• softened butter
• brown sugar
• granulated sugar

Mix until light, fluffy, and creamy (2–3 minutes).

Add eggs one at a time, beating well.
Mix in vanilla.

Step 3: Combine Wet & Dry

Add dry ingredients to wet and mix on low until just combined — do not overmix.

Step 4: Add the Mix-Ins

Fold in your loaded mix-ins:
chocolate chips, M&Ms, pretzels, toffee, sprinkles, etc.

Save a few for pressing onto the tops before baking.

Step 5: Scoop & Bake

Scoop dough using a cookie scoop (2–3 tbsp per cookie).
Place on baking sheet spaced 2 inches apart.

Press extra chocolate chips or M&Ms on top.
Sprinkle lightly with flaky sea salt.

Bake 10–12 minutes, until edges are set and centers look slightly underbaked — they firm as they cool.

Cool 10 minutes on baking sheet for perfect chewiness.
