4. Baking Tools That Make Life Easier
Here’s what you’ll need for a smooth baking experience:
- Mixing bowls (large and medium)
- Hand mixer or stand mixer
- Measuring cups and spoons
- Rubber spatula
- Baking sheets
- Parchment paper or silicone baking mat
- Cookie scoop (optional but helpful)
- Cooling rack
5. Step-by-Step Instructions
Step 1: Cream the Butter and Sugars
Start by creaming the butter, brown sugar, and white sugar together until light and fluffy. This typically takes 2–3 minutes on medium speed with an electric mixer.
Step 2: Add Eggs and Vanilla
Crack in the eggs one at a time, beating well after each addition. Then stir in the vanilla extract.
Step 3: Mix Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this to your wet mixture, stirring just until everything is combined. Don’t overmix—this keeps your cookies soft and chewy.
Step 4: Fold in the Chocolate and Marshmallows
Use a spatula to gently mix in the chocolate chips and mini marshmallows. For an extra visual swirl, reserve some marshmallows to press on top of each cookie before baking.
Step 5: Scoop and Chill
Scoop cookie dough into 2-tablespoon-sized balls and place them on a lined baking sheet. Chill the dough for at least 30 minutes before baking to prevent spreading.
Step 6: Bake
Preheat your oven to 350°F (175°C). Bake cookies for 10–12 minutes, or until edges are golden and centers are just set.
Step 7: Cool and Serve
Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack. Then—enjoy the swirl!
