How to Make the Recipe
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.
Step 2: Cream Butter and Sugar
In a large mixing bowl, cream together the butter, brown sugar, and granulated sugar until light and fluffy. This should take about 2-3 minutes.
Step 3: Add Eggs and Vanilla
Beat in the eggs one at a time, ensuring each one is fully incorporated before adding the next. Stir in the vanilla extract.
Step 4: Mix in Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until fully combined.
Step 5: Add the Fun Mix-ins
Stir in the oats, chocolate chips, candy hearts, pretzels, mini marshmallows, and any other mix-ins you want to include. The dough will be thick, so you may need to use your hands to fully combine everything.
Step 6: Form the Cookies
Scoop spoonfuls of dough and roll them into balls. Place them on the prepared baking sheet, spacing them about 2 inches apart.
Step 7: Bake the Cookies
Bake for 8-10 minutes, or until the edges are golden but the centers are still soft. Let them cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
Tips for Making the Recipe
- Chill the Dough: If you have time, chill the dough for about 30 minutes before baking. This will help the cookies hold their shape better and prevent spreading.
- Use a Cookie Scoop: A cookie scoop will ensure uniform cookie sizes and make the process faster and more efficient.
- Don’t Overbake: For soft, chewy cookies, pull them out of the oven when the edges are golden but the centers still look slightly undercooked. They’ll continue to firm up as they cool.
- Mix-ins Variety: Feel free to get creative with your mix-ins! You can add pretzels for a salty crunch or dried cherries for a fruity twist.
How to Serve
These Kitchen Sink Cookies are perfect for serving at a Valentine’s Day party or gathering. Pair them with a glass of milk or hot cocoa for an extra special treat. You can also serve them as part of a larger dessert table, or pack them up in cute bags or jars to give as gifts.
Make Ahead and Storage
Storing Leftovers
Store leftover cookies in an airtight container at room temperature for up to 5 days. If they start to lose their softness, pop them in the microwave for 10-15 seconds to soften them up again.
Freezing
You can freeze the cookie dough for later. Scoop the dough into balls, then freeze on a baking sheet. Once frozen, transfer the dough balls to a freezer-safe bag or container. When ready to bake, just place the frozen dough balls on a baking sheet and bake for a few extra minutes.
Reheating
To reheat leftover cookies, warm them in the oven at 300°F (150°C) for about 5-7 minutes to bring back their freshly-baked texture.
