Ingredients (Makes about 24 cookies):
Wet Ingredients:
- ½ cup (1 stick) unsalted butter , melted
- ½ cup packed brown sugar
- ¼ cup granulated sugar
- 1 large egg
- 1 tsp vanilla extract
Dry Ingredients:
- 1 cup all-purpose flour
- ½ tsp baking soda
- ½ tsp ground cinnamon (or more if you love spice)
- ¼ tsp salt
- 1½ cups old-fashioned oats (not instant – for best texture)
- ½ cup raisins (optional – or swap for chocolate chips or dried cranberries)
Instructions:
Step 1: Preheat Oven & Prep Baking Sheet
Preheat oven to 350°F (175°C) .
Line a baking sheet with parchment paper or silicone mat to prevent sticking.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together:
- Flour
- Baking soda
- Cinnamon
- Salt
Set aside while preparing the wet mixture.
Step 3: Combine Wet Ingredients
To the same bowl, add:
- Melted butter
- Brown sugar
- Granulated sugar
- Egg
- Vanilla extract
Stir until fully combined and smooth.
Step 4: Add Oats & Mix-Ins
Stir in:
- Oats
- Raisins or other mix-ins (chocolate chips, nuts, etc.)
Mix until everything is evenly incorporated. The dough will be thick and sticky—that’s normal!
Step 5: Scoop the Dough
Using a cookie scoop or tablespoon, drop rounded mounds onto the prepared baking sheet, spacing them at least 2 inches apart.
Step 6: Bake Until Golden
Bake at 350°F (175°C) for 10–12 minutes , or until the edges are golden and the centers look set but still soft.
Let cool on the baking sheet for 5 minutes , then transfer to a wire rack to finish cooling.
Cookies firm up as they cool—don’t worry if they seem soft at first!
Step 7: Serve & Enjoy
Serve warm with a glass of milk, coffee, or tea.
Store in an airtight container for up to 5 days , or freeze for longer storage.
Tips for Success:
- 🧁 Use Old-Fashioned Oats: For best texture—avoid instant or quick oats unless necessary.
- 🧊 Chill for Shape: If the dough feels too soft, refrigerate for 10–15 minutes before scooping.
- 🍫 Add Chocolate Chips: Stir in ½–¾ cup chocolate chips for a sweeter version.
- 🌰 Nutty Twist: Add ¼ cup chopped walnuts or pecans for extra crunch.
- ❄️ Freezer-Friendly Dough: Freeze cookie dough balls and bake straight from frozen—add 2–3 minutes to baking time.
Serving Suggestions:
- Perfect with coffee, tea, or a cold glass of milk.
- Great in lunchboxes, snack packs, or after-school treats.
- Pair with yogurt or a fruit plate for balance.
