Ingredients You’ll Need

You only need five simple ingredients to make these cookies:

2 cups rolled oats – Use old-fashioned oats for the best texture.
1 cup mashed banana – Acts as a natural sweetener and binder.

½ cup peanut butter (or almond butter) – Adds richness and helps hold the cookies together.
½ cup raisins – You can also use dried cranberries or chopped dates for a twist.
1 teaspoon cinnamon – Adds warmth and depth of flavor.

Tools You’ll Need

Parchment paper or silicone baking mat
Wire cooling rack

How to Make 5-Ingredient Oatmeal Raisin Cookies

Step 1: Preheat & Prepare the Baking Sheet
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat to prevent sticking.

Step 2: Mix the Ingredients
In a large mixing bowl, combine the mashed banana, peanut butter, and cinnamon. Stir until smooth. Add the oats and raisins, and mix until everything is well combined.

Step 3: Shape the Cookies
Scoop tablespoon-sized portions of dough and roll them into balls. Place them on the prepared baking sheet, about 2 inches apart. Gently press down on each ball to flatten slightly.

Step 4: Bake
Bake the cookies for 12-15 minutes, or until the edges are golden and the tops are set. Be careful not to overbake! The cookies will firm up as they cool.

Step 5: Cool & Enjoy
Let the cookies rest on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. Then, dig in and enjoy!

What to Serve with These Cookies

These oatmeal raisin cookies are delicious on their own, but if you want to take things up a notch, try pairing them with:

A glass of almond milk – A wholesome, dairy-free pairing.

A dollop of yogurt – Perfect for a quick breakfast or snack.
A cup of tea or coffee – The warm spices pair beautifully with your favorite hot drink.
A drizzle of honey – For an extra touch of sweetness.

Tips for the Best Oatmeal Raisin Cookies

Use ripe bananas. The riper they are, the sweeter and easier they are to mash.
Don’t overbake. The cookies will look soft when they come out of the oven, but they’ll firm up as they cool.
Let them cool before handling. This helps them set and hold their shape.

Experiment with mix-ins. Try adding chopped nuts, shredded coconut, or even dark chocolate chips for a fun twist.

How to Store These Cookies

Room Temperature: Store in an airtight container for up to 5 days.
Refrigerator: Keep in an airtight container for up to 2 weeks for a firmer texture.

Freezer: Freeze the baked cookies for up to 3 months. Let them thaw at room temperature before enjoying.
Freezing Cookie Dough: Roll the dough into balls and freeze on a baking sheet. Once frozen, transfer to a zip-top bag and bake directly from frozen (just add 1-2 extra minutes to the baking time).

Frequently Asked Questions (FAQ)

Can I use quick oats instead of rolled oats?

Can I make these without peanut butter?
