Gathering Your Ingredients

Let’s keep it simple! You probably have most of this in your pantry already. Here’s what you’ll need for these easy oatmeal cookies:

Print

• 1 cup all-purpose flour
• 1 ½ cups old-fashioned oats
• ½ teaspoon baking soda
• ½ teaspoon ground cinnamon
• ¼ teaspoon salt
• ½ cup unsalted butter, softened
• ½ cup brown sugar, packed
• ¼ cup granulated sugar
• 1 large egg
• 1 teaspoon vanilla extract
• 1 cup fresh blueberries (if using frozen, do not thaw)

Let’s Make Some Cookies!

1. First, preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. This prevents any sticky situations later!
2. In a medium bowl, whisk together the flour, oats, baking soda, cinnamon, and salt. This is your dry team, and they’re ready to go.
3. In a larger bowl, use a hand mixer or a sturdy spoon to beat the softened butter, brown sugar, and granulated sugar together until it’s light and fluffy. This is the base of your delicious cookie dough.
4. Beat in the egg and vanilla extract until everything is just combined and smooth.
5. Now, gently add your dry team to the wet team. Mix until there are no more dry spots, but don’t overmix! A few flour streaks are okay.
6. This is the fun part: carefully fold in the blueberries. They’re delicate, so be gentle to avoid turning your dough purple.
7. Drop rounded tablespoons of dough onto your prepared baking sheet, spacing them about 2 inches apart. They need a little room to spread and get perfectly chewy.
8. Bake for 10-12 minutes, or until the edges are just turning golden brown. The centers might still look a little soft—that’s the secret to a soft cookie! Let them cool on the baking sheet for 5 minutes before transferring them to a wire rack.

My Favorite Tools for the Job

You don’t need anything fancy! A couple of mixing bowls, a baking sheet, and some parchment paper are the real MVPs here. A cookie scoop is a great tool if you have one, as it helps make all your cookies the same size so they bake evenly.

Tips, Tricks, and Yummy Variations

Baking is an adventure, and sometimes the best discoveries happen by accident! Here are a few things I’ve learned:

• Berry Burst: If you only have frozen blueberries, use them straight from the freezer to prevent too much juice from bleeding into the dough.
• Lemon Zest: For a brighter flavor, add the zest of one lemon to the dough. Blueberry and lemon are a match made in heaven.
• Storage: Keep these soft oatmeal cookies in an airtight container at room temperature for up to 4 days. If they last that long!
• Freezing: You can freeze the baked cookies for up to 3 months. Or, freeze the dough balls on a sheet pan and then toss them in a bag. Bake from frozen, adding a minute or two to the baking time for a fresh-baked cookie anytime.

This recipe became a staple in our house after I needed a last-minute treat for my daughter’s playdate. They were devoured in minutes, and I’ve been making them ever since!

What to Serve With Your Cookies

These cookies are fantastic all on their own with a cold glass of milk. For a real treat, crumble one over a bowl of vanilla ice cream or Greek yogurt. They also pair wonderfully with a hot cup of coffee or tea for your morning break. If you’re looking for more breakfast-inspired baked goods, you might enjoy these Banana Bread Muffins.

Your Blueberry Oatmeal Cookie Questions, Answered

Can I use frozen blueberries?

Absolutely! Just use them straight from the freezer. Tossing them in a tablespoon of flour from your measured amount before folding them in can help prevent them from bleeding too much color into the dough.

My cookies came out flat. What happened?

This usually means your butter was too warm. For the perfect texture, your butter should be softened but still cool to the touch. If it’s melty, your cookies will spread more.

Can I make these gluten-free?

You sure can! Simply swap the all-purpose flour for your favorite gluten-free 1:1 baking blend. I’ve had great success with this simple substitution.

How do I keep my cookies soft?

The key is not to overbake them! Take them out when the edges are golden but the centers still look soft. Letting them cool on the hot baking sheet for 5 minutes helps them set without becoming hard.

Can I add nuts or other mix-ins?

Of course! Feel free to add up to ½ cup of chopped walnuts, pecans, or even white chocolate chips. For another delicious flavor combination, try my Cranberry Orange Scones.
