Chewy Blueberry Oatmeal Cookie Recipe

These soft, chewy blueberry oatmeal cookies are a seasonal favorite. Packed with juicy blueberries and nutty oats, they make a memorable treat for breakfast, snacks, or dessert. Serve them to friends and family and they’ll quickly become a go-to recipe.

This is not your typical oatmeal cookie. Buttery and tender with a hint of cinnamon, these cookies are bursting with ripe blueberries — fresh produces the best texture, but frozen also works well when out of season.

June brings blueberry season, and for many families picking local berries is a beloved tradition. Oregon is a major producer of blueberries, and visiting U-pick farms is a great way to support local growers and enjoy perfectly ripe fruit.

Blueberries pair beautifully with many dishes — pancakes, bars, smoothies, muffins — and they freeze well so you can enjoy their flavor year-round. These cookies are an excellent way to use fresh or frozen berries and get that bright summer flavor into a chewy, satisfying cookie.

Why You Will Love These Blueberry Oatmeal Cookies

• Fresh blueberries give them a vibrant, fruity flavor different from typical oatmeal-raisin cookies.
• They consistently receive enthusiastic feedback — people love the texture and flavor.
• A touch of cinnamon complements the sweetness from the sugar and fruit.
• They’re a great way to use a large blueberry harvest; frozen berries are a fine substitute when fresh aren’t available.

Tips

• Let the cookies cool completely on the baking sheet before removing them — they set up as they cool.
• Press a few extra blueberries on top of each dough ball before baking for an attractive finish.
• If using frozen berries, add them straight from the freezer to avoid color bleeding into the batter; this preserves appearance.
• Coconut sugar gives a deeper flavor and helps produce a soft, chewy texture, but regular cane sugar works too.

FAQ

How To Make Blueberry Oatmeal Cookies

1. Preheat oven to 350°F (175°C).
2. In a stand mixer fitted with the paddle (or with a hand mixer), cream softened butter and coconut sugar until combined.
3. When the mixture begins to clump, add honey and beat until light and fluffy, about 3–5 minutes. Scrape down the bowl once or twice.
4. In a separate bowl, whisk together flour, oats, baking soda, baking powder, cinnamon, and salt.
5. Add the egg and vanilla to the wet mixture and combine on low speed.
6. Gradually add the dry ingredients to the wet until just combined. Avoid overmixing to keep cookies tender.
7. Gently fold in the blueberries, taking care not to mash them.
8. Scoop dough onto a parchment-lined baking sheet. Press a few extra blueberries on top if desired.
9. Bake for 14–18 minutes for larger cookies or 12–15 minutes for smaller cookies, until edges are golden.
10. Allow cookies to cool completely on the baking sheet before removing. Store at room temperature for short-term use or refrigerate/freeze leftovers.

Notes

• Coconut sugar tends to create a softer, chewier cookie with a richer flavor, but regular sugar is a fine alternative.
• Wait for the cookies to cool fully on the pan before transferring.
• Frozen blueberries can be used; add them straight from the freezer to keep colors and texture best.
• For gluten-free results use a 1-to-1 gluten-free flour blend and certified gluten-free oats if necessary.
