- Quick & Easy - There’s no creaming step, so your electric mixer can stay in the cabinet. In fact, you’ll have a fresh batch of dough for these zesty little treats ready in just 15 minutes.
- Made With Only 10 Simple Ingredients - Chances are, you already have more than half of what you need on hand.

As promised, you only need a few simple, easy-to-pronounce ingredients to make this lemon blueberry oatmeal cookies recipe:
- All-Purpose Flour - Plain white flour is all you need for the perfect cookie.
- Unsalted Butter - You could also use salted butter, but you’ll need to dial back the added kosher salt if you do.
- Lemon Zest - The zest of citrus fruit is loaded with flavorful essential oils. Make sure you’re only the bright yellow zest — the white pith is quite bitter.
- Egg - For binding the dough. If you forgot to let it come to room temperature, you can accelerate the process by placing it in a bowl of warm (but not boiling) water for about 10 minutes.
- Vanilla Extract - For rich, warm flavor. You’re welcome to use an equal amount of vanilla paste or vanilla powder, or use half as much ground vanilla bean instead.
- Oats - This must-have ingredient is the sole reason why these bites have such a delightfully chewy texture. Rolled old fashioned oats are best but quick oats will work as well (but the texture will be softer). Steel cut oats do not work here.
- Blueberries - Note that sadly blueberries have made it to EWG’s Dirty Dozen list, so opt for organic whenever possible. Otherwise, wash them thoroughly, preferably using produce soap to remove as many pesticides as possible before using for making blueberry muffins, blueberry pound cake or blueberry simple syrup!

⏲️ Substitutions & Variations
As much as I love this oatmeal blueberry cookies with the recipe as written, you’re always welcome to make any edits you need to make my recipes work for your family. Here are a few variations to consider when making these freshly-baked cookies:
- Gluten-Free - Feel free to swap in your favorite cup-for-cup all-purpose gluten-free flour blend (preferably with xanthan gum) instead, but be sure to give the dough a 30-minute rest before baking to allow the flour to rehydrate properly. If you skip this step, be warned: your cookies will likely end up grainy.
- Dairy-Free - Use vegan butter to make these treats safe for your lactose-intolerant friends.
- Go Nuts - Add another layer of flavor with a teaspoon of almond extract and up to ½ cup of sliced or slivered almonds.

💭 Recipe FAQs
I wouldn’t recommend it, as that would affect the total liquid makeup of the recipe. The juice of a lemon is also more acidic than the zest, which can affect how certain ingredients like the leavening reacts.
If you don’t have any fresh lemons on hand, I’d suggest using either a few drops of food-grade lemon essential oil (about 4-6 ought to do it), or using about a teaspoon of lemon extract instead.
I think scooping it out into individual cookie portions and freezing them in a single layer before transferring them to a freezer-safe container is the easiest way to do it. That way, you can easily bake off however many cookies at a time that you need without defrosting the whole batch!
Aside from leaving them at room temperature for about an hour, the easiest method is soaking them in their shells in a bowl of warm, but not boiling water, for about 60 seconds.
Due to the moisture of the fresh blueberries, these cookies should only be kept at room temperature for up to 3 days. You can extend the shelf life a bit by keeping the airtight container in the fridge for up to 5 days.
Alternatively, consider freezing some of the cookie dough balls for up to 3 months. When a cookie craving strikes, simply bake off the number of cookies your heart desires.
