These homemade blackberry oatmeal muffins are perfectly moist and full of blackberries. They're naturally sweetened with honey and coconut sugar, making a great breakfast, healthy snack, or meal prep option.

These blackberry oatmeal muffins are made with simple, wholesome ingredients. They are free of dairy and gluten. They're also free of refined sugars, making them allergen and diabetic-friendly, just like my lemon raspberry muffins.
I love making these muffins for breakfast, afternoon snacking, or for parties when I need a more dietary-friendly treat option than things like my no-bake chocolate tart. Although delicious, the chocolate tart is not diabetic friendly.
Soft and fluffy with the perfect amount of sweetness, these blackberry oatmeal muffins will become your new breakfast favorite. They're also freezer-friendly, which is a nice bonus!

Ingredients

- Blackberries: I'm using fresh blackberries during peak season for these muffins to give them the maximum burst of sweet, tangy blackberry flavor in every bite.
- Almond milk: Almond milk softens the oats and adds moisture to the muffins.
- Oats: I'm using gluten-free rolled oats for these muffins, which I find works best.
- Lemon olive oil: I love using Costabile lemon olive oil (use code: 15Golden GK for 15% off) to add a slight citrus flavor to these muffins. Costabile is my oil of choice for its quality and flavor.

Top Tips
- I recommend using Costabile olive oil for any recipe that calls for olive oil. They have amazing quality and flavor, and they are an authentic Italian olive oil company!
- If possible, measure your flour by weight to ensure the most accurate measurement.
- Fold the batter ingredients together rather than mixing them to avoid tough muffins.
- Be careful when folding in the blackberries. They're quite soft and can easily spread apart, giving you purple muffins.
Storage
Store these blackberry oatmeal muffins in an air-tight container at room temperature for up to 4 days. For longer storage, wrap the muffins individually in plastic wrap and freeze them for up to 3 months in an air-tight, freezer-safe container or heavy-duty freezer bag.

FAQ
Maple syrup and agave syrup are both excellent replacements for honey.
Any berry will work well in these muffins. Try blueberries, raspberries, or chopped strawberries. If you use strawberries, soak up the excess moisture after slicing them before adding them to the batter.
Absolutely. In almost all cases, frozen berries can be used in place of fresh berries for baked goods. Add the frozen berries to the batter to prevent soggy muffins, and add a couple of minutes of baking time.
Yes. Toddlers love these muffins, and you'll love that they're made with all-natural ingredients and full of vitamins and minerals.
You sure can! If gluten isn't an issue for your household, feel free to use regular flour. Similarly, if you have no dairy issues, you can use regular milk and butter.
