The BEST Blackberry Muffins

Just like with all my baked goods, these blackberry oatmeal muffins are made with simple, wholesome ingredients.

My family always tend to gravitate towards blueberries or strawberries so this is a nice change of pace! Perhaps it may be for yours as well!

Soft and fluffy with just the right amount of sweetness, not only do these muffins taste divine, the blackberries impart a beautiful color that may totally pique your child’s interest ;).

I like to keep a variety of muffins in my freezer for an easy and healthy breakfast option as well as to add to lunch boxes.

If you do too, you must try these blueberry or raspberry muffins, ok? OK!

Or any of these sweet or savory muffins.


All t he ingredients laid out on a white background and labelled.

I am highlighting just the ones that need further explanation. The complete list is in the recipe card below.

  • Blackberries – Use fresh blackberries when in season. Frozen blackberries will work as well. Refer to the FAQ section below.
  • Milk and Greek yogurt – the combination of these two ingredients imparts great texture, flavor, and nutrition! I recommend using full fat, as it is essential for optimal brain development in the early years.
  • White whole wheat flour – You will love baking with this flour. It’s the same nutritionally as whole wheat flour but is lighter in texture and a little sweeter in flavor. You can use all-purpose flour, whole wheat, or a combination both.
  • Oats – rolled oats will work best but you can use quick oats. Steel cut oats will not work.
  • Baking powder and baking soda – be sure to check the expiration date so that your muffins will rise properly.
  • Lemon zest – adds incredible brightness to the muffins

Step by Step Instructions

  1. In a large mixing bowl, soak the oats first in milk and yogurt. You can skip if you are pressed for time BUT I highly encourage you to plan ahead and account for this extra time. The oats will absorb some of the liquid, resulting in soft, tender muffins
  2. Add the wet ingredients to the soaked oats.
  3. In a medium bowl, combine all the dry ingredients.
  4. Pour in the wet mixture. Be careful not to over mix.
  5. Scoop batter evenly into a 12-cup muffin tin. I like to use a silicone muffin pan because there’s no need to grease and the muffins just pop right out!
  6. Bake until a toothpick inserted into the center of a muffin comes out clean.

Variations and Substitutions

  • Dairy-free? Any plant-based Greek style yogurt and milk (such as unsweetened almond milk) will work. As for butter, use vegan butter or coconut oil. You can also use olive oil, if you prefer.
  • Egg-free? Use flax egg. In a bowl, combine 2 tablespoons of flaxseed meal (ground flaxseed) and 6 tablespoons of water. Allow the mixture to sit for 8-10 minutes until thickened like gel-like consistency.
  • Alternative to white whole wheat flour? You can use all purpose flour, whole wheat flour (muffins will be denser and heartier), or a combination of both.
  • Gluten-free? Use a 1:1 gluten free flour like this one and certified gluten-free oats. Almond flour will not work.
  • No blackberries? You can use whatever berries you wish – strawberries, blueberries, and raspberries will all be delicious in this recipe. During the fall season, you should totally add pears!
  • An alternative to honey? You can use maple syrup, over ripe banana, or unsweetened applesauce, if avoiding added sugars.
  • You can also add some chocolate chips for older kids.

Tips for Success (be sure to read!)

Toddler grabbing sliced blackberry muffin.
  • Slice the blackberries in half lengthwise to spread them throughout the muffins.
  • Use a spoon to scoop the flour into the measuring cup rather than scooping the flour out of the container or bag with your measuring cup. Using the latter method, you could end up with a lot more than what you need.
  • Take all the cold ingredients out of the refrigerator at least 15 minutes prior to baking.
  • Do NOT over-mix the muffin batter after combining the dry and wet ingredients. Mix lightly with a spatula until just combine. Otherwise you will end up with dense, tough muffins.
  • Blackberries are quite tender so gently stir into the batter.

Storage Suggestions

Transfer to an airtight container and keep on the counter for up to 2 days. You can also refrigerate or up to 4 days. Enjoy at room temperature or microwave briefly (no more than 15-20 seconds)

To freeze, I recommend flash freezing. Will keep for up to 3 months. Thaw in the refrigerator overnight.

Here’s a step-by-step guide on how to store and freeze muffins.

Frequently Asked Questions

Can I use frozen blackberries to make these muffins?

You can but be sure to use straight from the freezer! There is no need to thaw. Otherwise, you will end up with soggy muffins. You will also need to add 2-3 more minutes to your baking time.

Can I give these blackberry muffins to my baby?

Yes! The only change you have to make is to use 1 medium overripe banana (will be about 1/2 cup mashed) or ½ cup unsweetened applesauce instead of honey. That’s it!

Here’s a master list of healthy baby muffins that I believe your baby (and YOU) is going to love!
