Our freezer friendly Blueberry Avocado Muffins are a popular recipe in our cookbook, From Freezer to Table. This easy breakfast idea packs some serious nutritional punch to your morning. And that tasty crumble topping takes these muffins to a whole different level.

Blueberry Avocado Muffins with Lemon Streusel Topping

I know what you’re thinking. “Avocado? In a muffin? Ladies, you’ve gone too far.”

Before you move on, allow me to make a case for these muffins. They are delish! We had quite a few of our blog readers test them to make sure we weren’t too wacky. They confirmed that these are a hit—even with their kids!

The avocado is virtually tasteless and replaces the oil and butter that is usually found in muffins.

To hide the hint of green that might throw a picky eater off, simply add the sweet and zesty crumble topping.

Blueberry Avocado Muffins with Lemon Streusel Topping are a delicious way to win breakfast. Yum-mm-mmy.



  • 1 cup unbleached all-purpose flour
  • ¾ cup whole wheat flour
  • ¼ cup ground flaxseed
  • 2 teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 large, ripe Hass avocado, pitted
  • ¾ cup sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 cup plain Greek yogurt
  • 1½ cups fresh blueberries

Lemon Streusel Topping (Optional)

  • ¼ cup whole wheat flour
  • ⅓ cup sugar
  • 1 teaspoon grated lemon zest
  • 3 tablespoons unsalted butter, cut into small pieces


1. To make the muffins: Preheat the oven to 375°F. Place silicone or paper liners in 15 cups in muffin pans or coat the cups with cooking spray.

2. In a medium bowl, mix together the flours, flaxseed, baking powder, baking soda, and salt.

3. Spoon the avocado flesh into the bowl of a stand mixer with a beater attachment. Beat on low until almost smooth. (If you don’t have a stand mixer, simply mash up the avocado as much as possible with a fork.) With the mixer still running on low, add the sugar. Once the sugar is mixed in, beat in the egg. Add the vanilla and yogurt and mix well.

4. Slowly add the flour mixture to the wet ingredients and mix until just blended, being sure not to overmix. At this point, the batter will be a bit thick. Using a spoon, gently fold in the blueberries.

5. Fill the muffin cups about three-fourths full, leaving room for the streusel topping.

6. To make the streusel topping: In a medium bowl, combine the flour, sugar, and lemon zest. Using a pastry cutter or a fork, cut in the butter until it resembles coarse crumbles.

7. Sprinkle the streusel topping evenly over the batter.

8. Bake for 25 to 30 minutes, or until a toothpick inserted in the center of a muffin comes out clean. Let the muffins cool in the pan on a rack for 5 to 10 minutes before removing. (Freezing instructions begin here.)

9. Serve warm or at room temperature.


TO FREEZE: After the muffins have cooled, place them in an airtight freezer container or freezer bag.

TO PREPARE FROM FROZEN: Wrap a frozen muffin in a moist paper towel and microwave in 30- to 60-second increments until warmed all the way through.

If you want to use frozen blueberries, just toss them in a bit of flour before stirring them into the mixture. This will prevent them from sinking to the bottom.

The streusel topping is optional. Feel free to leave it off if you are trying to avoid added sugar.

    These are amazing and only taste slightly avocado-like. I added a handful of spinach during the avocado step and added the Avocado, sugar, egg and yogurt to a blender with the spinach to add in a brighter green color for St. Patrick’s Day. My 2.5 year old loved them and so does my husband who is always wary of “healthified” recipes.

    hi there! can I substitute greek yogurt for a non dairy alternative like Silk dairy free yogurt and use flax egg? my son is allergic to dairy and eggs

      Hey Heather. I wish I had a good answer for you, but I haven’t tested these without those two ingredients. It sounds like your substitution ideas make sense to me. I think it’s worth a shot! Good luck.
