Preheat oven to 350F. Grease or line a muffin pan with paper liners. If using paper liners, lightly spray the liners with non-stick cooking spray to prevent the muffins from sticking to the paper.
In a large mixing bowl, toss together the flour, chia seeds, baking powder, baking soda, and salt.
1 ¾ cup white whole wheat flour, 3 Tbsp chia seeds, 1 tsp baking powder, ½ tsp baking soda, ¼ tsp salt
In a medium bowl, whisk together the yogurt, avocado oil, honey, milk, eggs, lemon zest, and vanilla.
1 cup Greek yogurt, ⅓ cup avocado oil, ½ cup honey, ¼ cup milk, 2 large egg, 1 Tbsp lemon zest, 1 tsp vanilla extract
Add the wet ingredients to the dry ingredients and mix until just combined. Divide the batter evenly into the prepared pan.
Bake 20-22 minutes or until a toothpick inserted into the center comes out clean.
Once the muffins are completely cooled. Mix the powdered sugar and lemon juice until smooth and drizzle over muffins if desired.
⅓ cup powdered sugar, 2-3 tsp lemon juice
