Put frozen blueberries and cranberries in a small bowl. Mix with 1 teaspoon of whole wheat flour to coat the fruit. Set aside. Psst, sometimes I add more than 1 cup of blueberries (more like 1, ¼ cup). *Skip this step if using fresh blueberries and cranberries.
Preheat oven to 375°. Spray a 12-count muffin tin with non-stick cooking spray or lightly oil the inside of the muffin cups to prevent sticking. Set aside.
Mix flour, spices and baking powder together in a large bowl. Set aside.
In a separate medium bowl beat the sugar and oil. Whisk in the eggs and vanilla extract until combined. Then add yogurt and whisk until the lumps are out. Lastly add the milk and mix well.
Add the wet ingredients to the dry ingredients and mix well with a whisk. Fold in the blueberries and cranberries to the batter. Using a cookie scoop equally scoop out the batter into muffin tins. Bake for 20-22 minutes or until when a toothpick is inserted into the middle it comes out dry.
Best enjoyed warm or room temperature!
Notes
Oil
You can swap canola oil for extra light baking olive oil.
Sugar
You can use white or brown sugar. I have tested this recipe with coconut sugar which you could use as well. If you'd like it "sweet enough" when using the coconut sugar I would recommend to increase the amount and go up to ¾ cup. Of course you can play around with it for your preferred level of sweetness.
Flour
For this recipe I like using 1 part all purpose flour and 1 part whole wheat flour. Freel free to sub all purpose flour for oat flour. I wouldn't use all whole wheat flour for this recipe because that would require tweaking ingredient amounts to add more moisture.
Yogurt
Any type of Greek yogurt would work (nonfat, full fat). I have not tried this recipe with non-dairy yogurts.
Don't like cranberries? No problem! You can use all blueberries.Nutrition values are approximate and vary based on the products used.
