Preheat oven to 350 degrees.

In a bowl combine flour, baking powder, baking soda and salt set aside.

In a small bowl combine the coconut sugar and lemon zest, you will want to mix the zest into the sugar with your fingers. This is going to bring out lots of lemon extract and be amazing.

In a separate bowl combine the wet ingredients-  eggs, greek yogurt, lemon juice and vanilla.

Now add the melted butter to the coconut sugar and lemon mixture then add to the wet ingredient bowl. This will make sure the warm butter doesn’t coagulate.

Lastly add the wet mixture to the dry ingredients and combine. Mix blueberries and cornstarch/ arrowroot flour until blueberries are completely covered. Mix blueberries to the rest of the batter, pour into 8x8 pan that has been sprayed with oil and lined with parchment paper.

Bake for 35 mins.
