In a big bowl, mix 1.5 cup of gluten free all purpose flour, 1/4 fine rice flour, 1/4 chick pea flour (a trick for making gluten free cake light and moist), 1 teaspoons of baking power, 1/2 teaspoon of baking soda and pinch of salt. Set aside.
In a mixer, add two large eggs, 3/4 cup of coconut sugar, 1/2 cup of melted & cooled butter. Blend and then add 2 tablespoons of scotch (yes!), grated lemon zest, cinnamon, vanilla extract. Blend well. Add the mixed flour above and 1 cup of plain gluten free yogurt. Blend at low speed. Add 1 cup of blueberry at the very end.
Pour into a baking tray lined with parchment paper. Bake at 350 F (176 C) for about 50 minutes or until it is done when the toothpick inserted into the cake comes out clean.
