Preheat the oven to 350F.
Grease two cake pans and line the bottoms with parchment paper. Set aside.
Mix together the milk and apple cider vinegar and set aside.
Sift together the flour, starch, baking powder, baking soda, and salt in a large bowl.
Beat together ¾ cup of coconut sugar with the butter on medium speed until fluffy. Add in the remaining sugar and oil and beat to combine.
Add the eggs two at a time and beat to combine after each addition.
Add the vanilla extract, milk mixture, and yogurt and mix to combine.
Add the dry ingredients and mix on low until just combined. If using a stand mixer, use the paddle attachment.
Toss the raspberries with 2 tablespoon of flour to coat then gently fold them into the batter with a rubber spatula.
Divide the batter between the cake pans and firmly tap the pans against the counter to break up large air bubbles. Bake for 35-40 minutes, until a toothpick comes out clean. If at sea level, I suggest checking the cakes at 30 minutes.
Once done baking, let cakes cool in their pans before flipping them out of their pans.
