Preheat oven to 350°F (175°C). Grease and line two 6-inch cake pans (or 24 cupcake liners).
In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
2 ½ cups all-purpose flour, 1 tbsp baking powder, ½ tsp baking soda, ½ tsp salt
In a large bowl, mix the sunflower oil, date paste, maple syrup, eggs, egg whites, and vanilla extract until smooth. Once mixed, add the sour cream.
½ cup organic high oleic sunflower oil, 1 ¼ cups date paste, 2 large eggs, 2 egg whites, 2 tbsp vanilla extract, ¾ cup sour cream, 3 tbsp maple syrup
Alternately add the dry ingredients with the milk, starting and ending with the dry ingredients. The batter should be thick but scoopable.
¾ cup whole milk
Using an ice cream scoop or large spoon, fill each cupcake liner about 2/3 of the way full. Bake 15-17 minutes, or until a toothpick inserted in the center comes out clean. Cool completely.
