Instructions
Cupcakes
Prep – Preheat the oven to 350°F / 175°C. Line a 12-cup muffin pan with cupcake liners.
Chocolate – Melt the white chocolate in the microwave or over a double boiler. Set aside to cool until no longer hot.
Dry ingredients – In a bowl, whisk together the flour, cornstarch, baking powder, baking soda, and salt.
190 g All-purpose flour , 1½ tsp Baking powder, ½ tsp Baking soda, ¼ tsp Salt
Wet ingredients – In a large mixing bowl, cream the butter, oil, and sugar until combined. Add the eggs one at a time, beating well after each addition. Then add the vanilla and almond extract. Mix in the sour cream until well combined.
