Preheat oven to 350°F and line a muffin tin with 12 liners.
In a small bowl, whisk together flour, baking powder, baking soda, and unsweetened cocoa powder. Set aside.
1 1/2 cups all-purpose flour, 1 tsp baking powder, 1/2 tsp baking soda, 1/2 cup unsweetened cocoa powder
In another bowl, add eggs, sugar, vanilla, oil, milk, and yogurt, and whisk until well combined.
1 cups white sugar, 1 tsp vanilla, 2 eggs, 1/3 cup natural, greek yogurt, or kefir, 1/2 cup oil, 1/2 cup milk
Slowly add in dry ingredients until a smooth batter forms. Do not overmix.
Divide evenly between 12 muffin liners using spoons or an ice cream scooper.
Top off with a handful of strawberry slices and chocolate chips.
1 cup fresh strawberries, 1/3 cup semi-sweet chocolate chips
Sprinkle additional white sugar on top to give it that 'crispy' bakery style effect (optional).
Bake for 21-25 minutes. Once a toothpick comes out clean and you know they are ready, gently open your oven for 5 minutes to allow the heat to leave. If you take them out of the oven right away they will drop significantly.
Remove from oven and serve warm. Enjoy!
