Preheat the oven to 350°F. Grease a mini muffin pan and set aside.
In a medium bowl, mix together the flours, baking powder and baking soda. Set aside.
In a separate bowl, mix together the egg and sugar until fully combined. Add in the butter, milk and vanilla until fully incorporated.
Mix in the dry ingredients to the wet ingredients until just combined. Do not overmix! Fold in the chocolate chips and the strawberries.
Scoop some batter into the prepared muffin pan, around 3/4 full. Bake for 8-10 minutes. Remove and let cool.
