Chocolate Chip Donuts

Preheat oven to 350 degrees Fahrenheit (180 degrees Celsius) and grease a donut pan.
In a bowl, whisk together the flour, baking powder and salt. Set aside.
In a separate bowl, whisk together the melted and cooled butter, egg, brown sugar, granulated sugar, vanilla extract, milk, and yogurt until combined.
Add the dry ingredients to the wet ingredients and whisk until a batter forms. Add the mini chocolate chips and fold until evenly incorporated throughout the batter.
Gently spoon the batter into the donut cavities, or pipe them in using a piping bag/ziplock bag with the tip cut off (preferred method). Bake for 11-12 minutes until they are golden brown. To test, gently press your finger into the donut. It is ready if the donut bounces back.
Let the donuts cool in the pan for 5 minutes, then remove them onto a cooling rack to cool completely.

While the donuts are cooling, make the chocolate frosting. In a large, microwave-safe bowl, melt together the chocolate, butter and light corn syrup in 15 second increments, stirring in between each increment until completely smooth and melted. You can also do this over a double boiler.
Once the donuts are completely cool, dip one side of the donut into the melted chocolate. Top with mini chocolate chips if desired and enjoy! Store in an airtight container at room temperature.
