In a large mixing bowl, whisk together 2 cups plain flour, ¾ cup sugar, 2 teaspoons baking powder, ½ teaspoon salt, and 1 tablespoon cinnamon.

In a separate bowl, whisk 2 eggs until smooth, then add 1 cup milk, 1 teaspoon vanilla extract, and ½ cup melted unsalted butter.

Gradually pour the wet ingredients into the dry ingredients, gently folding together until smooth.

Preheat your oven to 350°F (175°C). Fill your greased donut pan cavities about two-thirds full with the batter.

Place the filled donut pan in the oven and bake for 20-25 minutes until light golden.

Let the donut bites cool in the pan for about 5 minutes before transferring to a wire rack.

Melt ½ cup unsalted butter in a small saucepan. In another bowl, mix ½ cup sugar with 2 teaspoons cinnamon.

Brush each donut with melted butter and roll in the cinnamon-sugar mixture until coated.

Melt 1 cup chocolate with ¼ cup cream over simmering water until smooth.

Dip the tops of the coated donut bites into the chocolate ganache and place back on the wire rack to set.
