Chile Relleno Casserole

1.

Preheat the oven to 350 degrees Fahrenheit and lightly grease a donut pan with baking spray or butter.

2.

In a large bowl, whisk together the flour, sugar, baking powder, and salt until well combined.

3.

In another bowl, combine the milk, melted butter, vanilla extract, and egg, whisking until the mixture is smooth.

4.

Pour the wet ingredients into the dry ingredients and mix until just combined, being careful not to overmix.

5.

Gently fold in the fresh blueberries, ensuring they are evenly distributed throughout the batter.

6.

Carefully spoon the batter into the prepared donut pan, filling each cavity about three-quarters full.

7.

Bake in the preheated oven for 12-15 minutes until the donuts are golden brown and a toothpick comes out clean.

8.

Allow the donuts to cool in the pan for a few minutes before transferring to a wire rack to cool completely.
