Mini Blueberry Upside Down Cakes are delightful individual desserts featuring a layer of caramelized blueberries topped with a moist, buttery cake. Once the cakes are inverted, they show off the glossy, sweet-tart blueberry topping! Perfect for entertaining or a simple special treat!
Preheat oven to 350 degrees. Spray a muffin tin with nonstick cooking spray.Divide the 2 tablespoons of butter and 1/4 cup light brown sugar between the 12 muffin tins. (I did this by cutting the butter into 12 little cubes)
Divide the frozen blueberries among the muffin tins (no need to thaw the blueberries first). Set aside.
Next add 1/3 cup butter, 1/2 cup granulated sugar and 1/4 cup light brown sugar to a stand mixer fitted with the paddle attachment. Cream for 3 minutes or until lighter in color and fluffy.
Add in egg and vanilla and mix until combined.
In a large bowl combine the flour, baking powder and salt. Slowly add the dry ingredients to the wet ingredients alternating with the milk.
Divide the batter evenly between the muffin tin.
Bake for 20-24 minutes or until the cakes look golden brown and set.
Allow the cakes to cool in the pan for 5 minutes.Run a knife along the sides of each cake to help it release then use a spoon to scoop it out then invert it onto a plate. Repeat with the remaining cakes.Serve warm with a scoop of ice cream!
