Preheat oven to 375F
Mix dry ingredients in a bowl (oats through the sugar).
Whisk milk, eggs, yogurt, and vanilla in a separate bowl. Add wet ingredients to the dry and stir until just mixed.
Pour mixture into a 9x13 pan. Scatter blueberries or other fruit on top. You can also mix the fruit into the batter if you prefer it to be spread more throughout.
Bake for 35 minutes, until top is golden brown and oat meal is set. Serve warm.
