1/4 cup (30 g) white whole wheat or all-purpose flour
2 teaspoons granulated sugar
pinch of salt
1/3 cup (75 ml) milk
1 egg
1 tablespoon (15 g) butter, melted
a splash of vanilla extract
a sprinkle of ground cinnamon
1/2 cup (75 g) fresh or frozen blueberries
additional butter and sugar to prepare the skillet and sprinkle on the pancake
Preheat oven to 425℉ (218℃). Generously butter a 6-inch (15 cm) cast-iron skillet and sprinkle with sugar to coat. In a bowl stir together the flour, 2 teaspoons of sugar and pinch of salt. Whisk the egg, milk, melted butter, vanilla and cinnamon in another bowl. Add to the dry ingredients and whisk to combine. (The batter is quite thin.)
Pour the batter in the skillet and sprinkle the blueberries over the batter. (If using frozen blueberries don't thaw them.) Bake for 15 minutes at 425℉ (218℃) then reduce the oven temperature to 350℉ (175℃) and bake an additional 5-10 minutes until the center is set and the edges are puffed. Remove from the oven, sprinkle with sugar, remove from the pan and serve.
