Blueberry Pudding Cake ブルーベリープディングケーキ

This is another one of my wife’s baking projects. This came about due to the convergence of two factors; one was the excess of blueberry puree we recently made from fresh blueberries for other baking projects and the other was that this is a variation on the theme of  PA Dutch chocolate pudding cake. Like the chocolate pudding cake, during the baking process, a cake layer forms on the surface and a pudding/sauce layer forms on the bottom. This recipe came together very quickly and the result was a nice vanilla cake with a rich blueberry pudding/sauce on the bottom. In this serving picture, in order to emphasize the lovely blueberry custard sauce, we scooped some of it on top of the piece of cake we served.

This is based on a recipe from the “Food and Wine” website but my wife deviated from the original recipe by substituting vanilla extract for the lemon juice/zest called for as flavoring in the original.

Ingredients
1 cup of pureed blueberries, 
1 cup of fresh whole blueberries not pureed
1/2 cup granulated sugar
1 1/2 teaspoons vanilla
1/2  teaspoon kosher salt
3/4 cup all-purpose flour
2 teaspoons baking powder
1/3 cup whole milk
1/4 cup unsalted butter, melted, plus more for greasing
1 1/4 cups boiling water

Directions:
To prepare the blueberries: Gently heat the blueberries on low heat until the skins burst and the berries exude juice. Puree the berries with an emersion blender. 

To prepare the cake layer: In a bowl whisk the flour, baking powder, and salt together. In another bowl mix the milk, melted butter and vanilla. Slowly pour the milk mixture into the flour mixture and stir until combined. Transfer the batter to a greased baking dish and spread in an even layer.* Spread the pureed blueberries over the batter. Arrange the whole fresh berries on the batter, pressing down slightly. Carefully pour boiling water evenly over the batter; do not stir.

Bake in a 425 F oven until the cake is golden brown and a warm, pudding-like sauce has formed on the bottom, 25 to 27 minutes. 

* I used the small square pyrex baking dish for this recipe but it was a bit too small. (It measured 7”x7”x2”) Although all the ingredients initially fit nicely in the dish, when the cake layer formed it expanded and the blueberry juice underneath fountained out all over the edges of the baking dish. Luckily I had put a tray under the baking dish when I put it in the oven otherwise it would have been quite a mess. Next time I will use a larger baking pan. (The next larger pan measures 8”x8.5”x2.5”)

This desert was as good an addition to the pudding cake family as the chocolate one mentioned above. The vanilla flavored cake was complemented by a thick blueberry flavored custard that formed underneath it. The custard had a very pronounced blueberry flavor and the fresh blueberries embedded in the batter formed nice additional burst and texture of blueberry. This was a wonderful summer dish celebrating blueberry season.
