Use a 9” deep cake pan, I didn’t have one so I used a rectangular one 8” x 11”. Brush some melted butter on the insides and then line the bottom with baking paper.
Mix the blueberries in the cake pan with 2 Tb sugar, 2 Tb lemon juice, 2 Tb melted butter and bake for 40 minutes in a preheated oven at 220 degrees C, mixing them halfway.
Then take the pan out of the oven, the juices would have reduced and make the cake batter ever so simply. Mix dry ingredients by hand with a whisk, add all the wet ingredients, and continue mixing until it comes together.
Pour the cake batter and smooth it on top of the warm blueberries (adjusting the paper if it has moved).
Bake for 40-45 minutes at 175 degrees C.
