Start by adding the cake flour, extra flour, salt, baking powder, and sugar to a medium bowl. Whisk everything together well so the baking powder spreads evenly throughout the flour. This step helps the pancake bites rise properly and stay fluffy.
In another bowl, combine the evaporated milk, lemon juice, and lemon zest. Let the mixture sit for about five minutes to slightly thicken and develop flavor. After that, whisk in the beaten egg, vanilla extract, and melted butter until smooth.
Slowly pour the wet mixture into the bowl of dry ingredients. Stir gently until just combined, but avoid overmixing because it can make the pancake bites dense. A few small lumps in the batter are perfectly fine.
Heat your ebelskiver pan or mini muffin pan over medium heat and lightly grease it with butter. Make sure the pan is warm before adding the batter so the pancake bites cook evenly. Properly greasing the pan also prevents sticking.
Fill each cavity about three-quarters full with pancake batter. Press a few blueberries gently into each bite so they stay evenly distributed while cooking. Cook until the bottoms turn lightly golden, then carefully flip and cook the other side.
Beat the softened cream cheese and butter together until smooth and fluffy. Add powdered sugar, vanilla extract, and milk, then stir until you get a pourable glaze consistency. The icing should be silky enough to drizzle over warm pancake bites.
Transfer the pancake bites onto a serving plate while still warm. Drizzle generously with cream cheese icing and add extra lemon zest if desired. Serve immediately for the best soft and fluffy texture.
