In a mixing bowl stir and whip cream cheese with powdered sugar until completely soft creamy and lump free Plan to beat for a solid minute using either a spatula or hand mixer
Assemble the Sandwiches:
Spread a thick layer of cream cheese mixture onto four slices of brioche Keep the layer even but leave a tiny border to prevent leaking Layer on sliced strawberries Spoon strawberry jam over berries and gently press remaining bread slices on top so the filling sits securely between two bread layers
Prepare the Egg Mixture:
Crack eggs into a shallow bowl whisk with milk until very smooth The eggs should be fully combined with the milk and a little foamy
Dip the Sandwiches:
Take each assembled sandwich and dip both sides into the egg mixture Let the bread sit for a second in the liquid so it absorbs a bit Do not rush or skip any corners so you get a truly custardy crust
Fry the Sandwiches:
Heat butter in a large nonstick skillet over medium heat Add sandwiches making sure there is room between each for proper browning Fry for two to three minutes per side until they are golden crisp and fragrant Drain each sandwich on a paper towel to wick away any excess butter
Finish and Serve:
Transfer warm sandwiches to a cutting board Dust with more powdered sugar using a small sieve for an even snowy layer Slice diagonally for a classic cafe look Serve while hot for ultimate melty goodness
