Preheat oven to 350 degrees F.

Into a large bowl, sift together the flour and sugar.

In a small bowl, mix the egg whites and butter together. Slowly add to dry ingredients. Mix so all lumps are removed.

Using a silicone mat, lay out a stencil (whatever shape you desire), and spread batter with a pallet knife so the batter is the same thickness as the stencil.

Place in the freezer for 3 to 4 minutes and remove. Run a knife around the inside edge of the stencil, making sure not to alter the shape of the biscuit.

Bake on a sheet pan for 4 to 6 minutes until lightly brown around the edges.

Remove from the sheet pan with a metal spatula, as biscuit will continue to bake on hot pan. Serve.
