Instructions

Preheat oven to 350 F.

Bottom layer

Mix flour, 1/4 cup brown sugar, butter, egg yolks, lime zest, baking powder, and salt until crumbly and mealy.

Press into the bottom of an ungreased 4 x 8 loaf pan. Set aside.

Top layer

Beat egg whites until frothy.

Add the brown sugar and lime juice a bit at a time until stiff (should look like a meringue).

Spread evenly on top of the bottom layer.

Sprinkle the sliced almonds on top evenly.

Bake in a hot oven for about 30 minutes or until the meringue is set and lightly browned.

Allow to cool completely. Take a sharp wet knife and run along the pan edge to loosen the meringue, cut into squares.

Serve at room temperature.
