Cream the cheese, butter, and sugar together until light and fluffy.
Add a pinch of salt and the butter flavoring, and beat the mixture well.
Add the eggs, one at a time, beating thoroughly after each addition.
Stir in the flour.
Gradually add the sliced strawberries, gently folding them in after each addition.
Spoon the batter into a buttered and floured cake pan (loaf pans or mini-loaf
sizes for gift-giving), and bake the cake in a preheated 325 degrees F oven for
1 1/2 hours, until the cake begins to shrink from the sides of the pan.
Place the pans on cooling racks until cooled; turn cakes gently onto wire racks.
