Preheat oven to 325°F (160°C).

Sift together cake flour, salt, and cinnamon in a bowl.

In a separate bowl, beat eggs until light and fluffy.

Gradually beat in brown sugar and evaporated milk into the egg mixture.

Add the flour mixture to the egg mixture in three additions, beating until smooth after each addition.

Fold in the cut gumdrops and chopped nuts.

Spread the batter evenly into a greased baking pan.

Bake for 35 minutes, or until a toothpick inserted into the center comes out clean.

Let cool completely before cutting into 4 x 1-inch bars.

Spread frosting on top of each bar.

Decorate with sliced gumdrops.
