No-Bake Mini Heart Cakes

Have ready 2-in. and/or 2 1/2-in. heart-shape metal cookie cutters. Using a long, sharp knife, trim rounded hump off poundcake so top is flat. Trim crust off sides. Slice cake horizontally in half. Cut hearts from each half. Put hearts 1 1/2 in. apart on a wire rack set on wax paper to catch drips. Icing: Stir ingredients, except food color, in a bowl until smooth and as thin as maple syrup. Divide between 2 bowls; cover 1 bowl with plastic wrap. Tint icing in other bowl pink. Spoon pink icing over half the cakes, completely covering tops and sides. Stir drips on wax paper into icing in bowl; cover airtight. Let icing set 30 minutes. Meanwhile repeat with white icing on rest of cakes. Thin remaining pink and white icings with a little water as needed; give cakes a second coat. Let set at least 1 hour. To decorate: With decorating icing, pipe designs and words on cakes as shown, or create your own designs. Add red sugar and candy hearts.
