For decoration, open 1-2 rice krispies square and crunch it together and press it into the heart cookie cutter. You can just cut the rice krispies square with cookie cutter, but I find them to be too crumbly unlike when you make your own rice krispies cake! You can then paint it with liquid food color OR you can mix it in while crunching the rice krispies together (use gloves if you don’t want to stain your hands! – of course the food color is washable tho ?
Insert a toothpick on the bottom of the heart and press this heart into the center of the cake as shown.
For the family birds, I use fondant, colored in blue and pink (presenting my husband and my sons, are blue birds and me with the pink bird). For each bird, I insert spaghetti on them and press them on the cake and to the heart. The ones for the heart, I also dab teeny tiny buttercream so they would stick to the heart.
