Selection of candy
Make the icing
Put the icing sugar, egg whites (from a carton is easiest), lemon juice and vanilla in a mixing bowl and start beating on the lowest setting until ingredients combine.
Increase speed to maximum and beat until the icing holds firm, stiff peaks.
Transfer the icing into a piping bag (or ziplock bag). Keep any icing you are not using immediately covered by placing plastic wrap directly on the icing as it dries very quickly.
Cut the Pop Tarts
You will need to cut your pop tarts with a serrated knife to construct your house. Place them on a silicone mat so that they don't move around. Be careful and use a sawing motion as the poptart can crumble at the edges. Follow my diagram below to cut the house panels.
Assemble your house
Cut a tiny hole in the icing bag and pipe icing down the sides of the front panel of the house. Pipe icing along the sides of the side panel and stick to the front panel, using a tin or jar to keep it in place until it dries. Add the second side panel, again keeping it supported on the other side.
Add icing along the top edges of the side panel and position the second front panel on top – the tension between sides and front will keep the pieces in place. I
Once the bottom of the house is sturdy you can the roof panels on top, using icing to stick the whole house together.
