Bring the butter to room temperature. When the butter has softened, mix in the sugar.
Slice the sliced sandwich bread down its side (to make two thin slices), then cut in a cross-shaped pattern to make 4 squares.
Place the bread in a heat-resistant plate and microwave for 2 minutes.
When the moisture has evaporated and the bread has hardened, flip them over, and microwave for another 1 1/2 minutes.
When the moisture has evaporated and they are crispy, spread the sugar butter onto the toasts.
Toast in the toaster oven for 1 1/2 minutes, once the butter and sugar has melted and both sides are golden brown, they are done.
Story Behind this Recipe
Rusks are so expensive when you buy them at bakery stores. I wanted to make them easily and in an inexpensive way, so I came up with my version by referencing a variety of recipes.
I use 5-slice loaf (thickly sliced) bread for these rusks, split them in half down its side, and microwave at 600 W. Adjust the microwaving time according to the thickness of the bread, and model of microwave oven. The moisture in the bread might not evaporate completely or on the other hand, it might burn on you, so keep an eye on them. I think it will also be fun, to cut out the bread into shapes with your child.
