Ingredients: overnight toast to taste, butter (softened) to taste, caster sugar to taste
Start production:

(1) Cut the overnight toast off the four sides and cut into slices or strips of equal shape. (Figure 1)
(2) Bake in the oven at 150°C for 10 minutes. (Figure 2)
(3) Remove and thinly coat the surface with softened butter, applying all six sides. (Figure 3)
(4) Sprinkle evenly with caster sugar and re-bake in the oven until the surface is golden brown. If using a baking dish, remember to turn the dough halfway through (it takes about 30 minutes).
