For the first step (and to save time), preheat the oven to 350F (180C). Now, you'll get your baking sheet ready with parchment paper and set aside.
Take a small bowl and then toss the berries with the sugar. By berries, I mean blueberries if you prefer, or strawberries, or even blackberries if you’re into them. Leave the berries and the banana slices with the sugar in the bowl and set the bowl aside to macerate while you work on the toast box.
A serrated or bread knife will work best for this next step. But if you don't have one, a vegetable or puntilla knife will work. Just be careful not to squish the bread too much. If the knife's sharp enough, cutting the bread won’t be hard. If you don’t want to risk it, hit up a friend and get yourself a bread knife!
Using the knife, start cutting a square from the crustless side of the bread. Make sure to leave at least a ½-inch border on all 4 sides and at the bottom side. These will be your beautiful walls.
Now take the squared crustless bread and cut small bite-sized cubes. These smaller cubes will also go in the oven to get crusty.
Spread the pieces and the hollowed out box on a prepared baking sheet and brush them on all sides with a melted butter and honey mixture (1:1 ratio) so they’re evenly covered. Brush the inner walls of your toast box with only butter. You can use a cooking brush for this or the back of a spoon.
Put them inside the oven once it's reached the needed temperature. Open the oven occasionally and turn all the cubes so they brown evenly as well. Do this until the small cubes are crisp and golden. It’ll take about 15 minutes. Afterward, remove the bread cubes and continue baking the toast box until crisp. That should take 10 more minutes.
Once you take the toast box out of the oven, brush the inner walls with sweetened condensed milk. Your kitchen must be full of a freshly baked aroma by now!
Now put the crusty pieces of bread back into the toast box and drizzle with 2 tablespoons of honey (If you want to add more, go ahead; it’ll be our little secret ;) ).
Top the toast with the pieces of sugared fruit, and add 1 scoop of your favorite ice cream flavor and whipped cream. Garnish it with cookies, candies, and/or nuts as desired. Drizzle the magnificent structure of sweetness with a final tablespoon of honey or chocolate sauce and serve right away with forks and knives. This dessert is meant to be served hot.
