In any Irish kitchen there is always a stale piece of soda bread left over in the bread bin, which is a great excuse to make soda bread ice cream. Roasting the bread crumbs with the brown sugar creates little crunch speckles throughout. The Baileys adds another depth of coffee and caramel flavor and a silky texture. You can leave this out if you prefer, but it really is delicious.
Preheat the oven to 350°F.
In a bowl, place the breadcrumbs and brown sugar, and mix well. Sprinkle the sugared bread crumbs onto a baking sheet, spreading them out evenly. Bake in the oven for about 10 minutes, or until the breadcrumbs are slightly darker and the sugar has melted; stir occasionally while they are baking. Let cool.
