Oatmeal streusel bake could be defined as a baked porridge, meaning baked in the oven, with a streusel topping. This version for the Gluten-Free Menu, is gluten free meaning with a rice flour-based streusel and certified gluten-free oats for the base.
The technique of streusel — a crunchy topping of flour, butter, and sugar — a crumbly mixture of sugar, fat, and flour in the ratio of 1:1:2, has origins in Central European cuisine (Germany/Poland).
In the United States, the idea of “baked oatmeal” (oatmeal baked instead of boiled in a pot) has become popular in recent decades as a more “comforting” and “baked” alternative to the classic oatmeal porridge.
The streusel topping on an oatmeal base makes the dish similar to a fruit “crisp” or “crumble”, but with the more solid and single-serving texture of baked oats.
N.B. The terms crisp and crumble refer to desserts made with a topping of streusel (similar to shortcrust pastry) of brown sugar sometimes containing (old-fashioned) oats.
The topping can include chopped nuts, seeds, or spices like cinnamon, ginger, nutmeg, for a more “autumnal” version.

FAQ (Questions and Answers)
What is the difference between streusel and crumble?
The main difference between streusel and crumble lies in their function and composition.
• Streusel: of German origin, it is a topping often used for yeast-raised baked goods (like cakes or muffins) before baking.
• Crumble: Anglo-Saxon, typical of fruit pies (apple crumble, berry crumble) where the fruit is underneath and the crumble on top.
Both are made with flour, butter, and sugar, but:
• Streusel: often finer and more sandy, sometimes with spices or nuts.
• Crumble: has a coarser and crispier texture, may contain oats or nuts.
• Streusel: thinner, lighter, crumbly.
• Crumble: more rustic and crunchy.
In summary: streusel is a decorative topping for cakes, while crumble is a dessert in its own right with a fruit base and crunchy topping.
