Obleas are a beloved Colombian street sweet that consists of large, paper-thin wafer discs sandwiched together with arequipe (dulce de leche). These crispy, delicate treats are a perfect example of how simple ingredients can create something extraordinarily delicious. The wafers themselves are light and neutral in flavor, providing the perfect vessel for the rich, caramel-like arequipe filling.

While the exact origins of obleas in Colombia aren't well-documented, they're believed to have European roots, particularly from religious wafer-making traditions. Over time, they evolved into a popular street food in Colombia, where vendors with their distinctive oblea carts have become a common sight in parks, plazas, and street corners.

The beauty of obleas lies in their simplicity and customization. The basic version starts with two thin, crispy wafers with a generous spread of arequipe between them. However, Colombians have developed numerous creative variations. Popular toppings include fresh white cheese (which adds a delightful salty contrast), fruit jams, condensed milk, sprinkles, and even multiple layers of different sweet spreads. Some vendors have become known for their signature combinations, creating what locals call "obleas con todo" (obleas with everything).

In Colombia, obleas are typically enjoyed as an afternoon snack or dessert. Street vendors often assemble them fresh to order, ensuring the wafers maintain their crispiness. They're particularly popular during festivals and celebrations, and you'll often find long lines at the most popular oblea stands. The treat is meant to be eaten immediately, as the wafers can become soft if left too long with the filling.

From a nutritional standpoint, obleas should be considered an occasional treat rather than a daily indulgence. The wafers themselves are relatively low in calories, but the fillings, particularly arequipe and condensed milk, are high in sugar. A typical oblea with arequipe can contain anywhere from 200-300 calories, depending on the amount of filling and additional toppings. Those with dental concerns should be mindful of the sticky nature of the arequipe filling. Additionally, the wafers typically contain wheat flour, so they're not suitable for those with gluten sensitivities.
