National Apple Betty Day is celebrated on October 5 in the United States and Portugal, honoring a traditional dessert known for its delicious combination of baked apples, oats, and cinnamon. This dessert, often referred to as Brown Betty, has roots that trace back to the colonial period and is similar to apple crisps and cobblers. The dish is typically made with ingredients like lemon juice, bread, brown sugar, butter, and Granny Smith apples, and is often served with whipped cream or ice cream. The sweet aroma of an Apple Betty is said to fill homes with warmth during the autumn season, making it a perfect treat as tart apples become available. Celebrating this day often involves baking and enjoying this comforting dessert, which is both simple to make and beloved by fans of apple pie.
