Riddonkulous

I rest upon a plate beside a cup of tea A little golden treat for you and me I crumble when you bite and break With every mouthful, joy I make Sometimes I am sweet with chocolate inside Sometimes with butter, my flavors hide I come in many shapes and sizes too From crunchy and crisp to soft right through Dipped in milk, I slowly melt away A perfect companion at the end of the day From kitchens and bakeries, I often appear A simple little snack that brings us cheer What am I, so tasty and small A crunchy delight loved by one and all
