What other desserts had McDonald's introduced this year?

The new McFlurry flavor is the latest dessert that McDonald's has introduced this year as it continues to test new products.

In March, the chain debuted a Strawberry Shortcake McFlurry that temporarily joined its other classic McFlurry flavors, like Oreo and M&M.
