The Mini Bundt Cakes are baked fresh daily and come in three varieties: Cinnamon Coffee Cake, Lemon, and Double Chocolate.
According to the Palm Beach Post, the test market includes McDonald's restaurants in Palm Beach County and the Treasure Coast.
The Bundt Cakes are being sold with a choice of any two for $1.99. They're available all day and clock in at 160 to 180 calories a piece.
Some of you might remember that McDonald's also tested Petite Pastries as a possible McCafe beverage accompaniment earlier this year in March.
