Tart Top is one of the four new Battle Stages in Mario Kart DS. The course itself is very much related to Cookie Land from Mario Kart: Double Dash!!; the theme is pastries and candy (such as heart-shaped jellies and cream puffs).
In the center of the stage, there is a giant cream mountain. The only Item Boxes are in the air, making it where they are only accessible after going off a Dash Panel that goes up the cream mountain. One obstacle in this course is related to the Blooper, but not as powerful. When hitting a cream puff, icing will splat on the screen.
