A book I read as a teen: maze that transports you to the past, girl chasing baby carriage

Question

I read this book 21 years ago. The main points I remember from the book are a maze that transports you to the past: in the present the maze is chalk I think, and in the past it's a full hedge maze. Also there was a baby carriage that travels being chased by a girl, and an old woman who offered candy but the candy was all melted together. There are a couple of other books I can't remember but I'll only do one at a time.

Answer 1

This sounds like the 1989 novel Mazemaker by Catherine Dexter.

Someone else has asked a similar question here, which is how I found the book. Quoting from the reviews here (emphasis mine):

Winnie and her friend Harry have only the city schoolyard to hang out in, with its broken glass and graffiti-covered walls. But one day a cat they've found runs through a spray-painted maze they discover--and disappears. Winnie, too, runs the maze, which transports her through time to 1889, and delivers her into the hands of a deranged woman, Mrs. Minot, who is determined to use the maze's power for herself. Winnie learns of others who have disappeared; if she is to find her own way home, she must prevent Mrs. Minot from altering time. While not as chilling as Dexter's Oracle Doll , Mazemaker is still riveting, with likable characters in Winnie, Harry and Lily. The ending, if plausible, is a little too easy, but overall the book is a worthwhile read. Ages 10-14.

When Winnie finds a large, intricate maze spray-painted on a deserted playground, she can't resist trying to negotiate it. As she triumphantly reaches the center, she finds herself transported 100 years into the past, but on the same spot--in the center of an overgrown but still discernible hedge maze.
