It sounds similar to something my mom made in the 1980s and 1990s called lemon delight, except it had lemon pudding and walnuts.
What my mom made only had one layer and graham cracker crust, no pecans, but I came across that one when I was looking on the internet.
But I found another on a subreddit for old recipes where you use softened vanilla ice cream, spices, sugar optional, and then freeze it, so that might be the one.
