I like to make lemon dessert... it is layered

I use digestive biscuits and a mix of lemon juice, evaporated and condensed milk. I mix it in the blended until the consistence gets thicker. I then place a layer of digestive cookies on the bottom of a rectangular container, I then pour some of my mix... I sometimes add some grated dark chocolate and a few pecans. Then I proceed to create the next cookie layer, pour the mix... do the same over and over until I am out of cookies and mix. I get 4 glorious layers in total
Now I just have to figure out what digestive biscuits are

. That sounds yummy!
The only layered pudding desserts I've made are trifles. I haven't made one in a while, since I don't have a crowd here these days, but I usually would make a white one and a chocolate one. The 'white' one would consist of angel food or pound cake, torn up into pieces, vanilla pudding (or another variety if you prefer, such as butterscotch, banana, pistachio, etc.), fruit such as a mix of mandarin oranges, blueberries, strawberries, etc., whichever you prefer, and whipped cream or cool whip. The recipe is made in a trifle (usually footed) bowl, and can be refrigerated until it's time to serve. Each layer is piled on top of one another, starting with the cake, then pudding, whipped cream, fruit, etc., and ending with fresh fruit on top.
The chocolate would be similar, but could be make with devil's food cake or brownies, again, torn or cut into pieces, chocolate pudding (or to lighten it up, a different flavor), whipped cream, fruit or small pieces of cut up candy bars.
If you'd like to lighten it up a bit, you could use angel food cake, vanilla yogurt, whipped cream (or skip the cream), and fresh fruit.
