During the week prior to laying, sexually mature females of ''B. plumifrons'' were observed presenting herself to the male. The female would position herself about {{convert|0.5|m|abbr=on}} from the male, lowering her forebody to the sand and raising her pelvic region and tail.  Females lay five to fifteen [[Egg (biology)|eggs]] at a time in warm, damp [[sand]] or [[soil]].  One mother lizard in [[captivity]] actually was observed to start digging holes (sometimes referred to as nests) in the soil six months prior to ovipositing, well ahead of the breeding season.{{sfnp|Banks|1983}} The eggs hatch after eight to ten weeks, at which point they emerge as fully independent lizards, although averaging only {{convert|43|mm|abbr=on}} SVL (Snout-to-Vent Length) and weighing only about {{convert|2|g}}.{{sfnp|Banks|1983}} The juvenile males would start to develop the large crests which are characteristic of the male ''B. plumifrons'' after six month or up to more than one year, depending on the body conditions of the juveniles.

Female ''B. plumifrons'' start "showing" (become visibly plump) one to two weeks post-fertilization. During the third week of gestation, females will begin to search for a site to burrow or lay approximately 14–17 eggs. Typically, the size and quantity of eggs will vary depending on the lifestyle and physical characteristics of the mother (i.e. age, health, and size). It is common for plumed basilisk females to lay multiple clutches within a given season and this event will occur up to four or five times during a given breeding season. Hatching of eggs occurs over a one to two day period after a gestation and incubation period of eight to ten weeks.{{sfnp|Pawley|1972}}{{sfnp|Laerm|1974}}
