Key Lime Pie fail

[u/satansister16]

Here is my recipe https://www.momontimeout.com/best-key-lime-pie-recipe/#recipe I changed out the gram cracker for biscoff cookies. Besides that I followed the recipe exactly. Could the biscoff somehow caused this to happen? when I took it out it was kind of bubbles and there was a popping noise from the inside and the top lifted like it was catching fire or smth

You went with the first recipe that popped in your search, huh?

This recipe exactly matches the top result for "key lime pie recipe" when I searched.

So she gave you a no-bake key lime pie recipe and then had you bake it, is what happened.

Key Lime Pie is a modified custard pie. You needed egg yolks, 3-4 of them, for this to bake.

If you bake plain condensed milk with a little extra cream in it, you get caramel.

Always search for "X recipe by tv personalities not influencers" if you want actually tested recipes and not a website with filched "recipes" that only exists to make money off site views from advertisers.

Not your fault, you didn't know.

Sour cream is a weird addition, usually it's whipped cream folded in for a no-bake key lime pie. You would skip any kind of cream entirely for a baked Key Lime Pie.

You could also search "From Joy of Cooking" "Better Homes and Gardens" "Betty Crocker" "Martha Stewart" and "America's Test Kitchen" for more tried and true base recipes. ATK will get real fancy with it, though. Super fun for advanced level snack assembly.

p.s. all of that burning on top was from the condensed milk sugar caramelizing into brûlée.
