* Weaponized by The Breadmaster, a villain on ''WesternAnimation/TheTick'', first as bread bombs that can encase entire buildings when activated, and finally, as a giant souffle that will devour the whole city. Luckily, Tick manages to destroy it by generating a sonic boom while getting shot out of the Human Bullet's cannon.

* In ''WesternAnimation/HeyArnold'', the kids of the city work on the world's biggest pizza puff in a bid to break a world record. All seems well until Sid reveals that he misunderstood "tsp" in the recipe. Instead of "teaspoons", he read it as "ten square pounds"! The resulting explosion of dough takes a good deal of the next day to wash off the streets. This incident provides the page image.

* ''WesternAnimation/TheNewAdventuresOfWinnieThePooh'': When Rabbit has Pooh bake a cake for a party, Pooh completely misunderstands every single one of the instructions and eventually Rabbit gets tired of him taking too long and throws the batter into the oven, which then floods Rabbit's house with batter a few seconds later. The recipe didn't even have any leavening agents in it so how that even happened is a mystery.

In comedy shows, yeast tends to be treated as far more volatile and powerful than it actually is. A [[LethalChef less than stellar baker]] will add more yeast to a recipe than it needs, often many times more, and the dough reacts explosively. If you're lucky, all that you get is a mess in the kitchen, or a pizza that nearly fills the oven as it bakes. However, it's just as common to see the dough explode all over the kitchen or, in extreme cases, come to life as a doughy BlobMonster. Occasionally, baking powder and baking soda, also known for their leavening properties, can cause much the same problems.

* There's a ''WesternAnimation/GoofTroop'' story with this happening in Pete's kitchen, then whole house: When instructed to add 3 drops of ultra-concentrated yeast five minutes before the cake is done, Pete just poured the whole bottle in at the start and went for the TV.

* ''VideoGame/Destiny2'': A lore snippet for one of The Dawning events has happen after Saint-14 messes with the recipe for a treat for several Eliksni children. Notably, this wasn't due to yeast, but rather Saint massively increasing the temperature of the oven. Apparently, he had to block off the Kellsdough with a ''Ward of Dawn''.

* In one episode of ''WesternAnimation/GoofTroop'', Pete was making bread dough, and when his back was turned, it started to rise out of control. When Peg asked him how much yeast he put in, he said he followed the recipe which said to put in a ''pint'', only to double check it and see that it actually said ''pinch''. Upon seeing the growing blob of dough, Pete tried to pass it off that he made enough to last a few months...just before it exploded and covered Pete and the kitchen.

* In ''The Duchess Bakes a Cake'' by Virginia Kahl, a duchess at a castle gets bored with her usual daily routine and decides that she will bake "a lovely light luscious delectable cake" for the entire castle. Wanting the cake to be as light and fluffy as possible, she puts in an excess amount of yeast before baking it. This causes the cake to expand out of control, burst out of the kitchen, and tower over the castle with with the duchess on top of it. The king, queen, and their subjects work themselves silly trying to figure out how to get the duchess back down until they realize they can all just ''eat'' the cake, and so that's what everyone does, resulting in a mass TemporaryBulkChange but getting the duchess safely back down to the ground.
