Creeper Farm
A gunpowder farm that uses trapdoors on the ceiling to limit spawn height to 1.5 blocks (allowing only creepers) and cats on the platforms to scare creepers into the water streams below. Produces gunpowder at high rates for firework rockets and TNT.
Overview
The Creeper Farm is a farm build whose job is producing a steady supply of one resource with little or no manual labour; form follows function here, so the layout is dictated by how it works rather than by looks. At 17x30x17 blocks (17 wide, 30 tall and 17 deep) it is large, covering a 289-block footprint on the ground.
It is rated intermediate: nothing here is exotic, but you will need a steady supply of materials and a little patience with shaping, depth and interior detail to make it look right. Following the 22 steps below, plan for roughly 1-2 hours of focused building. This is a survival workhorse for gunpowder: once the Creeper Farm is running it keeps producing whether you are standing there or off mining elsewhere within simulation distance.
The bulk of the work is the 512 slabs that form the main body, alongside 6 different materials in total (about 792 blocks and items all told). Items move through it on hoppers, feeding the gunpowder into a collection chest without any wiring to time. There is no dedicated light block in the core list, so add torches or lanterns yourself to keep it mob-safe after dark.
Materials Needed
Gather the 512 slabs first, since it is the most-used block; the remaining 5 materials are accents and fittings used in smaller amounts. Mine roughly 10-15% extra of the main block to cover mistakes and a few decorative changes on a build this size. Make sure the hoppers that move items are crafted ahead of time, as those are the pieces most likely to be missing mid-build. Quantities are sized for the dimensions shown, so scale them up proportionally if you build a larger version.
| Material | Quantity |
|---|---|
| Trapdoor | 256 |
| Cat Spawn Egg | 8 |
| Slab | 512 |
| Hopper | 8 |
| Chest | 4 |
| Water Bucket | 4 |

Step-by-Step Overview
A high-level construction order for the Creeper Farm, from the ground up. Each phase below covers several of the 22 in-game steps.
- 1Pick the spot the Creeper Farm needs — a valid spawning location for the mobs it targets — then clear it and build the hopper-and-chest collection layer first so no drops are ever lost.
- 2Raise the body of the Creeper Farm to its full 17x30x17, working from the collection floor upward so each layer sits on the last.
- 3Set up the working part of the Creeper Farm — a charged or dark platform where only creepers fit — which is what actually produces the gunpowder.
- 4Light or darken precisely: the spawn space for the Creeper Farm must stay at the light level the target mobs need, while every surrounding surface is lit so nothing else spawns and steals the cap.
- 5Build the AFK or harvest spot, run the Creeper Farm for a full cycle, and time the gunpowder output before you rely on it day to day.
Build Tips
- 1Trapdoors on the ceiling trick the game into thinking the space is 1.5 blocks tall, preventing spiders and endermen.
- 2Cats scare creepers within 6 blocks, pushing them toward water collection channels.
- 3Build at Y=200+ in the sky to minimize nearby cave spawns stealing mob cap.
- 4Fall damage or campfire kill the creepers at the bottom.
Tips & Variations
The Creeper Farm has no light block in its core list, so add torches, lanterns or sea lanterns yourself: light every interior tile and the ground around it so nothing spawns on or beside the build overnight.
To resize the Creeper Farm, keep its 17x17 proportions and grow both axes together; stretching one direction alone tends to make it look thin. A half-size or double-size version both work as long as you scale the 792-block material list to match.
For a different look, swap the slab in the Creeper Farm for another palette that fits your biome: the shape stays identical, but the colour and texture of the main block changes the whole feel of it.
The most common mistake on the Creeper Farm is a leak in the collection path; trace it and confirm every hopper, water flow or drop chute actually feeds the chest before you leave it producing gunpowder unattended.
Frequently Asked Questions
How hard is the Creeper Farm build?
It is rated intermediate: nothing here is exotic, but you will need a steady supply of materials and a little patience with shaping, depth and interior detail to make it look right. It is laid out in 22 steps and takes roughly 1-2 hours of focused building to finish.
What blocks do you need for the Creeper Farm?
The main block is slab (around 512), and the full list runs to 6 materials — mostly slab, trapdoor and cat spawn egg. Altogether that is roughly 792 blocks and items; the complete table with exact counts is above. Item transport uses hoppers.
How big is the Creeper Farm?
It measures 17x30x17 blocks — 17 wide, 30 tall and 17 deep — which is large and takes up a 289-block footprint. You can shrink or enlarge it by keeping those proportions.
Is the Creeper Farm survival-friendly?
This is a survival workhorse for gunpowder: once the Creeper Farm is running it keeps producing whether you are standing there or off mining elsewhere within simulation distance.
Does the Creeper Farm work on its own once built?
Largely, yes — after setup the Creeper Farm keeps producing gunpowder as long as you are within simulation range; just check the collection chest now and then and top up anything it consumes.
What makes the Creeper Farm different from similar builds?
It is best understood through its focus on creeper, gunpowder and firework. Those traits drive the material list and layout described above, and are what set this farm build apart from a generic gunpowder build.
