For the same building in Cookie Clicker Classic, see Grandma (Cookie Clicker Classic).

The grandma is the main antagonist of Cookie Clicker Classic and the 1.0 Update, and the second building you can purchase with an initial cost of 100 cookies. She produces cookies at a base rate of 1 CpS.

Unlike the Cursor and Farm, grandmas progress with later buildings very well with the grandma type upgrades, most of which double its efficiency but require 15 or more of a superior building to purchase, and sometimes can be quite expensive, up to 3.55 sextillion cookies for Binary grandmas. After all upgrades, each grandma has a CpS of 1.172 billion cookies per second herself, not counting the bonuses from One mind, Communal Brainsweep, and Elder Pact.

Once you have unlocked 7 grandmas, you unlock the Bingo Center/Research Facility, which (as of 1.036) is currently the only upgrade to make a building four times as efficient, although its price of 1 quadrillion cookies means it'll be a while until it's worth the cost. This will unlock a new upgrade after 30 minutes (research only starting once the last item researched is purchased), including five multiplier upgrades, one upgrade to double grandma efficiency, and three upgrades to greatly increase grandma output but start the Grandmapocalypse.

In theory, fully upgraded grandmas are the most efficient building a player can buy because they have a CpS based on the number of grandmas purchased. That is grandma's CpS rate increases as a square where other CpS rates increase linearly. However, the crossover point where grandmas outperform the best other building, the Javascript Console, requires purchasing so many grandmas (64630) that it is impossible to even via cheating since the price would be much higher than JavaScript (which Cookie Clicker is written in) can store. (The price has 3925 digits!)

The Bingo Center/Research Facility can also unlock new upgrades for grandmas. Although these upgrades can make grandmas more powerful, they would unlock the Grandmapocalypse as well. The following is a list of all upgrades for Grandma, unlocked in the Bingo Center/Research Facility. Once the Bingo Center is purchased, the first research project will be completed 30 minutes later. Once a research project is completed, research is halted until the resulting upgrade is purchased, which starts the 30-minute timer for the next project.

Changes During GrandmapocalypseEdit

Main article: Grandmapocalypse

Background ChangesEdit

Changes from one stage to another can be obtained by the One Mind, Communal Brainsweep and Elder Pact upgrade. Once the Grandmatriarchs are appeased, the background will change back to normal, as well as the store icon changing back to the regular grandma, until the Elder Pledge runs out or if you revoke the Elder Covenant.

Store Icon ChangesEdit

Since version 1.0393, the store icon for grandmas will change from the regular version to different ones, depending on the state of the Grandmapocalypse.


  • The outfit worn by bunny grandmas during Easter may be a reference to the 2001 film Donnie Darko.
  • The achievement "The old never bothered me anyway" is a reference to a line from "Let it go", the Disney movie "Frozen" theme song.
  • The appearance of an Altered Grandma resembles that of an angered Grandmatriarch during the Grandmapocalypse.
    • To further support this, the research/bingo center upgrade would be available at around the time the player buys the Altered Grandma.
