I saw [a sticker set](http://www.line-tatsujin.com/detail/a112839.html) being
used on a popular social platform the other day that I found very interesting.
They were pictures of food items, sweets mostly, and had words next to them
that seemed to be portmanteaus mixing Japanese phrases with the names of the
food. I was able to identify some:

  * picture: _a candied apple_   
caption: _おかえリンゴ_ .  
my guess: _a portmanteau of おかえり and りんご_

  * picture: _a piece of 羊羹_  
caption: _おはようかん_.  
my guess: _a portmanteau of おはよう and ようかん_

  * picture: _a piece of lemon meringue_  
caption: _おつかレモン_  
my guess: _a portmanteau of おつかれ and レモン_

  * picture: _some mochi_  
caption: _餅ろん_  
my guess: _a portmanteau of もち and もちろん_

Pretty straightforward so far, but then there is this one:

![a piece of cake, captioned ケーキがいいね](https://i.stack.imgur.com/UXFP1.png)

> picture: _a piece of cake_  
>  caption: ケーキがいいね

After consulting a dictionary, I thought maybe it's a pun on 景気がいい, meaning,
"the situation is good," or "business is good." I'm not very confident in this
analysis, since I personally can't recall having come across this expression
myself.

Sticking heads together with friends didn't turn up anything either, and the
one Japanese person we were able to ask about this replied, "Well, cake _is_
good." I don't think she understood our issue all that well.

What kind of pun could this be?

question
meaning puns
What's the meaning of this pastry pun?
I would say it is a pun on 景気が良い like you guessed.

Informally the long vowel mark ー is often used in place of the sound イ, for
instance けいこ→けーこ.

The expression 景気がいい is used quite a lot. References:

  * 新聞やニュースで、よく「景気がいい、景気が悪い」という言葉が使われます <http://diamond.jp/articles/-/17436>
  * 景気がいい時は、お給料が上がりやすかったりモノが売れやすかったりというイメージがありますよね。 <http://www.k-zai.net/ebasic/020_economy.html>

Do all stickers use extremely simple words that any 5-year old would
understand? If yes, then 景気 would stand out as a more difficult word and
Earthliŋ's suggestion of 天気がいい would apply better, I guess.
