Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
For every black & white cookie that Elsa makes, she has to make the batter, bake the cookies for 15 minutes and then allow to cool.  She then has to dip the cookies in white icing and allow the icing to harden for 30 minutes. Then she has to re-dip them in chocolate icing and allowed to harden for an additional 30 minutes.  If it takes her 2 hours to make the cookies from start to finish, how long does it take to make the dough and cool the cookies before she can start dipping them?

### Response:
 Inachukua dakika 15 kwa kupika, dakika 30 kwa icing nyeupe itie nguvu na dakika 30 kwa icing ya chokoleti itie nguvu, hivyo ni dakika 15+30+30 = <<15+30+30=75>>75
Kuna dakika 60 katika saa 1 na inamchukua masaa 2 kutengeneza biskuti, hivyo ni 60*2 = <<60*2=120>>120 dakika
Anatumia dakika 75 kupika na kuziruhusu icing itie nguvu na inamchukua dakika 120 kutengeneza biskuti kutoka mwanzo hadi mwisho, hivyo inamchukua dakika 120-75 = <<120-75=45>>45 kutengeneza unga na kuzipoa biskuti
