Sorry for the bad English, I'm not a native speaker.

For context: me (15 F) and my best friend (14 F), who came to my house today, decided to bake a cake, we went shopping for the ingredients and I payed for them, then we went home and started baking, we spent a good 45 minutes or more doing all the preparations and when it was time to put the cake in the oven I asked her to put it in for me because I was scared to burn myself, she took the cake put though that the cake pan wasn't closed, so she decided to close it (open it) and as soon as she told me that I tried to stop her for doing it but I was too late and she did it anyway so all the cake mixture ended up on the opened oven, on the ground and on her jeans and shoes, I was so irritated and frustrated that I almost cried, she looked at me dumbfounded like she didn't know that would happened, I obviously got mad and told her to move so I could clean and she kept saying she was sorry but I keep thinking that if she used her brain that wouldn't happened. She had to leave after that happened for other reasons and I had to clean all my kitchen floor, oven, sink with all the things we used all by myself, the only thing she did before leaving was cleaning herself and leaving me 10€ that was obviously not enough for all the ingredients we used, but I didn't want her money anyway. Now, technically she has to come to my house in some days for the weekend because her parents are going on a trip, but I don't want her in my house anymore, I already told all the story to my mom and she suggested to forgive her and that we can still bake the cake tomorrow, but that's not the point, she could have used her brain and that wouldn't happen. So AITAH?
