AITA for making a dad joke to ruin my daughter’s friend party?

I have a reputation among my kids’ friends for making terrible dad jokes. <br><br>Over the weekend, my daughter invited three friends to our place for a slumber party. One of them, Sophie (10f), asked if she could bring a small cake for Emma’s birthday. I said sure, no problem. Then yesterday afternoon, I was in the backyard when I caught a whiff of smoking butter and somehow my brain decided it’d be a great idea to ruin Sophie’s cake by making my famous “dad cake”. <br><br>For the uninitiated, the “dad cake” is just a normal cake with a layer of frosting on top. Then you take a microwave-proof spatula and hold it over the frosting and heat it up until the frosting starts to melt. Then you kind of smear the melted frosting around until it looks like a hot mess.<br><br>So I took Sophie’s cake and turned it into a “dad cake”. I then walked into the kitchen to give it to her, where she was beaming with pride at her baking efforts. She looked at the cake and just looked *stunned*. I said “Hey everybody! Welcome to the party! Your friend mom just baked this cake for you using a pre-mixed cake mix and then decorating it with this magic melty frosting that’s 90% shortening! It’s so good it’ll just *melt* in your mouth!”<br><br>I think she started crying right then and took the cake back from me and didn’t give it out all evening. The other two girls also didn’t get their cakes back. Their moms kept trying to call her to see how long it’d be until she could bring it out, and Sophie just kept apologizing and saying it’d be a few minutes.<br><br>At the end of the night, I got a couple messages from the other two moms asking if everything was okay since their daughters didn’t get their cake and asking if there was anything we could do to make it up to them. I assumed Sophie had just had a bad time for some reason and was feeling awkward about it.<br><br>Then this morning, Sophie came over to drop off Emma’s untouched birthday cake. I said thanks and put it in the freezer, and then her mom asked why I preheated the oven. I asked what for, and then she just came out and said “Did you really ruin that cake with the heat gun again?” <br><br>I said yeah, what about it? She then went on to give me this super serious lecture about how when you ruin a perfectly good cake in front of a kid, you’re not being a funny dad, you’re being cruel and ruining a kid’s special moment. I said oh, so you didn’t want me to ruin the cake then? She then hit the roof and said that maybe I’m not funny, maybe I’m an asshole. <br><br>Now I feel pretty bad. Maybe I am an asshole. AITA?
