This easy vegan pineapple sheet cake tastes like a tropical vacation and mixed straight in the pan so you don’t have to dirty up an extra bowl or mixer!

Sometimes (or maybe all the time), we just need cake fast. In these situations, I want something easy that uses up ingredients I likely have in my pantry and dirties up minimal dishes. For this, my go to cake is a wacky cake (sometimes call depression cakes), which are made without the usual eggs, milk, and butter that cakes often call for. They are also intended to be baked and served right in the same pan. 

I decided to jazz the usual wacky cake recipe up by adding some island vibes to the mix and incorporating pineapple. The results were wonderful and I’ll definitely be coming back to this recipe time and time again.

Hey, I would love to try this recipe! Any idea whether the pineapple extract can be substituted for real pineapple instead? And if so, whether you know the amount :). Thank you for a great recipe 😋🍍🍍

    Hi, Veera! I haven’t tested this recipe with actual pineapple, so I can’t be sure. Because it is such a small amount of liquid, I wouldn’t try to use real pineapple there or it might lack that pineapple flavor. Alternatively, if you use too much real pineapple juice, it’ll completely change the consistency of the cake and/or buttercream. I’d recommend sticking to the extract on this one if possible! I do have a pineapple coffee cake recipe coming soon, so keep an eye out for that. It uses real pineapples. 🙂
