From looking at this cake, you'd think it's an unsuspecting pineapple upside down cake, right? But it's more than that. Let me be clear. It's more flavorful than that but don't think there's a ton of work involved in baking this stunning dessert. You know I am all about ease, which includes easy dessert ideas, sis. And this key lime pineapple upside cake is just that. It's my new favorite thing because it combines two of my most loved treats (key lime pie and pineapple upside down cake) into one beautiful flavor bomb baked up in a cute little package. Let's get into it.
If you know me, you know I am forever putting a little twist on things and this sweet dessert idea is no different. A healthy dose of key lime juice and zest provides the perfect hit of tartness to balance out what would otherwise be an exceedingly sweet cake. Pineapple is naturally really sweet and between the crushed pineapple, pineapple juice, and brown sugar, there's a LOT of sweetness going on here. All of this talk about pineapple reminds me, to recommend you also try this beauty. It's a cross between pineapple upside down and rum cake and it's the bomb.com periodt okkurrrrrt?! Trust me, it's one of the most popular recipes here on the blog for a very good reason.
I like to use brown sugar in my pineapple upside down cakes for a deeper, caramel-esque flavor throughout. It plays so well with the pineapple but you should note that the cake will not turn out the pale yellow color we have come to expect with box mixes. And that's just fine. We're making soulful pineapple upside down cakes only, OK? Normally, I'd use pineapple rings when baking pineapple upside down cake but used crushed pineapple for this key lime loaf cake and the outcome ensures you get pineapple in every single bite! Now, key lime pineapple upside down cake is best enjoyed warm and it reheats well. But be sure to store it in the fridge...if you make it to the point of having any leftovers, that is.
Tips for Pineapple Upside Down Cake
- In this recipe, you can use either dark or light brown sugar. Dark brown sugar will give a deeper caramel-like molasses flavor and the color of the cake will be darker.
- You can also use pineapple rings in this recipe or pineapple chunks instead of the crushed pineapple. Pineapple chunks would be my last choice because of their thickness. I recommend cutting them thinner if you want to use chunks.
- Be sure to bake this cake on the middle rack. You never want to burn the bottom of a cake but especially don't want burned pineapple upside down cake because the bottom is really the top! So don't bake it on the bottom rack.
How to Remove Upside Down Cake From Pan
Wondering how to remove this pineapple upside down cake from the pan? Don't be nervous. It's actually quite easy! Here are a few tips for a beautiful result every time with no sticking.
- Be sure to use a non-stick pan. Pineapple upside down cake is quite buttery so sticking is not typically a problem but you don't want to be disappointed, right?
- Let the cake rest for about 10 minutes before flipping it over.
- Run a butter knife around the edges of the cake to release any sticky bits on the sides.
- Flip the upside down cake over by placing a plate or platter on top then gently inverting the pan onto it.
- Let the pan sit on top of the cake for a couple of minutes so all the buttery, brown sugary, pineapple-y goodness seeps down into it.
- Tap the pan a couple of times then gently pull it away.
