This Easy Key Lime Cake with a Graham Crumb Swirl is an fun and delicious take on key lime pie!

Previously on Sweet Peas & Saffron: key lime.

There were cupcakes…and macaroons…and sandwich cookies.

Then there was white chocolate, and cream cheese, and even pistachios.

And now that you’re all caught up, here is key lime in its latest incarnation: easy key lime cake.  With crinkly key lime glaze.  And a graham cracker crumb ‘swirl’.

I guess it’s no surprise that key limes are back on the menu….I am totally and unapologetically a huge key lime addict, especially when graham crackers are involved in one way or another.

There’s just something about that combination of light citrussy key lime with the deeper cinnamon and honey flavors of the graham crackers…I’m bonkers for it!

I haven’t made cake since…November.  Gosh, is that a travesty or what?

Since the cake eaters of the household is really just Ben and I, and Ben doesn’t have much of a sweet tooth, cakes are just not all that practical for us.  But loaf cakes…they’re just the right size for us to each have a couple of slices while it’s still fresh.

This was going to be a simple key lime yogurt cake, but I just can’t leave well enough alone, and this thing was just crying out for graham cracker crumbs.  I had to listen.

So I added a graham cracker ‘swirl’, although it’s more like a layer, isn’t it?  This is what I ended up with after 4 batches of no swirl, not enough swirl, too much batter (cake bubbling over and setting of the smoke alarm), and finally, this: just enough swirl.  But the cake sank in the middle.   I just don’t care…do you care?  It tasted too good not to share with you!

So, yes.  Easy Key Lime Cake with Graham Crumb Swirl…super easy to throw together, and all those delicious key lime pie flavors!

Stay tuned for more episodes of Sweet Peas & Saffron.

 This cake is so fun...kind of like an inside-out key lime pie. A zesty key lime loaf cake has a seriously delicious graham cracker layer running right through it.
