Back in 2018, I hadn't started this blog yet. I just watched a lot of cooking shows and looked for any opportunity to bake and try all these things I was learning. One night, for a dissertation workshop, I decided to make a spice cake with apple filling and caramel frosting. I found the photo on my Instagram recently, and I decided to remake it with a few little twists. Now, it's a dulce de leche spice cake, and it's so much better than the past version.
This spice cake is soft and full of all your favorite fall flavors. Topped with a creamy dulce de leche frosting and a hidden layer of apple butter, and it's one of my favorite fall desserts. While fall is slowly coming to an end as winter is approaching, I will definitely be making this cake long past the end of November. It's too good to leave behind!
What kind of Dulce de Leche should I use?
You can buy any kind of store bought brand, but I make my own. It's super simple, and requires very little work.
Take 2 cans of sweetened condense milk, place in a crock pot and cover with water.
Turn it on high for 5 hours, let cool, and you're good to go!
Now, you have homemade dulce de leche, which is way better than store bought.

Why apple butter?
Look, you don't have to put the apple butter in there, but you'd be seriously missing out if you don't. I make my own apple butter (again, in a crock pot), but that takes all day. Just buy store bought, you really can't go wrong. There's so many great brands out there, any of them will be fine.
You can also peel and chop some apples and sauté them in a pan with butter, brown sugar, and some cinnamon until the apples are tender. Just watch the "juice." You don't want to add too much liquid to the center, so it might be best to drain the mixture before adding to the center of the cake. Doing this option allows some fun textual contrast to the cake.
It's a win-win whichever one you choose.
How do I store this cake?
In the fridge!
Seriously, dulce de leche is a lot looser than caramel. If you don't put this in the fridge, you will have a mess on your hands, especially after your pour it on top of the cake. Save yourself the headache of cleaning up a sticky, sugary mess and just store yourdulce de leche spice cake in your fridge. I'm begging you.
