Before we get to the recipe. This particular culinary sin is the child of the popular muffin (or cupcake, if you like...) and a Hungarian food that is called "dödölle" (Google Translator can read it for you). It is basically mashed potatoes with some fried onions and bacon made into a thick batter and baked.
Okay, enough lessons. Let's start.
Peel, wash and chop up the potatoes. Cook them in lightly salted water until they become soft.
While the potatoes are cooking, peel and chop up the onion.
Fry the bacon chops (no need to add any extra oil, they'll release enough fat to fry themselves).
When they're ready, use a spoon to remove the bacon chops from the hot fat (but leave the fat in the pan). Put the chopped onion in the bacon-juice and fry it.
If you want to use the bacon chops as decoration, you don't have to fry them completely. They'll be ready in the oven. You just need their fat for the onion. Although it is possible that this way you won't have enough fat, so you'll have to add some butter or oil too. But not too much.
When the potatoes are cooked, remove them from the water. Put them in a large bowl and mash them with a mixer. Stir in the fried onions.
So far we've made some mashed potatoes mixed with fried onions. You can add some milk and - as my grandmother used to - butter to the potatoes to soften it. I recommend you do that (especially if the potatoes are old, or not that good with quality).
Mix the potatoes with some flour and milk to get a muffin-like batter.
Cut the bacon slices in half. (You'll need 24 shorter slices for 12 pieces of cakes!) Prepare cupcake liners or molds (I have silicon molds and I don't like making muffins and cupcakes right in the liners because it is impossible to remove the paper when they're ready). Lay 2 slices of bacon across each other in each mold. Put some batter on top of the bacon with the help of a spoon. You can put the fried bacon on the top, or you can layer the batter and place the bacon chops between the layers (so they won't get burned in the oven).
I'll be honest with you, I have no idea how long it takes to bake these yummy cakes. They should be baked at 390 F (~200 C) for 20 minutes. But it's better if you check on them from time to time. They're ready when the potato-batter and bacon on the side looks well baked.
Attention! It is SUPERFILLING! :)
If you want to make cupcakes out of them, spread some sour cream on the top!
