Cinnamon toast is perfect with a cup of tea! I’ve loved it since childhood. Sometimes I will butter a tortilla, sprinkle it with cinnamon and sugar, and bake it until it is crispy for a sort-of sopapilla treat.
When my mother would bake scratch biscuits, we would take the excess dough, roll it out, then butter/sugar/cinnamon the heck out of it to make ersatz snickerdoodles.
I like your tortilla/sopapilla hybrid idea; sounds tasty.
When my younger sister eats peanut butter toast, she always generously butters the toast before spreading the peanut butter. Yeah, it probably tastes good, but it kinda squicks me out.
Of course, I’ll eat Wheat Thin “sandwiches” with a pat of butter as the filling. Gross! But tasty.
There’s a spaghetti-and-wieners dish that my siblings and I have eaten since early childhood. My mom got the recipe from the newspaper, IIRC. We still eat it. My brother is visiting from Costa Rica in a few weeks, and it’s one of the food items he has to have.
It’s really simple, but really tasty. Slice the wieners about a quarter inch thick, sautee with onions until both are brown. Add allspice and cloves and salt and continue to sautee to cook the spices. Add a large can of tomato juice and continue to cook. Stir in cooked spaghetti and serve.
The original recipe was a bit light on the spice compared to how we like it, so my sister (younger, who’s usually the one to make it) just keeps adding spices until the sauce is the right brownish color.
My older sister tried making it for her family, but no one likes it. She’ll sometimes make a pot just for herself and take days to finish it.
Yeah, we ate it when we were kids – always on toast, not bread. And I read about Nancy and Bess and George eating it in an old 1930s era Nancy Drew book. Nancy Drew was not white trash. She was the daughter of Carson Drew, noted attorney!
That’s what my mom did with scraps of pie dough. She’d roll the dough flat, then butter it, generously sprinkle with cinnamon and sugar, roll it up like a snake and bake it. Then, slice it when cool. I’ve still never tasted a better cinnamon roll.
Related: when i make pie, i make the crust bigger than strictly needed, and cut off the excess. Then i cut the scraps into cookie-sized pieces (or smaller), and sprinkle with cinnamon. I put them in the oven after i turn down the temp (my pies start at 450F and then i reduce the temp after ~20 minutes) and cook until light brown and crispy. They are delicious.
The pie crust isn’t sweet, but it’s very buttery, and i don’t miss the sugar in these “scrap cookies”.
I don’t know how she did it, but my mother’s pie crust was so thin, it only had one side! 
Seriously, you could see through it – she used one of those sheet-of-plastic gauge dealies that let you know how wide to roll the dough and you could see the dimensions on the face through the dough. (I’ll research what those sheet dealies are called and get back to you.)
Found it: Silicone Pastry Mat.
Pastry mats. Pastry rolling mats if you want to get fancy. Tupperware made one of the first ones several decades ago.
I love my silicon pastry rolling mat.
When they cool down a little I’ll slather on top anything sweet I can find and call it a tart. There’s always some kind of jelly, jam, or marmalade type of stuff around, or chocolate, or left over frosting in a can, or who something I can use.
In the biscuit family - some people cut canned biscuits into quarters, fry them, then toss with sugar or cinnamon sugar. The little doughnuts are like Chinese buffet doughnuts.
They’re o.k. in a pinch, but canned biscuits always have a slightly off taste for me.
lol, I still eat like im 15 so … tho if you have a brand that’s been around forever and all of a sudden it gets crappy blame ConAgra …their business strategy in recent years is to buy halfway decent brands and then cheap out the ingredients to the point the store brands are better … like chef Boyardee…
As a child, we loved buttered bread, sprinkled with cinnamon and sugar. We even had a shaker just for that combo, and you can actually buy the mix in the spice department.
Cinnamon toast. We bought the sugar & cinnamon mix in a shaker bottle.
Spread softened margarine on bread. Need a thick layer. Sprinkle Cinnamon mix over bread.
Toast on a baking sheet for a few minutes.
It was my favorite childhood snack.
I still occasionally make it.
$3.10 a bottle. It’ll last for several years in the cabinet.

My mom (and me) slice before baking. One of the best things about making my own pie pastry.
Interestingly enough, my mom and her cousins make pie crust a lot thinner than other people. Everyone raves about their pies.
I’ve done this, but without the baking. I’ll have to try that next time. Heck, I’ve got tortillas that are getting close to the best buy date - might be a good use. 
My husband does this. I decided to make him REAL cinnamon toast!
Place one slice white bread on cookie sheet. Take one pat of butter, quarter it and put it one four quadrants of the bread. Sprinkle extremely generously with sugar. Top with lots of cinnamon. Broil about two minutes until sugar caramelizes. Take a bite and burn your mouth on the HOT sugar.
I also like what I call “toasted cheese.” One slice white bread topped with one slice Kraft American cheese*. Broil about two or three minutes until cheese puffs up and starts to speckle brown.
*Other cheeses don’t puff!
My mom made this with white bread and Velveeta cheese.
Velvetta makes wonderful toasted cheese.
I like it on ham & cheese sandwiches .
I don’t consider a lot of these replies “kids’ foods” but I’ll go along with it. Here are my child-like foods:
PB&J - white bread
Grilled cheese - white bread and Velveeta
Mac n cheese - either box with powder or box with sauce
Chicken strips and nuggets
Cookies (really? doesn’t everyone eat cookies?)
Popcorn with lots of butter and salt
Chips
Hot dogs - plain
Corn dogs
Various candy bars
Chocolate malts
Ice cream treats - sandwiches, fudge bars, creamsicles, drumsticks, etc.
Lucky Charms
The most kiddish thing I still eat is something my mom would make us for breakfast on occasion -
Chocolate Malt-O-Meal made according to the box directions with a splash of milk and a handful of mini marshmallows stirred in to get melty. It was probably the only way she could get us to eat hot cereal!
Another is something my grandma would always give me. A mug of half coffee, half milk and 3 spoons of sugar. In this, dunk hard cinnamon/sugar toast slathered with peanut butter. MMM MMM MMM
This is what I grew up with as “grilled cheese.” I didn’t have a real grilled cheese until I was maybe 12 or 13 years old. Sometimes my mom would add some sliced onion or tomato before baking it. The onion was so good.
