A frosted donut topped with crunchy fruity cereal. Equal amounts of two different cereal flavors are used, hence the name "Parallel serial". I chose FW Fruity Flakes and TPA Silly Rabbit, as the Silly Rabbit helps smooth out and tone down the brashness of the Fruity Flakes. These can be substituted for your own two favorite cereal flavors – I've tried a few different combinations and each worked fine due to the low concentrations used (not enough to bring out any of the "off" notes as can happen when using most cereal flavors in higher amounts). The combination of FW Fruity Flakes and TPA Silly Rabbit was my personal favorite.

If you get the "Play-doh" flavor from CAP Glazed Doughnut, you might want to consider switching the concentrations for it and CAP Sugar Cookie, using 2% CAP Glazed Doughnut and 3.5% CAP Sugar Cookie. But it's only used at 3.5% here, and the cereal flavors help push that particular note deep in the background, so I would advise trying it as it is first, then adjust from there.

FW Cake (Yellow) can be swapped out for CAP Yellow Cake without much of a change if you have qualms about the fructose. But the FW version is definitely better here.

The acetyl pyrazine is optional, but it does help add a bit of crunchiness to the cereal on top.

This is surprisingly good as a shake and vape, but does improve a bit after a few days of steeping.

I tried Wafflepriest1's A.J.S.M. (Apple Jacks in Strawberry Milk) recipe and found it great, but it didn't quite match the title. While this was explained in the description – it's more of a mixture of Cinnamon Toast Crunch and Apple Jacks – I decided to try and make it closer to just Apple Jacks cereal.

Apple Jacks does of course have cinnamon flavor, just not as much as in the original recipe, so CAP Cinnamon Danish Swirl is reduced significantly. FW makes an Apple Jacks flavor, but unfortunately all I get from it is a spiced apple cider, with no cereal or bakery notes of any kind. But I've found it to work well in relatively small amounts as part of an Apple Jacks recipe. So it is added in at 2%, and FA Fuji is cut in half to 1.5% to compensate for the extra apple flavor.

I also increased FA Meringue to 1.75%. I use it at 1.5–2% in pretty much any cereal recipe I make, since it mimics the sugary coating of "kids cereals" so damn perfectly. It also helps tie the cereal and milk flavors together.

And since the milk in the original recipe was too low for my taste, I added 1% of FW Hazelnut to thicken it up. This is another flavor that winds up in almost all of my cereal recipes since it works so well in the milk.

This is quite vapeable as a shake and vape, but definitely improves after a few days.

I still think it needs more milk, so that is something I will work on. Perhaps a bit of TFA Bavarian Cream and/or a touch of FA Vienna Cream, but I haven't tested anything yet.

A rich cinnamon roll drizzled with cream cheese icing, using common flavors that you probably already have all (or at least most) of. FW Cake (Yellow) can be substituted for CAP Yellow Cake or CAP Vanilla Cupcake without a huge effect on the recipe if you have concerns about using this flavor.
