I just got some Cinnamon Coffee Cake by Capella as well and I'm also fighting that Schnapps/Red Hot spice. @15% it smells promising after a few days' steep (complex sweet notes, slightly mellowing cinnamon, hint of bakery exhale), but the taste is ambiguously sweett while the bite remains. I've had plain Cinnamon and couldn't get it to play nice with anything (gave up years ago on trying to mixing with that), and the CCC reminds me of it a lot. If I have to drop the % so low to get rid of the bite that it can't work as a standalone, I'll try some cake batter or vanilla cupcake and/or maybe some brown sugar flavor. One thing I haven't tried is clobbering it with sucralose (>2%). Maybe I can use it to spike pastry recipes in the ballpark of 2%. I wonder how it behaves with creams and custards in this additive range.
That artificial cinnamon kick yields mixed reviews. As such it stays unpopular and no one's really figured it out yet it that I've read. Most reviews love it or hate it - I think fans accept the bite rather than try to blend it out, IDK.
Green Apple and Cinnamon anything is going to be a very very tough mix. I tried 3 or 4 different ratios of Granny Smith and Cinnamon and then I never wanted to taste them together again lol. Both have a bite that conflicts horribly - maybe try a red or fuji apple, something less tart and acidic tasting. IMO get some caramel or dulce de leche, it's delicious at almost any ratio with apple. Caramel Apple (7% and 7% will get you close) was one of my EDV for my first year of vaping DIY liquids. The dark body of caramel and the bite of green apple mix well enough to shake and vape decent even. Never tried caramel with anything cinnamon but the odds are in your favor I think.
