    Going for a more complex oatmeal stout, moderate thick body but not too heavy or sweet, would like to have character combo of chocolate, coffee, roast, mild caramel, mild toasted bread, mild nutty, mild stonefruit, mild floral/spicy hop.

    That's a pretty good amount of chocolate malt. I'd personally go for a little less. I like the toasted oats but it's flaked oats that will give you the mouthfeel normally associated with oatmeal stout. Looks pretty good overall. I'll assume you're going to cold brew the coffee, but what kind?

    Ok good deal, adjustments:

    2 lb flaked oat
    1.5 lb toasted flaked oat
    1.25 lb Chocolate malt

    Want to keep toasted flaked oat in because I’ve read it gives really nice oatmeal flavor, whereas non-toasted oat flakes are mostly body mouthfeel builder.

    Id also coarsely crush some good coffee bean and put it in the fermenter or secondary, for a more robust coffee flavor

    Yeah that’s how I add coffee. Usually 2-3 oz per 5 gallons, coarse crush with rolling pin, put in muslin bag or stainless steel infusion basket and steeped cold in the beer for 24-36 hrs.

    I usually add the beans after beer is carbed. Gas in through outpost at 1-2 psi while I open lid and add coffee then keep purging like this with lid on and vented for another few minutes. Same process when I remove coffee.

    For my tastes, less dark malt. I typically go with 1-1.5 lbs of the dark malts, typically a blend like you have, but less. I'm assuming your Carafa III is the dehusked type? If your preference is to go big with the dark malt, then it might suit you fine.

    Was great with exception to body. Actually came out a bit thin. IIRC the final gravity was 1.016 ish. Aroma and flavor were great though.
