Wondering if there are any recipes like this? Everything I'm seeing is with instant coffee or instant espresso. I have lots of real coffee, which is both good, cheap, and has a nice story behind it (so it's easy to sell), but would have to actually buy instant coffee just to do a recipe.
Is it possible to mix boiling water with the coffee grounds (instead of putting it through the machine) to get a higher concentration, filter it and use that?
Searching Google doesn't give great results because coffee and cake comes up with mostly non-coffee-flavored coffee cake.
