Dark grain bread: I saved some of the grains (maris otter, chocolate malt, and caramunich) from this batch and used them in a bread recipe. It's a simple french bread recipe, but with the added grains. The milled grains were taken for a spin in a food processor before adding them to the bread. IMO, this step is a requirement for spent grain bread. Otherwise, the grains get stuck in your teeth. I replace water in the bread recipe with the "failed" stout.
Stout brownies: Based on this recipe, these brownies are rich and moist. Note that the eggs are replaced with applesauce (2 tbsp per egg) and the white chocolate chips with walnuts.
I spread some fruit jam on the bread and paired it with a Belgian dark strong ale. Fantastic!
