I made muffins that called for 1 cup oats and 1.5 cups almond flour. What is the correct Brocha?
The brocha is mezonos. The rule is that whenever one of the five grains is added to a mixture the bracha will be mezonos, unless it is only there as a binder etc. in this recipe it seems to be an integral part of the recipe and not just there to give the muffin some body.
