I'm a big fan of whole grain muffins, bran muffins, etc. I really ordered these for me thinking I'd have a regular breakfast that no one else would really touch. WRONG! My kids really like them - even though they're whole grain!
The blackberries give a nice tartness to the muffin, the crumb/streusel topping is lovely, and the quality of the whole grain gives kind of a creamy flavor rather than feeling like you're eating sawdust. They are a tad crumbly, but that's to be expected in a muffin.
Can't recommend these strongly enough.
