[Request] Help me save butter and flour I mistakenly mixed together (maybe involving blueberries?)

I started baking a cake before having my morning coffee and creamed together my butter and my flour. Yep. I started over for that recipe, but now I have 3 cups flour mixed with 1.5 cups butter. What can I make with this mistake mix? I also have a bunch of blueberries so I was thinking a muffin or quickbread maybe? Obviously the recipe can't involve creaming the butter with sugar. -_-

Thanks!
