I think you have to be pretty ballsy to call something the best, but ballsy is how I feel about this coffee cake. So I’m confident about labeling it as the best I’ve ever tasted!
I’m a huge fan of coffee cake and some might say a purist. I actually will only eat it with a cup of coffee and for me it has to have cinnamon in it. So why do I love this coffee cake more than (almost) anything else in the whole wide world? It tastes of pure butter…and there’s not many people who don’t like butter. The original recipe which you can find here has a great story to it, so you should check that out even if you hate coffee cake. For this version I just added blackberries and lots of fresh rosemary, which works great in sweet recipes. It’s totally not just for chicken and lamb!
Let’s not forget that it has a good amount of sour cream in it too. Between that and the one and a half sticks of butter it’s really, really moist. Have I sold this coffee cake to you yet? Whether you prefer the more traditional coffee cake or you feel like being the awesome person at your next brunch pot luck with this blackberry version, either one of these will make you ditch store bought cake forever!
