Hey, there!

Hope your weekend was great. It was the Kentucky Derby here in Louisville so we enjoyed watching that. We didn’t attend the Derby, but watched it on TV with our friends. It was a fun, but busy weekend.  Of course, like any weekend, I ate too much yummy food. 

It’s no secret that I love cupcakes and today I’ve got a fun new flavor to share. Blackberry Buttermilk Cupcakes!!! If you’ve noticed blackberries popping up more frequently in your store then buy some and make these cupcakes.

It’s very common to jump right into making a cobbler when we have fresh blackberries, but cupcakes are always great to make and I enjoy experimenting with unique flavors. Blackberry is not a typical flavor I would use to make cupcakes.

The cupcakes are made with buttermilk so they have a moist, yet, less cakey than normal texture about them. Very delicious and the blackberry buttercream is AAAAMAZING!!

To get all the blackberry flavor in these blackberry buttermilk cupcakes and the blackberry buttercream,you make a blackberry sauce. This sauce…well, just plan on keeping some in your refrigerator all summer long because it needs to be poured over ice cream every single night while binge watching shows on Netflix. 🙂
