Decadent chocolate cupcakes are topped with luscious blackberry buttercream. These cupcakes are beautiful and delicious!

If you like blackberries as much as I do, you’re going to love the fresh blackberry buttercream frosting on these cupcakes.

Blackberries are my favorite berries and when I was growing up, I picked many wild blackberries. Whether you buy blackberries from the store, grow your own, or pick them wild, you just can’t beat fresh blackberries.  

This blackberry cupcake recipe is perfect for a special occasion like a bridal shower or family gathering.

Tips For Making Blackberry Buttercream Frosting

This blackberry frosting is so good. You can cook the blackberries and strain them into a bowl the night before. Place in the refrigerator and chill until ready to use.

To strain, place a strainer over a bowl. Pour the blackberry mixture into the strainer. You can use a spatula to stir the fruit around in a circular motion to separate the blackberry puree from the seeds. Discard the seeds.

How do I store Chocolate Blackberry Cupcakes?

Cupcakes with buttercream frosting are best eaten the day you make them. They will keep at room temperature for up to two days. Make sure you store the cupcakes in an airtight container. These cupcakes will last 3-5 days when stored in the refrigerator. 

If I have leftover cupcakes, I always place them in the fridge, in an airtight container.
