As a mom I (sometimes) cringe when ever my girls are fully loaded with buttercream tinted with artificial coloring.

And as a baker?

Well, I don’t really care. I figure that if one consumes so much food coloring that it might hurt one’s health, then maybe one has more urgent things to worry about. AKA portion control (?!).

OK then. I reserve my right to worry about global warming, women’s equal pay and when Netflix will drop the next season of Stranger Things.

Now that I am care free and at ease, I can enjoy the ride and follow my golden rules:

  1. Nature Rocks!
  2. If it grows together, it goes together.
  3. When in doubt, Chocolate!

This recipe follows all three rules and the result is not only a moist, tender and fluffy explosion of flavors. It is also a tribute for Mother Nature.

I mean, just look at this beautiful color given by the Blackberries!

Not a fan of Blackberries? Go with Raspberries.

Don’t care for Rosemary? Skip it!

Now Lets Talk About This Rosemary Chocolate Cupcakes With Blackberries Buttercream Recipe:

Rosemary Chocolate Cupcakes:

  • Although require a standing mixer, you can just use a bowl and a hand mixer or whisker.
  • As alway, please make sure all the ingredients (excluding the milk and heavy cream) are at room temperature.
  • The milk and heavy cream should be warm when added to the mix. That is because the cocoa powder blooms in hot liquid. Please make sure the liquids are warm but not boiling, or else it will melt the chocolate chips.
  • The flavor of chopped fresh rosemary gets stronger during baking and over time. Feel free to to reduce the amount to 1 tsp or remove it completely.

BlackBerries Buttercream:

  • Below is a recipe for an Italian meringue buttercream. However, you can adopted this blackberry technique with any buttercream you may have in hand.
  • If using frozen blackberries, first make sure it’s defrosted completely. Second before mashing discard any liquid coming from the bag.
  • If you notice that the blackberry puree is too watery, place it in a small pan over the stove and reduce the liquid by 1/3-1/2. (about 10 minutes over low-medium heat)
  • When adding the puree to the buttercream, add 1 TBS at a time. Let the puree incorporate before adding more. This way you can control the color and texture of the buttercream.

    I have been wanting to try IBC but have a couple questions. First is stable is it in heat and does it need refrigeration once piped on a cupcake? Second, I like butter but think this is too much for my taste. I don’t like when frosting tastes like your eating a stick of pure butter. Can you add less or half high ratio shortening and would either compromise stability?

    1. Dikla

      Hi Caye!
      IBC is very stable and best to be eaten and store in room temperature. You can refrigerate it after piping and/or even freeze. Having said that I will add and say that it will melt if placed in a warm place.
      You can defiantly taste the butter in the BC but it is best not to change the ration in the recipe or you might end up with a sticky, pasty and unpleasant BC texture.
      You can add flavoring for taste or try different type of BC such as Old Fashion BC which is Milk base.

    Hello. The cupcakes look beautiful. What tip did you use to frost them? Can you tell me how you did it?

    1. Dikla

      Hi Carmen!

      Thank you so much! I use Wilton 1M TIP. I started the piping from the outside in and going up. Hope that helps.

  3. Dikla

    Thank you so much for your prompt response 🙂

    1. Dikla

      Any time! 😉

  4. Dikla

    It says a package of blackberries. What size package?

    1. Dikla

      Fresh from the produce department, usually it is 6 oz.

    Ok so I flubbed on the frosting! I for some reason did 1 cup water ? but it worked! And they are beautiful! Honestly wish I could share a photo! My youngest 18 months had me sidetracked ?….

    1. Dikla

      So glad it worked and that you liked it!!!
      Wish I could see it as well!

    2. Dikla

      hello! I was wondering if there is anything I could use to substitute the heavy cream

      1. Dikla

        You can either replace the milk and heavy cream with half and half or the heavy cream with milk.

    I was wondering if I could use the mix as a cake mix instead of cupcakes? If I can, how would that affect the bake time?

    1. Dikla

      Yes, you can bake the batter as cake, thou I am not sure for the time. I would set my timer for the amount of time the recipe calls for and check with a toothpick at the center of the cake. The cake is ready when the toothpick comes out clean.

  7. Dikla

    Hi please can you advise what type of sugar is used in the sponge as also the butter icing?

    1. Dikla

      Use regular white sugar

    Great recipe. Easy to follow. Yields beautiful cupcakes. I would’ve liked more of a blackberry flavor in the frosting, so in the future I would work on maybe concentrating the fruit flavor and then adding it to the cream to see if it would be fruitier.

    1. Dikla

      Thank you Esther, Next time you can concentrate the blackberry by reducing the liquids of the blackberry on the stove for about 15 minutes.

      1. Dikla

        Hello so I tried the recipe and for some reason the buttercream is very watery and clumpy but my butter was room temp and I followed everything to a t. I’m not sure what went wrong

        1. Dikla

          Hi Emma,
          So sorry to hear that, my guess is that either the meringue did not reach the high peak or that it needed more time in the mixer. Sometimes the emulsion breaks and we just need to beat it longer at high speed. I will do my best to post a tutorial about this.

    Overall, the flavors make for a really tasty and unique combination. If you don’t have a well equipped kitchen, these are a little too ambitious. I completely screwed up the fancy buttercream and had to start over with something that didn’t involve thermometers and homemade simple syrup!

    I loved the rosemary and chocolate combination, but did find the combination of that plus the icing overly sweet. Next time I will try leaving out the chocolate chips and switching to a cream cheese icing (with the berry flavor), but that said – I will definitely make these again. Thanks for the inspiring recipe!

    1. Dikla

      Thank you, Allie! Love your input, the one thing I lobe most about baking is that it inspires people to find their own voice and taste! thanks again!

    Is it normal for the icing to take FOREVER to cool down?

    1. Dikla

      Only if the meringue was not cool enough before adding the butter.

  11. Dikla

    No salt? I’m super excited to try these and am hoping salt wasn’t accidentally left out of instructions 😉

    1. Dikla

      The baking soda’s reaction will prodcue some salt so I did not add salt to the recipe. If you want, you can mix in 1/4 teaspoon of salt.

Leave me your lovely thoughts
