Lavender Buttercream

Homemade Lavender Buttercream frosting for a layered cake.

Its not Spring without cake and Lavender Buttercream with fresh lavender.  Lightly floral flavored buttercream frosting using dried culinary lavender and fresh blueberry juice for natural coloring. Use for topping your cupcakes, layered cakes, or cookies for a tasty soft pinkish purple colored dessert.

Lavender is a strong herb that should be used sparingly to prevent overtaking a recipe. Its far more enjoyable as a background taste than eating an overly floral infused dessert.  This is why I only use a small amount mixed with vanilla extract. The flavor potency of lavender increases as it dries. Which means a recipe should use 1/3 dried flowers in comparison to fresh. In this recipe I have used 2 teaspoons of dried lavender for a large amount of buttercream to cover my cake. If I were to substitute with fresh lavender flowers I would use 6 teaspoons.

What is the difference between English and French Lavender?

English Lavender (L. Angustifolia) is the sweetest of all lavender species, and is most commonly used for baking. Some varieties even give off a hint of lemon.

French lavender has a scent of camphor and menthol, which is more medicinal flavor. It is also known to be toxic in very large quantities. So, its best to just enjoy the beautiful flowers as they bloom in your garden or use for decorations.

What is Culinary Lavender?

Culinary lavender is often known as dried flower petals/buds taken off a stem just after opening (stems as well). However, the flowers and leaves can also be used fresh. Lavandula Angustifolia is the  most common species of lavender for baking.

*If you’re new to experimenting with lavender start with just a teaspoon of the Organic Lavender and sugar mixture. Continue to add the rest into your frosting to see how your taste buds feel about floral enhancement.*

How to Make Lavender Buttercream Frosting:

  • Add 1/8 cup blueberries and 2 Tbsp water  into a small sauce pan. Heat on medium for 5-6 minutes, stirring and gently mashing the berries. Once the juices are pouring out into the saucepan remove from heat ands set aside.
  • Cool for 5 minutes.
  • Strain berries through a sieve into a small bowl. Discard berry solids.
  • Repeat with 1/8 cup blackberries using a clean saucepan and separate final bowl.
  • Add small amount of the blueish blueberry juice and the pinkish red blackberry juice to your finished buttercream.
  • Adding more blue will create a deeper purple. So, just play around until you find the shade you like!
  • You will have a blueberry lavender buttercream cake frosting that can also be used to fill macarons or cookie sandwiches!!
  • Another way to get a deeper purple Lavender Buttercream is to use juice from a purple potato! Slice and boil two purple potatoes, using the juice to dye the frosting.

    Hi, how much frosting would this make? Could I frost and fill a three layer 8 inch cake with one batch?

      This recipe makes enough for three 6 inch layers or two 8 inch layers. I would make a double batch for an 8 inch three layer, depending on how thick you like your frosting.

    Is this really supposed to have salt in it? There’s 1 tsp in the ingredients list but the instructions never say when/if to add it.

      Yes, you add salt in step 2. This helps balance the super sweetness from all the powdered sugar. If you prefer not to add it, that oj too 🙂
