Hello Friends! Today I bring you a recipe for Lavender Cupcakes with Blackberry Frosting. These are amazingly light and delicious cupcakes that you are sure to enjoy.

I know I have been away for far too long. I have missed blogging so much, along with all of you. So much has happened since we last met. I hope you have all been well these past years and are ready to have some new culinary adventures with me. Thank you for visiting. For now, let me share this lavender cupcakes recipe with you. 

I thought I would start us off with a celebration recipe. These are the cupcakes I made this year for my darling lovie girl for her 13th Birthday. She decided on a Plant theme as she has a deep love for growing greenery. I chose to make Blackberry Lavender Cupcakes from the amazing Sally’s Baking Addiction site. I also ended up using the Blackberry Frosting from Natasha’s Kitchen as I wanted to use fresh blackberries in the recipe. Both of the recipes were fantastic and complimented one another fabulously.

Not surprisingly, the lavender cupcakes were a huge hit at the tiny gathering we did inside of an adorable local plant shop. My most surprising fan was my hubby, who is not a huge cupcake fan and certainly would never have picked these flavors on his own, as he is a classic chocolate guy normally. The lavender flavor is just the slightest lovely perfume of flavor in the cake and the blackberry frosting is heavenly.

 *Just a note to make sure to get culinary grade lavender for the recipe so it will be safe to eat. It is worth every step to make these cupcakes. Please don’t wait for an occasion, enjoy them today!

  • 1 stick unsalted butter, soft at room temp

  • 1/8 tsp fine sea salt

  • 8 oz 1 stick cream cheese, softened to room temp and cut into 8 pieces

  • 1/2 cup about 15 Blackberries to puree


  • Cupcakes
  • Make the lavender milk: In a small saucepan over low heat, bring the milk to a simmer. Remove from heat and immediately add the lavender. Set aside to steep for 20 minutes. Strain the milk through a fine-mesh sieve set over a bowl, then discard the lavender. Cool milk completely before using in cake batter. Can be made 1-2 days ahead and stored in the refrigerator. Bring to room temperature before using.
  • Make the lavender syrup: In a small saucepan over medium-high heat, bring the sugar and 1/2 cup water to a boil. Once boiling, reduce the heat to low and add the lavender. Simmer the syrup for 10 minutes. Remove from heat and steep until completely cool. Strain the syrup through a fine-mesh sieve set over a bowl, then discard the lavender. You will use this “soaking syrup” in step 8. Can be made 1-2 days ahead. Cover and keep at room temperature until ready to use.
  • Make the cake: Preheat the oven to 350°F (177°C). Grease three 8-inch cake pans, line with parchment paper, then grease the parchment paper. Parchment paper helps the cakes seamlessly release from the pans.
  • Stir the sour cream and cooled lavender milk together until combined. Set aside.
  • Sift the cake flour, sugar, baking powder, and salt in the bowl of a stand mixer. (Or if using a handheld mixer, any large mixing bowl.) With the paddle attachment, beat the ingredients together on low speed for a few seconds to gently combine. Add the butter, vanilla, and about 1/2 of the lavender milk/sour cream mixture. Mix on medium speed until the dry ingredients are moistened, about 1 minute. Stop the mixer and scrape down the sides and up the bottom of the bowl.
  • Whisk the eggs into the remaining lavender milk/sour cream mixture. With the mixer running on medium speed, add the egg mixture in 3 additions, mixing for about 15 seconds after each addition. Stop the mixer and scrape down the sides and up the bottom of the bowl, then mix for about 15 more seconds until batter is completely combined. Avoid over-mixing. Some small lumps are OK.
  • Pour batter evenly into cupcake pans (makes 24). Bake for around 18-20 minutes (rotate halfway) or until the cupcakes are baked through. To test for doneness, insert a toothpick into the center of the cake. If it comes out clean, it’s done. Allow cupcakes to cool completely in the pans set on a wire rack. The cakes must be completely cool before frosting.
  • Generously brush lavender syrup on the top of each cupcake. Then use your desired piping tip to frost all the cupcakes.
  • Blackberry Frosting Ingredients
  • Puree blackberries in a small food processor, or Immersion Hand Blender, then strain them through a fine mesh strainer, pushing them through with a spatula until all you have left in the strainer is seeds. Discard seeds and set the puree aside.
  • In the bowl of an electric stand mixer fitted with the whisk attachment, mix the 1 stick of softened butter with 1 1/2 cups powdered sugar and salt on low speed or until combined, scraping as necessary ~ 2 min. It may seem like it won’t come together at first, but it will. Give it a little time. Once the mixture is combined, increase speed to medium-high and beat until the cream is pale and fluffy (2-3 min).
  • Add cream cheese 1-piece at a time and mix until combined. Once all of the cream cheese is mixed in, continue to beat 2 more minutes until fluffy, scraping down the bowl as necessary. You need your frosting to be super smooth without any globs of cream cheese or they will get stuck in the piping star.
  • Pour blackberry puree over frosting and continue mixing until well incorporated. Refrigerate frosting 10 minutes before piping it onto the cupcakes. Once your cupcakes are cooled to room temp, you can decorate them.
