This Lavender Cake is the cake of my dreams, and hopefully yours too! The cake portion is a moist yellow cake, and it's topped with blackberry-lavender whipped cream and mascarpone icing, making it ideal for any special occasion.
Whether it's for an upcoming birthday, anniversary or Mother's Day, this lavender cake is THE thing to make!
I'm absolutely obsessed with my vegan chocolate cake and my coconut flour cake -- both great options for those with dietary restrictions. But this lavender cake is my favorite classic cake recipe with a fun icing twist.
If you're a fan of lavender, you MUST try the icing, which is a combination of whipped cream and mascarpone that's infused with blackberry lavender syrup. ...yes you read that right!
Why you'll love this lavender cake
- It's a naked cake, so icing it is a breeze!
- The icing is SO GOOD -- the flavor and texture are insane
- The icing is naturally purple (i.e. NO food coloring) thanks to the blackberries
Flour: All purpose; feel free to substitute gluten free all purpose flour if you prefer.
Eggs: I haven't tested this recipe using flax eggs, though I imagine it would be fine.
Coconut oil: Coconut oil is my go-to oil for baking because it's a bit sweeter than other oils; after you melt it, make sure to wait until it's cooled to room temperature before incorporating it with the other wet ingredients or else it'll solidify.
Milk: Any kind! Almond milk and oat milk are my favorites.
Whipped cream: No substitution; the icing is essentially whipped cream, so you'll need to use heavy whipping cream.
Blackberries: Fresh or frozen.
Lavender: Culinary lavender is relatively easy to find these days -- you can find it in the bulk section at certain grocery stores, at your local tea/coffee shop or online.
Step 1: Get prepped. First, preheat the oven to 350° and line two 10" (or three 8") cake pans with parchment rounds. At this time, you should also melt the coconut oil.
Step 2: Mix dry ingredients. In a large bowl, stir the flour, baking powder and salt together and set aside.
Step 3: Whisk wet ingredients. In a separate bowl, cream the butter and sugar together for at least 1 minute. Then, add the eggs, oil, milk, water, and vanilla and stir to combine. Pour the dry ingredients into the wet and stir until batter is smooth.
Step 4: Bake. Distribute the batter evenly amongst the cake pans, then bake the cakes for 30 minutes, or until cake is slightly golden on the edges and a toothpick comes out clean. Leave the cake in the pan for 10 minutes, then carefully invert onto a cooling rack. Wait for the cakes to cool completely before icing them.
Step 5: Make the blackberry-lavender syrup. Add all of the syrup ingredients to a small saucepan, then bring the mixture to a boil. Reduce the heat to low and simmer for 10 minutes, using a wooden spoon to break down the blackberries. Remove from the heat and pour the syrup through a fine mesh strainer.
Step 6: Make the icing. Add the heavy cream to a large bowl or stand mixer and whisk for 4 minutes or until stiff peaks form. Add the sugar, mascarpone and blackberry syrup and whisk for 1-2 more minutes.
Step 7: Assemble the cake. Place one of the cakes on a flat surface, then add a large dollop of icing (approximately half of the icing) and use a rubber spatula or the back of a spoon to smooth it out. Repeat this process for the second cake. Slice and EAT UP!
Tips for making this lavender cake
-I used two 10" cake pans, but you could also use three 8" cake pans if that's easier.
-ALWAYS line your cake pans with parchment rounds so the cakes don't stick! You can buy rounds at most baking or craft stores (or online), or you can make your own by tracing parchment paper and cutting out a circle.
-Use fresh or frozen blackberries for the syrup -- whatever is easiest to find.
-My cake was done after 30 minutes, but I'd check yours at around 28 minutes since every oven is different. It may also take closer to 35 minutes, so just keep your eyes on the cake.
Where can I buy culinary lavender?
I know some grocery stores sell it (like Fresh Thyme and I believe Giant Eagle), at a local tea shop or you can purchase some online.
Can the icing be made ahead of time?
Yes and no. You can certainly make the blackberry lavender simple syrup ahead of time, and refrigerate until you're ready to use it, but I'd wait to make the whipped cream. You want the lavender flavor to be FRESH, so I wouldn't prep it too far in advance.

- 6 oz. blackberries fresh or frozen
- 2 tablespoon culinary lavender
- 1 cup sugar
- 1 cup water
for the icing:
- ½ cup heavy whipping cream
- ¼ cup sugar
- 8 oz. mascarpone room temperature
- ½ cup blackberry lavender syrup
- Preheat oven to 350°. Line two 10" round cake pans with parchment rounds (or grease with coconut oil). Melt the coconut oil then set it aside; wait for the oil to cool to room temperature before using it.
- Combine flour, baking powder and salt together in a large bowl and set aside.
- In a separate bowl, cream butter and sugar together; then, add eggs, coconut oil, milk, water, and vanilla extract and whisk to combine.
- Last, combine wet and dry ingredients with an electric mixer, then the pour batter evenly into cake pans.
- Bake cakes for 30-35 minutes or until a toothpick comes out clean. Wait 10 minutes or so, then carefully invert cakes onto a cooling rack and wait for them to cool completely before icing.
for the simple syrup:
- While cakes are cooling, make the syrup. Add all ingredients to a saucepan and bring mixture to a boil, then reduce to a simmer and simmer for 10 minutes, using a wooden spoon to break down the blackberries. After 10 minutes, pour mixture through a fine mesh strainer, saving the syrup and discarding the blackberries and lavender. Set syrup aside.
for the icing:
- Whisk whipping cream for approximately 4 minutes or until stiff peaks form. Then, add the sugar and mascarpone and whisk again for another minute before adding in the blackberry lavender syrup. The icing should be soft and fluffy like whipped cream.
- Set one of the cakes on your cake stand, then place a dollop of icing on top and use a rubber spatula to smooth icing out, then place a second cake on top and repeat this process. Feel free to add toasted almonds and/or blackberries on top of the top cake for added flavor and texture. Slice and enjoy!

I made this and it was pretty good! The only thing was that after following the instructions for the icing, it became a bit bumpy and started leaking. What would be your suggestion to ensure it has the consistency of whipped cream? Thanks!
Hi! I'm glad you liked the cake. When you say the icing was bumpy, do you mean there were lumps in it? The only thing I can think of is that perhaps the mascarpone was too cold... I'll adjust the instructions to note that it should be at room temperature before incorporating it in with the whipped cream.
Hi Erin -yes:)! Thanks so much...aha! that is why..makes sense now. Will make sure as I was practicing for my b-day cake.
I love being able to share my favorite vegan tip for anything with eggs! Aquafaba (bean water) is the liquid leftover from beans (i like to just use canned, its more concentrated). Garbanzo/chickpeas are the most common used because theres no color and zero bean taste. AND! You can use it in meringues, it whips up the same. Which means you can make a shortening based buttercream and still whip it like egg whites. Im not exact on the measurments but you can look it up and youll find out all about it. 😊
Love this trick -- thanks for sharing!
can you recommend a gluten free option for this cake? It looks delicious!
I haven't tested a GF version, but I'm guessing gluten free all purpose 1:1 baking flour would work!

Aaaah! I made this last night. When I went to pull it out of the fridge to let it thaw, I took a peek and I have GREEN spots on my lavender frosting! It looks like bread mold! Is that normal????
Oh no!! So I don't think it's normal necessarily and it hasn't happened to me, but I did some Googling and found this article which might be helpful: https://www.cakecentral.com/forum/t/2392/icing-discoloration -- I'm sorry this happened!
Great recipe! Are you using fresh or dried lavender?
Your cake is beautiful! Happy Birthday!!!
