The No-Bake Crust
I start this lavender cake with a simple, no-bake graham cracker crust. If you have the time, you can also make my simple sponge cake base for the cake instead of using crackers. Try spreading more blackberry preserves over the graham crackers or cake for even more berry flavor!
The Lavender Mousse
The lavender mousse layer is my favorite part! It’s super fluffy and creamy! I make it with whipped cream, cream cheese, white chocolate, a touch of lavender extract and loads of blackberry preserves. To set the mousse, I use agar gelatin. This gelatin sets more firmly than regular gelatin and you need to use less of it. You can definitely use regular gelatin for this recipe, just double up the amounts.
The Jello Topping
And I know you guys will love the jello topping – it’s completely home-made, no packaged jello here! I also use agar gelatin for this layer and add sugar and lavender oil. I love how the blackberries look through the jello layer; so elegant and beautiful! Make sure to use food-grade lavender oil for this recipe; check the label before adding! I have my lavender oil and agar gelatin available in my Amazon shop; link here: https://tatyanaseverydayfood.com/shop/
Using a Cake Collar
For best results, use an acetate cake collar (affiliate link) for this blackberry cake. Line the pan with the acetate before assembling the cake. Once you have this lavender mousse cake assembled, let it set in the refrigerator for 4 hours, or leave it in overnight to set up more firmly. Remove the cake from the pan, peel away the acetate and then garnish with more blackberries, greens and roses!
