Step 1

FOR THE CAKE:

Step 2

Preheat the oven to 375 degrees.

Step 3

Sift the flour and ⅔ cup of sugar into a bowl and set aside.

Step 4

Add the egg whites, lemon juice, and salt to a large bowl. Beat with an electric mixer until foamy, soft peaks form. Slowly beat the remaining ⅔ cup of sugar in on medium speed. Up the speed to high and continue to beat until stiff peaks form (you'll know the whites are ready when you lift the beaters out of the bowl and flip them upside down - the egg whites on the beaters should stick straight up).

Step 5

Add the flour/sugar mixture, vanilla, and lavender oil( 1 drop for a lighter scent, 2 for a little stronger flavor) to the bowl and beat on low speed until only just barley mixed in.

Step 6

Place the blueberries on a paper towel and gently soak up any liquid - this will help the blueberries to not sink into the batter and to not streak it with purple color.

Step 7

Use a rubber spatula to fold the batter in 10-12 times, scraping the bowl as you go so that the flour and egg whites are gently mixed together.

Step 8

Pour the batter into an ungreased tube pan. Drop the pan on the counter once to remove air bubbles.

Step 9

Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and cracked.

Step 10

Remove from the oven and set upside down on the counter to cool.

Step 11

When the cake has cooled completely, run a knife along the sides of the cake and pull the base up from the sides. Run a knife along the bottom of the cake and invert onto a serving plate.

Step 12

TO TOP:

Step 13

Whisk the powdered sugar and cream together in a mixing bowl. Whisk in 1 tablespoon of blueberry juice at a time until desired consistency is reached - The icing should be thick, yet still run easily off the spoon.

Step 14

Drizzle the icing over the top of the cake, letting it run lightly down the sides. Place blossoms on top of the cake just before serving.

Step 15

Use a serrated knife to carefully cut slices. Cake can be refrigerated until it's ready to be served. Will keep in the fridge for several days.
