Buttermilk Butter Cake with Lavender Lemon Streusel

Here the last gasp cake of the summer. However, I doubt if this will be my last streusel cake of the season. I can't seem to stop creating new ones. These flavors scream "spring/summer," even though you can source these ingredients year round.

This lemon lavender cake was so delicious, I wanted to squeeze it in before the Fall flavor bombardment begins. 

I grow lavender in my garden every year. Every year, I have yet to take the time to figure out how to properly harvest and dry the buds. So, for this recipe, I used store bought dried lavender I had hanging out in my cabinet.

As with most streusel cakes, this one essentially has two steps, making the cake and making the streusel. There are two other steps to be aware of: 

1) Because the cake is yeasted, you will have to let the cake batter rise for 45 minutes.

2) Halfway through the baking, the cake is removed from the oven, more buttermilk is poured over the top, then the cake is returned for its final turn in the oven. 

This cake is perfect for afternoon tea/coffee breaks. The recipe serves 24. The lavender lemon special flavor makes it a perfect fit a brunch or daytime party any time of the year.
