These are wonderful! Below is my recipe. I started with a recipe I found on line, but modified it significantly (like half as much walnuts and SIX times as much lavender!, and leaving out some other seasonings):
Ingredients:
2 C granulated sugar
1 TBSP dried lavender
8 oz good quality bittersweet chocolate, broken up
2 sticks unsalted butter
1/4 tsp salt
1 tsp vanilla
4 large eggs, beaten
1 C all-purpose flour
1 C chopped walnuts
Melt the butter and chocolate together on very low heat, stirring occasionally.
In food processor (or blender which is all I have) pulse the sugar and lavender together until well blended.
Beat the eggs lightly, then beat in the lavender sugar and vanilla.
When the egg mixture is smooth, sprinkle the flour on top and beat it in.
Once the mixture is smooth, slowly pour in the melted butter and chocolate, mixing as you pour.
Mix just until everything is blended. Stir in the chopped walnuts.
Pour into greased 9X9 pan and bake for half an hour or until toothpick comes out clean.
Allow to completely cool for at least an hour before slicing.
Sprinkle the tops lightly with a little extra lavender sugar.
Enjoy!
