I found several recipes online for Lavender Cupcakes and kind of combined and tweaked them to fit my purposes. Be sure to get food grade lavender flowers. I got mine at a health food store in the bulk food section. Mix about 1/3 c. of lavender with 2 c. sugar and let sit for about 2 weeks to make lavender sugar.
I tried this recipe and it was VERY good! I made one change, however, and used a lavender cream filling. Really pumped up the flavor.
