Brown Sugar, Garam Masala, and Pistachio Muffins

I'm pretty excited about these brown sugar, garam masala, and pistachio muffins. They had a warm, earthy, and deliciously complex flavor. Garam masala you ask? It's a blend of spices used in regional Indian cooking. I've read that the phrase in English means "warm spice." Epicurious describes it as the Indian equivalent to the French herbes de Provence, or the Chinese five spice blend.
