Crumb Instructions: Mix all ingredients in a small bowl until large crumbs form.
Cake Instructions: Preheat oven to 350 F. Beat butter, brown sugar, and white sugar in a medium-sized mixing bowl until light and fluffy. Beat in egg. Beat in sour cream. In a separate medium-sized mixing bowl, whisk together flour, baking powder, salt, and turmeric chai powder. Add flour mixture to wet ingredients a little bit at a time until just combined. Mix in milk. Place the batter into a greased 4" round cake pan or two small greased vessels such as the Revol porcelain described in this post. Top with the crumbs. Bake for 40 minutes or until a toothpick inserted into the center of the cake comes out clean.
Glaze Instructions: Mix glaze ingredients together and drizzle over cooled cakes. Add more powdered sugar as needed to make the glaze a good consistency to drizzle.
