Ingredients :

• Self-raising flour — Flour that already contains baking powder in the right proportions. If you don’t have any, mix 3 cups of regular flour with 4 teaspoons of baking powder and a pinch of salt.
• Buttermilk — Found in the dairy aisle. It makes the dough more supple and slightly tangy, which balances the sweetness of the glaze. Can’t find it? A tablespoon of white vinegar in whole milk, wait 5 minutes — it does exactly the same thing.
• Brown sugar — Cassonade or dark brown sugar, not the light tan sugar used for coffee. This is what gives the filling that slightly caramelized and deep flavor.
• Ground cinnamon — Don’t hold back. Standard supermarket cinnamon works great. If you want a more complex note, add a small pinch of ground cardamom — the two pair perfectly.
