Ingredients
Method
- Heat oven to 350°F (175°C). Grease a 4 inch pan, line the base, and dust with sugar if desired.
- Whisk flour, sugar, baking powder, and salt. Rub orange zest into the sugar until fragrant.
- In a separate bowl, whisk egg, oil, orange juice, and yogurt until smooth.
- Fold wet mixture into dry, pour into the pan, and smooth the top.
- Bake 18 to 22 minutes until springy and a toothpick comes out with moist crumbs.
- Cool 10 minutes in the pan, remove, cool completely, dust with powdered sugar, and slice.
Notes
If the middle domes too quickly, gently press it down with a flat spatula right after it comes out of the oven. This keeps the top level for stacking or decorating later. For a deeper orange colour, add a tiny drop of natural orange food colouring to the wet mixture.
