Step 1

Heat oven & prep pan: Preheat the oven to 180°C (350°F) Grease with butter a 2 lb loaf pan 23 x 14cm (9 x 5.5-inch) and line the base and sides with parchment paper.

Step 2

Whisk eggs & sugar: In a large bowl, add the eggs, sugar, and vanilla extract and whisk until pale and light - this takes approximately one minute.

Step 3

Mix in yogurt & oil: Add the Greek yogurt and oil and whisk until fully combined.

Step 4

Sift in dry ingredients: Sift into the bowl the flour, baking powder, and salt. Then add the ground Earl Grey tea leaves. (See note)Fold together gently: Using a spatula, fold gently until a few streaks of flour remain.

Step 5

Bake: Pour batter into the prepared pan and bake on the centre shelf for 50-55 minutes until golden brown and the sponge springs back or a toothpick inserted into the centre comes out clean. If the cake is browning too quickly then cover it in aluminium foil and continue to bake. Cool on a wire rack for ten minutes, then remove from the pan to cool completely.

Step 6

Whisk: Add powdered icing sugar and orange juice into a small bowl and whisk together. Add Greek yogurt and whisk until combined. If the glaze is too runny, then add more powdered sugar 30g (¼ cup) at a time, and mix until desired consistency is reached.

Step 7

Pour: Pour glaze over the cooled cake and set aside for ten minutes for the glaze to harden. Slice and serve.
