1sachetPaneangeli baking mix with vanillaor replace it with 2 teaspoons baking powder + 1/2 teaspoon baking soda + vanilla (how much depends on the type you use)
150grGreek yogurt
1barsemi-dark chocolatemilk chocolate is also fine
powder sugar for dusting
Instructions
Add the flour, potato starch, and baking powder mix to your medium sized bowl. Mix well to incorporate everything together; set aside.
Crack all your eggs in your largest bowl.
Grate the skin of your washed and dried orange.
Beat with your electric mixer.
Then measure the oil and add that too. You can beat again.
Add the yogurt and beat some more.
Finally, add the sugar and beat again.
It's time to add the dry ingredients, that is the flours you previously prepared in your other bowl. Add 1/3 of that mixture to the wet mixture, and beat.
Repeat with the second and third part of the flour mixture. PS: I have this habit of covering the batter while I mix it, so that it doesn't splash. I simply use a clean cloth that's large enough to cover the entire bowl and all the sides plus it's easy to wash.
Once you have added all the flour, your cake batter is ready.
Add some oil to your baking dish and grease it using a napkin or your clean hands. Don't leave too much oil though.
Pre-heat your oven at 160 degrees Celsius.
Pour the batter into your oiled baking dish.
Take your chocolate bar and break it into two halves. Add one half to the centre of your cake, and then stack the other half on top. Make sure your cake batter covers the chocolate.This will create a melted chocolate heart in the centre, but only when the cake is warm. I always warm up my slice in the microwave, anyway.Otherwise, you can cut the chocolate into squares and spread them evenly across the batter.
Bake in the oven for 30 minutes, or until your toothpick comes out clean. I suggest checking it after 25 minutes.
Once your tootpick comes out clean, take it out of the oven, sprinkle it with icing sugar and leave it to cool for 10 minutes.
Then transfer to a serving plate or a cake stand, and serve. Enjoy a slice hot so you can get some melted chocolate goodness.
Notes
If you choose to cut the cake into 10 slices, the calories will be 300 per slice.
