More detailed directions (with pictures)
Start out with collecting our ingredients together for this scrumptious cake.
Separate the egg whites from the yolk. Mix the dry ingredients (flour and baking powder) by passing them through a sieve couple of times.
Grate the Orange zest from the orange.
Squeeze the oranges using a hand juicer (or any other method you have at your disposal) and pass it through a sieve.
Mix the orange juice, zest and coconut sugar in a bowl
Add stevia and mix all these ingredients using a whisk
Add the egg yolks to the mix
Mix all ingredients, until the coconut sugar is dissolved
Add the natural orange color (optional)
Add the dry ingredients (flour and baking powder) with milk and mix well with a whisk or with a mixer on medium speed for 2 minutes
Add butter to the mix, the butter should be at room temperature and soft, if not melt it in a microwave
Take the egg whites in the bowl and use a whisk to get stiff peaks. You may use a hand mixer to beat the eggs.
This process will take 2-3 minutes when using a whisk.
Add the egg whites to the mix.
Mix the ingredients well; do not beat much, just enough to mix the egg whites with the cake mix.
Pour the mix in a well-greased baking tin
Place in the pre-heated oven with a water bath and bake for 50 to 55 minutes or until the toothpick comes out clean. The water bath adds moisture to the oven and provides a more even, slower heat source than the direct heat of an oven
Allow the cake to cool in the baking tin, garnish with the leftover orange zest. Serve warm
