In a medium saucepan add yogurt, half and half, butter, maple syrup and sea salt and bring to a boil while stirring. Remove from heat and let sit 3-4 minutes.
Blend together almond flour, eggs, vanilla powder, baking powder, orange rind and yogurt mixture until smooth.
Butter the bottom of an 8 inch circular tin. Transfer the batter to the pan and spread into an even layer. Bake at 350°F for approximately 30-35 minutes or until toothpick comes out clean in the middle.
Cut into thin triangles and enjoy! You can also lightly dust with confectionary sugar or top with a dollop of real whipped cream if desired.
Can adjust orange rind up or down depending on tastes. If you want a chocolate/orange cake melt 2-3 ounces of dark chocolate (over 85%) and drizzle into batter before baking.Can use vanilla extract instead of vanilla powder (substitute 1:1).
