Preheat the oven to 350°F (180°C) and line the bottom of an 8-inch springform pan with parchment paper.
Peel the mandarin, remove the seeds, put them in the blender, and blend until smooth.
In a small bowl, sift flour, baking powder and salt, and set aside.
In another mixing bowl, whisk butter and sugar until light and fluffy.
Whisk in eggs, vanilla extract and yogurt until smooth and creamy.
Stir in the sifted flour mixture.
Stir in the Mandarin (keep 2 tablespoons to use for topping) until combined.
Pour the batter into the prepared springform and bake for 40-45 minutes.
Allow it to cool for about 10 minutes, then take it out of the springform pan and place it on a cooling rack.
Make The Glaze: Put the remaining mandarin orange juice in a small bowl, add the honey, and mix until combined. Brush the glaze over the cake while it’s still warm.
