For the dulce de leche topping; just use generous amounts of dulce de leche!
Instructions
Preheat your oven to 190 C (375 F) and grease your baking tin (20 cm) well and dust with flour.
Combine the eggs, and yogurt and dulce de leche in a bowl and mix well.
Combine the flour, cacao powder, baking powder, baking soda and salt in another bowl.
Combine the butter and the sugar together in your mixing bowl and cream with an electric mixer on medium speed until fluffy, which should take about 3 minutes, scrape down the sides of the bowl once or twice where necessary.
With the mixer turning on medium speed, pour your egg mixture into the bowl in a slow stream, again scraping down the sides where needed.
Turn the mixer on it's lowest speed and add your flour mixture, 1/2 cup at the time, scraping down the sides of the bowl after each addition or when needed.
Mix in your figs, your hazelnuts and the green tea until just combined, Do not overmix.
pour the batter into your prepared baking tin and smooth the surface with a rubber spatula. Bake the cake until it is firm and a wooden skewer comes out clean when put into the center. This took about 50 minutes in my oven.
Let cool for 5 minutes and then invert onto a wire rack to cool of completely.
Spread a layer of dulce de leche over the top of the cake once it is cooled and sprinkle the top with hazelnuts and dried figs.
