Mix coffee granules and water together and put aside to cool
Preheat oven to 180 degrees fan forced, and place rack into middle of oven
Line base and sides of a round 20cm (base measurement) spring form tin with baking paper
Place sunflower seeds or almonds into TM bowl and mill 3 seconds / speed 7, put aside, do not clean bowl
Place sugar, olive oil and chocolate into TM bowl and heat 2 minutes / 50 / speed 2, then continue 1 minute / speed 2 without heat
Add eggs and vanilla and blend 10 seconds / speed 7
Add sunflower seeds, cocoa powder, bi carb soda and salt and blend 10 seconds / speed 4
Add coffee and water and blend 10 seconds / speed 4
Scrape around bowl and repeat 10 seconds / speed 4
Pour batter into cake tin and bake 35 minutes until the edges are firm and middle is just set (the edges will feel firm when lightly pressed with your finger, and the middle will feel quite soft - it will continue to firm up a little as it cools)
Remove from oven and allow tin to sit on a wire rack for 30 minutes
As the cake cools its dome will drop a little in the middle which is how it should be
Unclip sides of tin and remove, then slid the cake - with the baking paper still on its base - onto the cake rack to cool completely
Once cool upturn the cake (I used my left hand to hold it) and carefully remove the baking paper from the base (I used my right hand to do this) and place onto a serving tray
If desired just before serving sprinkle with icing sugar, or leave plain (which is what I like) and serve with coffee cream
