Thank you to #goaheadmakemylunch for the recipe. I have modified it slightly (reduced the sugar and increased the sweet potato)

Ingredients:

300g sweet potato

200g white chocolate

150g Butter

30g water

200g Dark Brown Sugar

250g Self Raising Flour

2 eggs

1 tablespoon caramel syrup

1/2 teaspoon Baking Powder

Method:

1. Chop sweet potato 5 seconds/speed 7. Scrape down sides and add water.

2. Cook 3 minutes/Varoma/speed 1.

3. Blend 10 seconds/speed 7, scrape sides, blend again 10 seconds/speed 7.

4. Add chocolate, butter and sugar and cook 6 minutes/90 deg/speed 1.

5. Add flour, eggs, caramel syrup and Baking Powder then mix 10 seconds/speed 4.

6. Pour into prepared cake tin and cook 45 minutes at 160 degrees  until skewer comes out clean. Tip: I used a Bundt tin to prevent the cake sinking.

7. Serve drizzled with more caramel sauce and white chocolate ganache if desired.
