Preheat your oven to 190C/ 170C Fan. Place 10 muffin cases into a cupcake tin.
In one bowl, Whisk together your oil, buttermilk, melted butter, vanilla and eggs.
In a separate bowl, Sieve both your sugars, cocoa, salt, flour, baking powder.
Once your dry ingredients are sieved add in your chopped up Toblerone and flaked almonds and mix.
Make a well in the centre of your dry ingredients then add in your bowl of wet ingredients.
Mix till just combined. This will take very little work. Do not over-mix. (Took me about 10 seconds)
Spoon into muffin cases evenly. Top with extra flaked almonds or Toblerone chunks if you wish.
Bake for 32-35 mins (Mine were perfect at 34mins)
Leave to cool completely.
Optional- Add a teaspoon of Nutella to the top of each muffin then place a piece of Toblerone on top.
