Put white chocolate chips in a microwave bowl. Set the microwave at 50 percent and run for 30 seconds. Stir the chips and repeat, until all chips are melted. Mix in half of the Greek yogurt, stir to combine well, then proceed with the remaining yogurt. Stir until smooth, cover and chill in the fridge until set (you can do this a day ahead). Cut the strawberries in half lengthwise (quarter bigger ones). Combine in a bowl with sugar and black pepper and leave on the kitchen counter for about 30 minutes, or overnight.

Mix the cacao powder and sugar into the batter. To fry, proceed as in basic recipe.

To serve: Put a dollop of white chocolate yogurt mousse on each warm pancake and divide strawberries as needed. Drizzle just a little of the strawberry liquid left in the bowl overtop and serve immediately.
