Heat heavy cream in a small saucepan until just simmering. Place white chocolate and raspberries in a heatproof bowl, then pour the hot cream over them. Let sit for 2 minutes, stir until smooth and fully melted. Mash raspberries thoroughly and, if desired, strain through a fine sieve to remove seeds. Chill ganache in the refrigerator until thickened but still pipeable, about 30 to 40 minutes.

In a large bowl, whisk together flour, granulated sugar, baking powder, baking soda, and salt. In a separate bowl, whisk eggs, buttermilk, whole milk, melted butter, and vanilla extract. Pour wet ingredients into the dry mixture and stir until just combined, taking care not to overmix.

Line a baking sheet with parchment paper. Transfer chilled ganache to a piping bag. For each doncake, scoop two heaping tablespoons of batter onto the baking sheet and flatten into a disk approximately 8 cm in diameter. Pipe a generous teaspoon of ganache into the center. Cover with an additional tablespoon of batter, then gently seal the edges and shape into a thick donut ring. Use a small round cutter to form a hole in the centre if preferred. Repeat until all batter and ganache are used.

Heat oil in a deep fryer or heavy pot to 175°C. Fry doncakes in batches for 2 to 3 minutes per side, or until golden brown and crisp. Remove with a slotted spoon and drain on paper towels. Allow to cool slightly before glazing.

For the glaze, combine milk chocolate, heavy cream, and butter in a heatproof bowl. Melt gently over simmering water, stirring until glossy and smooth. Dip each doncake halfway into the glaze and set on a wire rack to allow excess to drip off and glaze to set. Garnish with freeze-dried raspberries or white chocolate shavings as desired.
