Make these fun little treats for parties or to give as edible gifts.
Making the sponge Preheat the oven to 180ºC. Grease a 20 cm round tin and line with parchment paper. Fit the K-Beater. Tip: Alternatively, use the Creaming Beater. Add butter, caster sugar, flour, baking powder, eggs and vanilla extract into the Appliance bowl. Mix for 2 minutes on speed 5 until combined. Tip: Start the machine on speed 1 and gradually increase speed. Transfer the batter into the tin. Bake for 25 minutes at 180ºC until a skewer inserted comes out clean. Remove from the oven and let cool in the tin for 5 minutes. Transfer to a wire rack and let cool completely. Once cooled, crumble the sponge cake into a large bowl. Tip: For a paler truffle filling, trim off the outer crust of the sponge before crumbling.
Making the truffles Line two baking trays with parchment paper. Clean the Appliance bowl and fit the Creaming Beater. Add butter, icing sugar and vanilla extract into the Appliance bowl, fit the Splashguard. Mix for 1 minute 30 seconds on speed 3 until combined and then scrape the bowl. Tip: Start the speed on 1 and gradually increase speed. Mix for 1 minute on speed 3 until combined. Then add sprinkles and the cake crumbs. Mix for 1 minute on speed 2 until combined. Roll the mixture into balls and place on the baking trays. Chill in the fridge for 30 minutes.
To finish Dip the truffles in the melted chocolate until coated and place back on the baking trays. Tip: Insert a cocktail stick or skewer into the truffle to help you dip them in the melted chocolate. Decorate with sprinkles. Allow to set.
