Break 1 packet of bourbon biscuits into smaller pieces and grind them into a fine crumb.

Transfer the biscuit crumbs to a mixing bowl and add about half of the milk.

Mix the batter and gradually add the remaining milk until it is smooth and thick but pourable.

Add 1 tsp baking soda and gently mix just until it is evenly incorporated.

Cut the milk chocolate into 6 small pieces and set them aside for the centres.

Brush the ape mould cavities with 1 tsp ghee and preheat the mould over low heat.

Fill each mould cavity about halfway with the biscuit batter and place 1 piece of milk chocolate in each cavity.

Cover the chocolate with the remaining batter, filling each cavity about three-quarters full.

Cover the mould and cook the cake bites on low heat for 3 minutes.

Turn the cake bites over and cook for about 2 more minutes, until set and cooked through.

Remove the warm chocolate-filled cake bites from the mould and serve immediately.
