Preheat the oven to 1800C. Grease and line a 18cm round cake tin.

In a medium bowl, mix together the ingredients in bag 1 with the dried apple pieces in bag 2. You may need to break the apple pieces apart after opening the bag.

Lightly beat 2 eggs and together with 150ml of water and add to the dry ingredients. Mix until fully combined and pour into the cake tin.

Place the tin in the oven for 25 minutes or until an inserted skewer comes out clean. Once cooked, allow to cool completely before applying frosting.

While the cake is cooling, empty out the ingredients in bag 3. Break it up using a fork and then mix 50ml of water to combine until smooth.

For a neater finish, flip the cake over and evenly spread the frosting over the cake. Top with a sprinkling of dried berries (in bag 4).

Give the cake to your dog and enjoy watching their face light up.
