First, prepare your "dirt." Place the chocolate sandwich biscuits (filling and all) into a food processor and pulse until you have fine crumbs. If you don't have a food processor, pop them in a sturdy, sealed food bag and crush them with a rolling pin.

In a medium bowl, combine the biscuit crumbs with the 120g of melted unsalted butter. Mix well until all the crumbs are evenly moistened and look like damp soil.

Take a 2.5-litre (or roughly 22x33 cm) casserole or baking dish. Press half of the buttery crumb mixture firmly and evenly into the bottom of the dish to create your base. Set aside.

Now for the filling. In a large bowl, using a stand mixer or an electric hand mixer, beat the 450g of softened cream cheese on medium speed until completely smooth and free of lumps, about 2 minutes.

Add the 200g of sifted icing sugar and 2 tsp of vanilla extract to the cream cheese. Beat again on low speed, then increase to medium, until everything is well combined and silky. Scrape down the sides of the bowl as needed.

In a separate, clean bowl, whip the 480ml of cold double cream until it forms stiff peaks. You can learn more about getting the perfect consistency from this helpful guide. Be careful not to over-whip it into butter!

Gently fold about a third of the whipped cream into the cream cheese mixture to lighten it. Then, add the remaining whipped cream and fold until just combined. What works best for me is using a large spatula in a gentle figure-of-eight motion to keep the air in the cream.

Spread the cream cheese mixture evenly over the biscuit base in your casserole dish. Smooth the top with the back of a spoon or an offset spatula.

Sprinkle the remaining half of the biscuit crumb mixture evenly over the top of the cream layer, covering it completely to create the top layer of "dirt."

Cover the dish with cling film and refrigerate for at least 4 hours, or ideally overnight. This chilling time is essential for the dessert to set properly.

Just before serving, decorate your Easter dirt cake. Arrange chocolate bunnies, sprinkle over mini eggs, and add patches of green coconut "grass" if you're using it. Serve chilled.
