What can we use instead of hazelnut spread or heavy cream if they're hard to find?

If you don't have hazelnut spread, substitute peanut or almond butter in the step 'put the chocolate chips and hazelnut spread into a heatproof bowl', and if heavy cream is unavailable, heat full-fat coconut milk until steaming before pouring over the chocolate.

My crust keeps crumbling or stays soggy after baking — what should we do?

If the crumb crust doesn't hold when pressed into the 9-inch tart pan or feels soggy after 'ask an adult to bake the crust in the oven for 8–10 minutes', add another tablespoon of melted butter, press firmly along the bottom and sides, and bake 3–5 minutes more to set.

How can I adapt this activity for different ages?

For toddlers let them crush the cookies in the zip-top bag and press crumbs into the pan while an adult handles all oven and hot-cream steps, and for older kids let them toast the hazelnuts, heat the cream with supervision, chop the cooled nuts, and smooth the silky filling.

How can we personalize or make the tart fancier?

After you 'pour the silky filling into the cooled crust', swirl an extra tablespoon of hazelnut spread through the chocolate with a toothpick, sprinkle the chopped toasted hazelnuts on top, and finish with a pinch of flaky sea salt or cocoa powder for extra flavor.

How do you make a silky chocolate hazelnut tart?

To make a silky chocolate hazelnut tart, start by preheating the oven to 350°F (175°C). Make a simple crust by crushing biscuits and mixing with melted butter, pressing into a tart pan, and blind-baking briefly until set. Heat cream until steaming, pour over chopped dark chocolate and a spoonful of chocolate-hazelnut spread, stir until smooth and glossy. Pour filling into the cooled crust, chill until firm, then top with toasted hazelnuts. Always have an adult handle the oven and chopping.

What materials do I need to make a silky chocolate hazelnut tart?

You'll need: Ingredients — about 200g crushed cookies or 1 batch shortcrust pastry, 75g melted butter, 200g good dark chocolate, 200ml heavy cream, 2–3 tablespoons chocolate-hazelnut spread or hazelnut paste, a pinch of salt, and 1 cup toasted hazelnuts for topping. Tools — tart pan, mixing bowls, saucepan, heatproof bowl for melting chocolate, whisk or spatula, food processor or rolling pin for crushing, baking tray, oven mitts, and a sharp knife (adult use only).

What ages is making a silky chocolate hazelnut tart suitable for?

This activity suits many ages with adult supervision. Toddlers (2–4) can explore textures, pour dry ingredients, and press crust pieces. Ages 5–8 can measure, mix, press a crust, and help pour filling while an adult handles hot tasks. Ages 9–12 can learn to heat cream and stir chocolate with close adult oversight. Teens 13+ can do most steps independently but an adult should still manage oven baking and knife work.

What safety tips or variations should I consider when making a silky chocolate hazelnut tart?

Safety first: always supervise oven use and chopping — adults should toast nuts, handle knives, and remove hot pans. Keep children at a safe distance when boiling or melting. For allergies, swap hazelnuts for toasted almonds or sunflower seeds, and use dairy-free cream and chocolate for lactose-free versions. Variations: make mini tartlets, add sea salt or orange zest to the filling, or use a gluten-free crust to include more family members.
