No Bake Dark Chocolate Tart Ingredients

The tart is made in two parts: a buttery chocolate biscuit crust and a smooth dark chocolate ganache filling. Both are quick to prepare but need time to chill, so plan ahead for the chilling time.

Buttery Chocolate Biscuit Crust

The crust is a straightforward mix of finely crushed chocolate biscuits, vanilla, and melted unsalted butter. Press the mixture into a rectangular tart pan and chill until firm. Chilling in the refrigerator for a couple of hours or overnight gives the best texture.

Dark Chocolate Ganache Filling

The ganache is made from dark chocolate (70% cacao suggested), heavy whipping cream, honey, and softened unsalted butter. The warm cream melts the chocolate into a glossy, creamy filling. Pour the ganache into the chilled crust, smooth the surface, and chill for several hours until set.

Helpful Tips Before Starting

Quick notes to ensure smooth preparation and a clean presentation:

  • Use a 14″ rectangular tart pan (or a pan of similar capacity) to achieve the same depth and slice yield.
  • If you prefer, choose darker or milk chocolate biscuits for the crust—use what you enjoy most.
  • Pay attention to butter temperature: the crust requires melted butter, the ganache needs softened (room-temperature) butter—not melted.
  • Chill the crust 30 minutes in the freezer or 1–2 hours in the refrigerator before filling the tart.
  • After pouring the ganache, chill the tart for 3–4 hours or overnight for best results.
  • For clean slices, run a knife under very hot water, wipe dry, then slice. Repeat heating and wiping between cuts for neat edges.

Recommended Baking Tools

A food processor for crushing the biscuits, a 14″ rectangular tart pan (or similar), a medium heatproof bowl for the chocolate, and a small saucepan to heat the cream will make the process easier and more consistent.

This No Bake Dark Chocolate Tart has a buttery chocolate biscuit crust filled with decadent ganache and finished with cookie crumbs. Easy to make and incredibly satisfying.

Ingredients

Buttery chocolate biscuit crust

  • 17.6 oz chocolate biscuits (finely crushed)
  • 1 tsp vanilla extract
  • 6 tbsp unsalted butter, melted

Dark chocolate ganache filling

  • 12.25 oz dark chocolate (70% cacao suggested)
  • 1 1/4 cup heavy whipping cream
  • 1 tbsp honey
  • 6 tbsp unsalted butter, softened to room temperature

Instructions

Buttery chocolate biscuit crust

  • Pulse the biscuits in a food processor until finely ground. Add vanilla and melted butter, then pulse or stir until the mixture holds together.
  • Press the mixture into the bottom and up the sides of a rectangular tart pan. Use the bottom of a measuring cup to level and compress the crust.
  • Chill the crust in the freezer for at least 30 minutes or in the refrigerator for 1–2 hours (or overnight) until firm.

Dark chocolate ganache filling

  • Place chopped dark chocolate in a heatproof bowl. Add honey and softened butter but do not stir yet.
  • Heat the cream in a small saucepan until it just boils. Remove from heat and pour the hot cream over the chocolate, butter, and honey. Cover loosely and let sit 2–3 minutes.
  • Uncover and stir until smooth and glossy. If necessary, warm briefly in the microwave for 15–30 seconds and stir until fully melted.

Assembling the tart

  • Pour the ganache into the chilled crust and smooth the top with an offset spatula. Sprinkle reserved cookie crumbs on top if desired.
  • Refrigerate the tart for 3–4 hours or overnight until set. For clean slices, warm a knife under hot water, dry it, and slice, repeating between cuts for neat edges.

Notes

  • If you don’t have the specific biscuit brand, any sturdy chocolate biscuit or cookie will work for the crust.
  • Softened butter for the ganache should be room temperature—soft but not melted—to create a smooth, glossy finish.
  • Chill times are important: allow the crust and ganache sufficient time to firm for the best texture and clean slices.
