Step-by-Step Instructions
1. Prepare the Oat Crust
Combine oats, walnuts, cocoa powder, maple syrup, melted coconut oil, vanilla extract, and salt in a food processor. Process until the mixture is finely ground and sticky. Press this mixture evenly into the bottom and up the sides of a 9-inch tart pan.
2. Bake the Crust
Bake your healthy baking crust in a preheated oven at 350°F (175°C) for 12-15 minutes, or until lightly golden. Allow it to cool completely on a wire rack while you prepare the filling.
3. Make the Dark Chocolate Filling
In a small saucepan over medium heat, gently warm the coconut milk and maple syrup until just simmering. Remove from heat and stir in the dark chocolate chips, vanilla extract, and a pinch of salt until smooth and glossy.
4. Assemble the Tart
Pour the prepared chocolate filling into the cooled oat crust. Gently tap the tart pan on the counter a few times to release any air bubbles. Sprinkle the roughly chopped walnuts evenly over the top of the filling.
5. Chill and Serve
Place the tart in the refrigerator for at least 1.5 hours, or until the filling is firm. This ensures a perfect set for your healthy baking recipe. Once firm, slice and serve.
Variation Ideas
- Add a sprinkle of sea salt flakes over the chocolate filling before chilling for a salted dark chocolate tart.
- Incorporate a tablespoon of orange zest into the filling for a citrusy twist.
- Top with fresh berries like raspberries or strawberries just before serving for added freshness.
- Mix a teaspoon of instant coffee granules into the filling for a mocha flavor.
Storage Instructions
Store your dark chocolate walnut tart in an airtight container in the refrigerator for up to 5 days. For the best texture, let it sit at room temperature for 10-15 minutes before serving if you prefer a slightly softer filling. Freezing is also an option; wrap slices tightly and store for up to 1 month. Thaw in the refrigerator overnight.
