Ingredients
For the Base:
- ½ cup unsalted butter, melted
- ¼ cup granulated sugar
- 5 tbsp cocoa powder
- 1 large egg, beaten
- 1 ¾ cups graham cracker crumbs
- ½ cup shredded sweetened coconut
- ½ cup chopped walnuts (optional)
For the Custard Filling:
- ½ cup unsalted butter, softened
- 2 cups powdered sugar
- 2 tbsp custard powder (or vanilla pudding mix as a substitute)
- 2–3 tbsp heavy cream or milk
Chocolate Topping:
- 4 oz semi-sweet chocolate, chopped
- 2 tbsp unsalted butter
Preparation
Step 1: Make the Base
- In a medium saucepan, melt the butter over medium-low heat. Stir in the sugar and cocoa powder until smooth.
- Gradually add the beaten egg, stirring constantly to avoid curdling, and cook until the mixture thickens slightly (about 1–2 minutes).
- Remove from heat and fold in the graham cracker crumbs, coconut, and walnuts (if using).
- Press the mixture firmly into the bottom of an ungreased 8×8-inch square baking dish. Refrigerate while preparing the filling.
Step 2: Prepare the Custard Filling
5. In a large mixing bowl, cream the butter until light and fluffy.
6. Add the powdered sugar and custard powder, mixing until combined. Gradually add heavy cream, one tablespoon at a time, until the filling is smooth and spreadable.
7. Spread the custard filling evenly over the chilled base. Return to the refrigerator to firm up for at least 20 minutes.
Step 3: Make the Chocolate Topping
8. In a heatproof bowl, melt the semi-sweet chocolate and butter together using a double boiler or in the microwave (in 20-second intervals, stirring frequently).
9. Let the chocolate cool slightly before pouring it over the custard layer. Smooth it with a spatula or tilt the pan to ensure even coverage.
Step 4: Chill and Slice
10. Refrigerate the assembled bars for at least 1 hour or until the chocolate sets completely.
11. Use a sharp knife to cut into squares. To prevent cracking, warm the knife under hot water and dry it before slicing.
Variations
- Peanut Butter Nanaimo Bars: Add 2 tablespoons of peanut butter to the custard filling for a nutty twist.
- Mint Chocolate Nanaimo Bars: Replace custard powder with 1 teaspoon of peppermint extract and add a drop of green food coloring for a minty version.
- Gluten-Free Nanaimo Bars: Substitute gluten-free graham crackers for the base.
Cooking Notes
- Custard Powder Substitute: If you can’t find custard powder, use vanilla pudding mix or cornstarch with a dash of vanilla extract for a similar flavor.
- Storage: Store Nanaimo Bars in an airtight container in the refrigerator for up to 5 days or freeze for up to 2 months.
Serving Suggestions
- Serve Nanaimo Bars chilled for a firm texture, or let them sit at room temperature for a softer bite.
- Pair with a hot cup of coffee or tea for an indulgent treat.
Tips
- Press the Base Firmly: Use the back of a spoon to compact the graham cracker mixture for a sturdy foundation.
- Even Chocolate Topping: Let the melted chocolate cool slightly to prevent it from melting the custard layer when pouring.
- Perfect Slices: Cut the bars while they are chilled but not overly hard for clean, sharp edges.
