Ingredients Breakdown
- Unsalted Butter: Provides the essential fat for the base, buttercream, caramel, and ganache, ensuring a rich mouthfeel and structural stability.
- Granulated Sugar: Acts as the primary sweetener and contributes to the structural formation of both the chocolate base and the caramel layer.
- Cocoa Powder: Delivers that deep, intense chocolate foundation that anchors the sweetness of the other layers.
- Egg: Acts as a binding agent for the base layer, ensuring it holds together firmly when pressed into the pan.
- Gluten-Free Graham Cracker Crumbs: Replaces traditional wheat-based crumbs to provide the necessary structure and “graham” flavor to the bottom layer.
- Shredded Coconut: Adds a delightful chewiness and subtle nutty flavor that is a hallmark of the authentic Nanaimo bar.
- Sliced Almonds: Introduces a contrasting crunch and nutty complexity to the chocolate base.
- Milk Powder: Replaces professional custard powder, providing the essential dairy richness for the buttercream filling.
- Cornstarch: Helps thicken the custard layer, ensuring it remains firm enough to slice neatly.
- Vanilla Extract: Enhances the overall flavor profile by adding aromatic depth to the buttercream.
- Heavy Cream: Essential for achieving a smooth, spreadable consistency in both the custard and the caramel layers.
- Fleur de Sel: Elevates the caramel layer by cutting through the sweetness and adding a sophisticated salty finish.
- Dark Chocolate: Provides a rich, semi-sweet finish that balances the sugar content of the lower layers.
Tips To Get Your Recipe Right
- Parchment is Paramount: Always line your square pan with parchment paper, leaving an overhang on the sides. This is the only way to cleanly lift your bars out once they are set.
- Chill Between Layers: Patience is key. Ensure each layer is properly chilled in the refrigerator before moving to the next; this prevents the layers from bleeding into one another.
- The Perfect Score: Because the chocolate ganache can crack when sliced cold, remove the bars from the fridge and let them sit for 20–30 minutes. Use a sharp knife that has been run under hot water to score the top before cutting through the bottom.
- Quality Caramel Control: If making your own, keep a close eye on the sugar color. You are aiming for a deep amber hue; once you add the butter and cream, ensure it is smooth and emulsified.
- Mastering the Buttercream: When adding the powdered sugar to the buttercream, do it in stages. This ensures a smooth, lump-free consistency that is easy to spread.
Storage Tips
- Refrigeration: These bars are best kept in an airtight container in the refrigerator for up to one week, as the layers stay firmer when chilled.
- Freezing: For long-term storage, wrap the bars tightly in plastic wrap and place them in a freezer-safe container for up to three months.
- Thawing: If frozen, allow the bars to come to temperature for a few minutes before serving, or enjoy them slightly chilled for a firm, refreshing treat.
FAQs
Can I use store-bought caramel for this recipe?
Yes, you can. Ensure you select a high-quality, thick salted caramel sauce that firms up in the refrigerator, rather than a thin drizzling sauce, to keep the layers distinct.
Why is there turmeric in the buttercream?
The turmeric is optional and used solely to replicate the classic yellow hue of traditional custard powder. It does not affect the flavor significantly.
Can I substitute milk powder if I don’t have it?
If you don’t have milk powder, you can omit it. Alternatively, if you have custard powder on hand, you can replace the milk powder, cornstarch, and turmeric with 1½ teaspoons of custard powder.
How do I prevent the chocolate layer from cracking?
The secret is in the temperature. Always allow the bars to rest at room temperature for 20–30 minutes before slicing, and use a warm, sharp knife to gently score the top.
Are these bars truly gluten-free?
They are, provided you use certified gluten-free graham cracker crumbs. Always check your labels to ensure no wheat-based ingredients are present in your crumbs or other additions.

Ingredients
- Bottom Layer
1 cup gluten-free graham cracker crumbs
1 cup / 65g shredded coconut
½ cup / 45g sliced almonds
½ cup / 113g unsalted butter
¼ cup / 50g granulated sugar
5 tablespoons cocoa powder
1 large egg, beaten
- Custard Buttercream
1¼ cups / 150g powdered sugar
¼ cup / 56g unsalted butter, softened
1½ tablespoons heavy cream
¾ teaspoon / 6g milk powder
¾ teaspoon / 6g cornstarch
¼ teaspoon vanilla extract
Pinch of salt
Pinch of turmeric (optional)
- Salted Caramel
½ cup / 100g granulated sugar
3 tablespoons / 42.5g unsalted butter, cubed
¼ cup / 60ml heavy cream
½ teaspoon fleur de sel
- Chocolate Ganache
4oz / 120g chopped dark chocolate
1 tablespoon / 14g unsalted butter
Directions
- Prepare the Base: Grease an 8x8-inch square pan and line it with parchment paper.
- Cook the Base Layer: Melt the butter, sugar, and cocoa powder in a double boiler until smooth. Remove from heat and whisk in the beaten egg until fully combined. Fold in the gluten-free graham cracker crumbs, shredded coconut, and sliced almonds. Press the mixture firmly into your prepared pan and chill in the refrigerator.
- Create the Custard Buttercream: In a medium bowl, cream the softened butter until fluffy. Beat in the milk powder, cornstarch, salt, turmeric, and vanilla extract. Gradually add the powdered sugar in three batches, beating thoroughly after each. Finish by beating in the heavy cream. Spread this mixture evenly over the chilled base and return the pan to the refrigerator.
- Prepare the Salted Caramel: Spread the sugar in an even layer in a nonstick pan. Heat over medium-high, swirling occasionally as it melts, until it reaches a deep amber color (approx. 350°F/175°C). Remove from heat, stir in the butter until melted, then stir in the heavy cream. Once combined, mix in the fleur de sel. Let the caramel cool to room temperature, then spread over the buttercream layer. Chill again.
- Finish with Ganache: Melt the dark chocolate and butter together in a double boiler. Stir until smooth, allow to cool slightly, and spread over the caramel layer. Chill for 30 to 60 minutes before scoring and slicing.
