Cocoa Graham Coconut Layers with Custard and Chocolate

Introduction

These bars stack a cocoa-graham-coconut base, a butter custard middle, and a thin chocolate top in an 8 x 8-inch pan. The stovetop work is brief, but the layers need time in the refrigerator to firm up, so this fits well as a make-ahead dessert for slicing into small squares.

Recipe Details

• Prep Time: 20 minutes
• Cook Time: 10 minutes
• Total Time: 30 minutes
• Servings: 16 squares

Ingredients

Bottom layer

• ½ cup unsalted butter (European style cultured)
• ¼ cup white granulated sugar
• 5 tbsp cocoa
• 1 egg beaten
• 1¼ cups graham wafer crumbs
• ½ cups finely-chopped almonds
• 1 cup coconut

Middle layer

• ½ cup unsalted butter
• 2 tbsp and 2 tsp cream
• 2 tbsp vanilla custard powder
• 2 cups icing sugar

Top layer

• 4 squares (4 oz) semi-sweet chocolate
• 2 tbsp unsalted butter

Instructions

Bottom layer

1. Melt first 3 ingredients in top of double boiler.
2. Add egg and stir to cook and thicken.
3. Remove from heat. Stir in crumbs, coconut, and nuts.
4. Press firmly into an ungreased 8 x 8-inch cake pan.

Middle layer

1. Cream butter, cream, custard powder, and icing sugar together well. Beat until light.
2. Spread over bottom layer.

Top layer

1. Melt chocolate and butter over low heat. Cool.
2. Once cool, but still liquid, pour over second layer and chill in refrigerator.
3. Once set, cut into squares and serve. Enjoy.

Variations

• Swap the finely-chopped almonds for pecans or walnuts if you want a softer crunch and a slightly richer nut flavor.
• Replace the semi-sweet chocolate in the top layer with dark chocolate for a firmer finish and less sweetness.
• Use digestive biscuit crumbs in place of the graham wafer crumbs if you want a more buttery, less honeyed base.
• Toast the coconut before stirring it into the bottom layer for a deeper flavor and a slightly drier, chewier texture.

Tips for Success

• Stir the egg into the cocoa mixture as soon as it goes in and keep the heat gentle so it thickens instead of scrambling.
• Press the bottom layer firmly into the ungreased 8 x 8-inch pan so the bars hold together cleanly when cut.
• Beat the middle layer until light; if you stop early, it can spread unevenly and feel dense.
• Let the chocolate topping cool until it is still pourable but no longer warm, or it can soften the middle layer.
• Chill the pan until the top is fully set before cutting, then use a warm knife for cleaner squares.

Storage and Reheating

Store the bars in an airtight container in the refrigerator for up to 5 days. Separate layers with parchment if you stack them.

Freeze in a freezer-safe container for up to 2 months. Thaw in the refrigerator overnight before serving.

These are meant to be served chilled or slightly cool, so reheating is not necessary. If you want a softer bite, let the squares sit at room temperature for 5 to 10 minutes before serving.

FAQ

Do you need a double boiler for the bottom layer?

No. You can set a heatproof bowl over a saucepan of barely simmering water and use that in the same way.

How long should you chill the bars before cutting them?

Plan on at least 1 to 2 hours, or until the chocolate top is firm and the middle layer no longer shifts when you move the pan.

Can you use a different nut instead of almonds?

Yes. Pecans or walnuts work well and keep the same structure, though the flavor will be a little richer and less neutral.

Why is the middle layer too soft to spread neatly?

The butter may be too warm, or the mixture may need more beating. Chill it for a few minutes, then beat again until it looks lighter and holds its shape better.
