Ingredients

Scale

Cookie Dough

  • 1 cup all-purpose flour
  • 1/2 cup graham crumbs
  • 1/4 cup cocoa powder
  • 1 tsp baking powder
  • 1/2 tsp salt
  • 1/2 cup butter, softened
  • 3/4 cup packed golden sugar
  • 1 large egg
  • 1 tsp vanilla extract
  • 3/4 cup shredded coconut (sweetened or unsweetened)
  • 1/3 cup finely chopped walnuts or pecans (optional)

Filling

  • 1/4 cup butter, softened
  • 1 1/4 cups icing sugar
  • 2 Tbsp Bird’s Custard Powder
  • 2 Tbsp cream, milk or coconut milk (+ more if needed)
  • 1/2 tsp vanilla extract (optional)

Drizzle

  • 1/2 cup chopped chocolate or chocolate chips
  • 1 Tbsp butter or coconut oil

Instructions

  1. Preheat and prepare dry ingredients: Preheat your oven to 350°F (175°C). In a medium bowl, whisk together the all-purpose flour, graham crumbs, cocoa powder, baking powder, and salt until well combined.
  2. Make the cookie dough: In a large bowl, beat the softened butter and golden sugar for 3-4 minutes until the mixture is fluffy. Beat in the egg and vanilla extract. Using low speed or a spatula, gently fold in the dry ingredients along with the shredded coconut and chopped nuts if using, until evenly mixed.
  3. Form cookies and create indentations: Roll the dough into walnut-sized balls and place them spaced a couple of inches apart on a parchment-lined baking sheet. Use your thumb or the handle of a wooden spoon to press an indentation into the center of each cookie ball, forming a little well for the filling.
  4. Bake and cool: Bake the cookies in the preheated oven for approximately 14 minutes, or until they are just set. Once baked, transfer the cookies to a wire rack to cool completely before adding the filling.
  5. Prepare the custard filling: Beat the softened butter, icing sugar, Bird’s Custard Powder, cream (or milk/coconut milk), and vanilla extract (if using) together until smooth and fluffy. Adjust the consistency by adding a little more cream or icing sugar to achieve a soft, spreadable frosting. Fill a piping bag fitted with a 1/2-inch plain tip or use a zip-lock bag with a corner cut off, then pipe the filling into the indentations of each cooled cookie.
  6. Melt the chocolate drizzle: In a microwave-safe bowl, melt the chopped chocolate and butter (or coconut oil) in 10-second increments, stirring between each until the mixture is smooth.
  7. Apply chocolate topping: Dip each filled cookie halfway into the melted chocolate to coat the filling, or alternatively, drizzle the chocolate over the cookies using a fork. Place the cookies back on the baking sheets and allow the chocolate to set completely.
  8. Serve: Once the chocolate has hardened, your Nanaimo Bar Thumbprint Cookies are ready to serve. Enjoy these rich and indulgent treats with a cup of tea or coffee.

Notes

  • Use sweetened or unsweetened shredded coconut based on your preference.
  • Walnuts or pecans are optional but add a pleasant crunch and flavor.
  • Bird’s Custard Powder gives the frosting an authentic custard flavor; substitute with vanilla pudding mix if unavailable.
  • Be sure to cool cookies completely before adding frosting to prevent melting.
  • For a dairy-free version, substitute butter with coconut oil or vegan margarine and use coconut milk in the filling.
  • Store cookies in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
