For the cake:

2½ cups (313 g) all-purpose flour

2½ tsp (13 g) baking powder

½ tsp (3 g) baking soda

1 tsp (6 g) salt

1¾ cups (350 g) Redpath® Granulated Sugar, divided (¾ cup and 1 cup)

¾ cup (117 g) black sesame seeds

1 cup (227 g) unsalted butter

3 large eggs, room temperature

1 tsp (5 ml) vanilla extract

1 cup (240 ml) milk

Black food colouring, optional

For the glaze:

2 cups (340 g) black seedless grapes

¼ cup (60 ml) water

1 tsp (2 g) lemon zest

2 cups (240 g) Redpath® Icing Sugar

⅛ tsp (1 g) salt


For the cake:

Step 1
Preheat oven to 350°F (180°C). Using a pastry brush, generously grease a 10 cup (2.5 litre) bundt pan with butter, taking care to reach all the creases.

Step 2
In a large bowl, sift together the flour, baking powder, baking soda, and salt; set aside.

Step 3
In a blender or food processor, blend ¾ cup (150 grams) of Redpath® Granulated Sugar with the black sesame seeds to a powder consistency. Whisk into the flour mixture.

Step 4
Using an electric mixer or in the bowl of a stand mixer fitted with the paddle attachment beat the butter and remaining 1 cup (200 g) of Redpath® Granulated Sugar on medium speed until pale and fluffy; 4 minutes.

Step 5
Add the eggs one at a time, allowing each egg to fully incorporate before adding the next.

Step 6
Mix in the vanilla extract.

Step 7
Reduce speed to low and alternate adding ⅓ of the flour mixture to the butter mixture, with ½ the milk, scraping down the sides of the bowl as necessary, until all ingredients are combined.

Step 8
For a more dramatic black cake colour, add a few drops of black food colour to the batter and fold in.

Step 9
Transfer the batter to the prepared pan and tap a few times on the counter to release any large air bubbles.

Step 10
Bake until a skewer inserted into the centre of the cake emerges clean and the edges of the cake start to release from the pan; 45 to 50 minutes.

Step 11
Allow cake to cool in the pan for 10 minutes before inverting onto a cooling rack and removing the pan. Allow cake to cool completely before glazing.

For the glaze:

Step 1
Place the grapes, water and lemon zest in a small pot over medium heat and bring to a simmer. Mash the grapes to release juices and allow mixture to simmer until reduced to ½ cup; about 15 minutes.

Step 2
Allow grape mixture to cool for 10 minutes. Transfer to a blender and add the Redpath® Icing sugar. Blend until smooth; 3 to 4 minutes.

Step 3
Pour glaze over cake and allow to dry for 15 minutes before serving.

Chef's Tips

*Black sesame seeds can be found in most Asian grocery stores, the international section of large grocery chains or natural foods stores.

*If black grapes are unavailable, use the darkest colour grapes available. The purple hue can also be boosted with a few drops of food colouring, if desired.
