Step-by-step: Make the Berry Midnight Velvet Slice – Indigo Temptation
Ingredients:
- 1 1⁄2 cups (190 g) flour
- 3⁄4 cup (75 g) cocoa powder
- 1 1⁄2 cups (300 g) granulated sugar
- 1 teaspoon baking powder
- 1⁄2 teaspoon baking soda
- 1⁄2 teaspoon salt
- 2 large eggs
- 3⁄4 cup (180 ml) milk
- 1⁄2 cup (120 ml) vegetable oil
- 3⁄4 cup (180 ml) hot water or coffee
- 1 teaspoon vanilla extract
Vanilla cream:
- 400 ml milk
- 3 tablespoons cornstarch
- 1 tablespoon flour
- 1⁄2 cup (100 g) granulated sugar
- 1 teaspoon vanilla extract or 1 vanilla bean, scraped
- 1 tablespoon butter
- 100 ml cream (chilled, added last)
Berry layer:
- 150 g blueberries
- 100 g blackberries
- 2 tablespoons sugar
- 1 teaspoon lemon juice
- 1 teaspoon cornstarch (dissolved in a little water)
Mirror glaze:
- 150 g powdered sugar
- 100 ml water
- 100 g glucose syrup or honey
- 75 g cocoa powder
- 100 ml cream
- 5 g gelatin (1 sheet or 1 teaspoon powder)
Directions:
- Cake: Preheat the oven to 350°F (175°C). Whisk the flour, cocoa, sugar, baking powder, baking soda, and salt in a bowl. Add the eggs, milk, oil, and vanilla. Stir until smooth. Gradually add the hot water or coffee and mix until combined. Divide batter into two equal pans. Bake for 25–30 minutes or until a toothpick comes out clean. Cool completely.
- Berry Layer: In a small saucepan, heat the blueberries, blackberries, sugar, and lemon juice over medium heat. When the fruit releases juices, stir in the dissolved cornstarch. Cook until the mix thickens. Remove from heat and cool.
- Vanilla Cream: In a saucepan, combine the milk, cornstarch, flour, sugar, and vanilla. Cook over medium heat, stirring, until thick. Remove from heat and stir in the butter. Cool to room temperature, then fold in the chilled cream and whisk until smooth.
- Mirror Glaze: Soak gelatin in cold water (if using sheet) or sprinkle powdered gelatin into a little cold water. In a saucepan, heat the powdered sugar, water, glucose (or honey), and cocoa powder. Bring to a boil, then add the cream. Remove from heat. When the mixture cools to about 60°C (140°F), stir in the dissolved gelatin until melted. Strain to remove lumps.
- Layering: On a serving base, layer one cake layer, spread half the vanilla cream, then the cooled berry layer, then the second cake layer, and top with the remaining vanilla cream. Chill in the fridge for 1–2 hours to set.
- Decoration: Pour the warm mirror glaze over the chilled cake to cover the top smoothly. Once the glaze sets, decorate with fresh blueberries as “blueberry pearls.” Serve cold.
Ingredients you’ll want ready
Gather the ingredients listed above before you start. Measure the dry ingredients first. If you like a slightly different flavor, you might swap coffee for part of the hot water to deepen the chocolate notes. For another berry twist, check a red velvet strawberry cheesecake for pairing ideas.
How to serve the Berry Midnight Velvet Slice
Cut the cake into neat slices with a hot, dry knife for a clean glaze cut. Serve chilled or just slightly cool from the fridge. A small dollop of extra whipped cream and a few fresh berries on the side make each plate look inviting. For a light dessert menu, consider a simple scoop of ice cream alongside.
How to store the remaining slice
Store the cake covered in the refrigerator for up to 3–4 days. Keep it in an airtight container or cover the platter tightly to prevent it from absorbing fridge odors. If you need to freeze, wrap individual slices in plastic wrap and place them in a freezer-safe container for up to 1 month. Thaw overnight in the fridge before serving.
Pro tips for the best result
- Use hot coffee instead of water for a richer chocolate flavor.
- Chill the cake well before glazing; the glaze sets better on cold cake.
- Strain the glaze to avoid lumps and get a smooth shine.
- If the berry layer is too runny, add a touch more dissolved cornstarch and heat gently until thick.
- For cleaner slices, wipe the knife between cuts.
Simple variations to try
- Swap berries: Use raspberries or a mixed berry blend.
- Fruit compote: Add a spoon of orange liqueur to the berry mix for depth.
- Chocolate twist: Fold chocolate chips into the batter for texture.
- Lighter version: Replace some oil with applesauce for a lower-fat cake.

Common questions about the Berry Midnight Velvet Slice
Q: Can I make this ahead of time?
A: Yes. Make the cake and layers a day ahead, assemble, and keep refrigerated. Glaze on the day you serve for best shine.
Q: Can I use frozen berries for the berry layer?
A: Yes. Thaw them first and drain excess liquid, then cook as directed. You may need a touch more cornstarch if they are watery.
Q: Is there a substitute for gelatin in the mirror glaze?
A: You can use agar-agar, but follow package instructions and note that texture may differ slightly. Gelatin gives the smoothest, glossy finish.
Q: How do I fix a glaze with bubbles?
A: Let it sit for a minute and gently tap the pan to bring bubbles to the surface, then skim or strain the glaze before pouring.
