Ingredients:
- 1 box (15.25 oz) White Cake Mix
- 1 cup (240ml) Water
- 1/2 cup (115g) Sour cream
- 3 Large Egg Whites
- 1/3 cup (80ml) Neutral Vegetable Oil
- 1 can (14 oz) Sweetened Condensed Milk
- 1/2 cup (120ml) Kahlua or coffee liqueur
- 1/4 cup (60ml) Premium Vodka
- 2 cups (480ml) Cold Heavy Whipping Cream
- 1/2 cup (60g) Powdered Sugar
- 1 tsp (5ml) Pure Vanilla Extract
Instructions:
- Preheat your oven to 350°F (180°C) and grease your 9x13 pan thoroughly. Note: Using a baker's spray with flour helps the cake edges release cleanly.
- Combine the cake mix, water, sour cream, egg whites, and oil in your mixer. Beat on low for 30 seconds, then medium for 2 minutes until the batter is silky and pale.
- Pour into the pan and bake for 25-30 minutes. Check at 25 minutes; the top should spring back when touched.
- Let the cake sit on a wire rack for exactly 10 minutes. Note: Poking a hot cake leads to gumminess, while a cold cake won't absorb as well.
- Using your wooden spoon handle, poke holes about 1 inch apart all over the cake. Go about 3/4 of the way down, not all the way to the bottom.
- Whisk the sweetened condensed milk, Kahlua, and vodka together in a bowl until perfectly smooth.
- Slowly pour the milk mixture over the warm cake, aiming for the holes. Watch the liquid vanish into the sponge; it’s incredibly satisfying.
- Cover and refrigerate for at least 4 hours (overnight is better). Note: This allows the alcohol to mellow and the milk to set.
- In a chilled bowl, beat the heavy cream, powdered sugar, and vanilla until stiff peaks form and it looks like a thick cloud.
- Spread the cream over the cold cake and garnish with a dusting of cocoa powder or chocolate shavings. Serve cold for the most refreshing experience.
