Let’s dive into the ingredients you’ll need to create this masterpiece!

Ingredients You’ll Need

• 200g (1 ⅔ cups) All-Purpose Flour: We’re using all-purpose flour as the base for our cake, providing structure and a tender crumb. Sifting the flour is crucial to remove any lumps and ensure a light and airy texture.
• 60g (½ cup) Unsweetened Cocoa Powder: This provides the deep, rich chocolate flavor that complements the strawberries beautifully. Opt for a high-quality cocoa powder for the best results.
• 300g (1 ½ cups) Granulated Sugar: Granulated sugar sweetens the cake and contributes to its moistness. It also helps with browning and creating a tender texture.
• 2 tsp (10g) Baking Powder: Baking powder is a leavening agent that helps the cake rise, creating a light and fluffy texture.
• ½ tsp (2.5g) Baking Soda: Another leavening agent, baking soda reacts with the acidity in the recipe (like cocoa powder) to provide extra lift.
• ¼ tsp (1.5g) Salt: Salt enhances the flavors of the other ingredients and balances the sweetness.
• 2 Large Eggs: Eggs bind the ingredients together, add richness, and contribute to the cake’s structure.
• 240ml (1 cup) Whole Milk: Whole milk provides moisture and richness to the cake.
• 115g (½ cup) Unsalted Butter: Melted butter adds moisture, tenderness, and flavor. Make sure it’s cooled slightly before adding it to the wet ingredients to prevent cooking the eggs.
• 10ml (2 tsp) Alcohol-Free Vanilla Extract: Vanilla extract enhances the overall flavor profile of the cake, adding warmth and complexity.
• 120ml (½ cup) Hot Water: Hot water helps to bloom the cocoa powder, intensifying its chocolate flavor.
• 150g (5.3oz) White Chocolate: Finely chopped white chocolate is the star of our mousse swirl, adding a creamy sweetness. Use a good quality white chocolate for the best flavor and melting consistency.
• 60ml (¼ cup) Full-Fat Coconut Milk: Full-fat coconut milk adds richness and a subtle tropical flavor to the white chocolate mousse.
• 30ml (2 Tbsp) Heavy Cream: Heavy cream is whipped into the cooled white chocolate mixture to create a light and airy mousse texture.
• 5ml (1 tsp) Fresh Lemon Juice (for mousse): A touch of lemon juice brightens the white chocolate mousse and balances the sweetness.
• Pinch of Salt (for mousse): A pinch of salt enhances the flavors in the mousse.
• 300g (1 ¼ cups) Fresh Strawberries, Hulled: Fresh strawberries are essential for the vibrant glaze, providing a burst of fruity flavor.
• 80g (⅓ cup) Granulated Sugar (for glaze): Sugar sweetens the strawberry glaze.
• 15ml (1 Tbsp) Fresh Lemon Juice (for glaze): Lemon juice adds brightness and acidity to the glaze, balancing the sweetness of the strawberries.
• 5g (1 tsp) Fresh Basil Leaves, Finely Chopped (for glaze): Fresh basil adds a unique and refreshing herbal note to the strawberry glaze.
• Fresh Basil Leaves (for garnish): For a beautiful finishing touch.
• Extra White Chocolate, Shaved (for garnish): Adds a touch of elegance and extra white chocolate flavor.

Let’s Bake: Detailed Step-by-Step Instructions

1. Preheat and Prepare: Begin by preheating your oven to 180°C (350°F). This ensures even baking. Thoroughly grease a 9-inch round cake pan with butter or baking spray. Line the bottom with a circle of parchment paper – this is crucial for easy removal of the cake later.
2. Combine Dry Ingredients: In a large mixing bowl, whisk together the sifted all-purpose flour, unsweetened cocoa powder, granulated sugar, baking powder, baking soda, and salt. Sifting the flour and cocoa powder is important to prevent lumps and create a lighter texture. Whisking ensures everything is evenly distributed.
3. Combine Wet Ingredients: In a separate bowl, whisk together the large eggs, whole milk, melted and cooled unsalted butter, vanilla extract, and hot water. The hot water helps bloom the cocoa powder, intensifying its chocolate flavor. Ensure the butter is cooled to prevent cooking the eggs.
4. Combine Wet and Dry: Gently pour the wet ingredients into the bowl with the dry ingredients. Stir *just* until combined. Do not overmix! Overmixing develops the gluten in the flour, resulting in a tough cake. The batter will be quite thin – this is normal.
5. First Batter Layer: Spoon half of the batter into the prepared cake pan, spreading it evenly across the bottom. This forms the base layer of our earthquake cake.
6. Prepare the White Chocolate Mousse: This is where the magic happens! Melt the finely chopped white chocolate with the full-fat coconut milk and 1 tsp of lemon juice using a double boiler (or a heatproof bowl set over a simmering pot of water). Stir constantly until smooth and completely melted. Remove from heat and let it cool to room temperature. Once cooled, gently fold in the heavy cream and a pinch of salt until the mousse is light and airy. Be careful not to overfold, as this can deflate the mousse.
7. Mousse Swirl: Drop spoonfuls of the white chocolate mousse over the first layer of batter. Using a skewer or the tip of a knife, gently swirl the mousse into the batter, creating beautiful ribbons. Avoid over-swirling, as you want distinct ribbons, not a fully blended mixture.
8. Second Batter Layer & Bake: Pour the remaining batter over the top of the mousse-swirled layer, smoothing the surface with a spatula. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
9. Cooling Process: Allow the cake to cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely. Cooling in the pan prevents the cake from breaking apart.
10. Strawberry-Basil Glaze: While the cake cools, prepare the glaze. Combine the hulled fresh strawberries, 80g of granulated sugar, 1 tbsp of lemon juice, and the finely chopped fresh basil in a blender. Blend until completely smooth.
11. Simmer and Strain Glaze: Transfer the strawberry-basil mixture to a small saucepan and simmer gently for 5 minutes, stirring constantly, until slightly thickened. If you prefer a perfectly smooth glaze, strain it through a fine-mesh sieve to remove any seeds.
12. Glaze and Garnish: Once the cake is fully cooled, pour the warm strawberry-basil glaze over the top, allowing it to cascade down the sides. Let the glaze set for about 10 minutes. Finish by scattering a few fresh basil leaves and shaved white chocolate over the glaze for a beautiful presentation.

The Science Behind the ‘Earthquake’

The name ‘Earthquake Cake’ isn’t just for show! The unique texture comes from the combination of a thin batter and the pockets of mousse within. As the cake bakes, the batter sets around the mousse, creating a slightly unstable structure. When you cut into it, the cake tends to crumble and shift – hence the ‘earthquake’ effect. The hot water in the batter also contributes to this texture by creating steam during baking, resulting in a moist and tender crumb. The white chocolate mousse adds richness and a delightful contrast to the dark chocolate cake.

Strawberry and Basil: A Perfect Pairing

The combination of strawberries and basil might seem unusual, but it’s a classic pairing in culinary circles. Basil enhances the sweetness of the strawberries, adding a subtle peppery and herbaceous note that elevates the flavor profile. The lemon juice in both the mousse and the glaze brightens the flavors and prevents the glaze from being overly sweet. This glaze isn’t just about flavor; it also adds a beautiful vibrant color to the cake.

Tips for a Perfect Swirl

Achieving a beautiful swirl effect with the white chocolate mousse is easier than you think. The key is to work quickly and gently. Don’t overmix the mousse into the batter – you want distinct ribbons of white chocolate. Using a skewer or a thin knife allows for precise swirling without disturbing the batter too much. If you find the mousse is too thick to swirl easily, you can gently warm it for a few seconds to soften it slightly.

Storing Your Strawberry Earthquake Cake

This cake is best enjoyed fresh, but leftovers can be stored in an airtight container in the refrigerator for up to 3 days. The glaze may become slightly sticky as it sits, but the flavor will remain delicious. Allow the cake to come to room temperature before serving for the best texture.

Frequently Asked Questions

Can I use frozen strawberries for the glaze?

Yes, you can! Just be sure to thaw them completely and drain off any excess liquid before blending.

Can I substitute the white chocolate?

While white chocolate is key to the mousse’s flavor and texture, you could experiment with other flavors like raspberry or lemon, but the result will be different.

What if I don’t have a double boiler?

Use a heatproof bowl set over a simmering pot of water, ensuring the bottom of the bowl doesn’t touch the water.
