The result is a moist, flavorful cake with a creamy custard layer and a caramelized pineapple topping. It’s surprisingly easy to make, despite its impressive presentation, and requires no complicated techniques.

**Why is it called “Impossible Cake”?**

The name comes from the way the cake layers separate and rearrange themselves during baking. The batter is poured into the pan in a specific order, but as it bakes, the denser custard layer sinks to the bottom, while the lighter cake layer rises to the top. This seemingly “impossible” transformation is what makes this cake so unique and intriguing.

**Let’s get baking!**

## Ingredients:

**For the Caramel Topping:**

* 1/2 cup (100g) granulated sugar
* 1/4 cup (60ml) water
* 1 (20 oz) can crushed pineapple, undrained

**For the Cake Layer:**

* 1 cup (125g) all-purpose flour
* 1 cup (200g) granulated sugar
* 2 teaspoons baking powder
* 1/4 teaspoon salt
* 1/2 cup (120ml) milk
* 1/4 cup (60ml) vegetable oil
* 1 large egg
* 1 teaspoon vanilla extract

**For the Custard Layer:**

* 1 (14 oz) can sweetened condensed milk
* 1 (12 oz) can evaporated milk
* 4 large eggs
* 1/4 cup (60ml) lime juice, freshly squeezed (from about 2-3 limes)
* 1 teaspoon lime zest

## Equipment:

* 9-inch round baking pan
* Mixing bowls
* Whisk
* Rubber spatula
* Measuring cups and spoons
* Saucepan (for caramel)
* Oven
* Cooling rack

## Instructions:

**Step 1: Prepare the Caramel Topping**

1. In a medium saucepan, combine the granulated sugar and water. Cook over medium heat, stirring occasionally, until the sugar dissolves and the mixture comes to a boil.
2. Continue cooking, without stirring, until the caramel turns a golden amber color. This will take about 5-7 minutes. Watch it carefully to prevent burning. If it starts to burn, remove it from the heat immediately.
3. Remove the saucepan from the heat and carefully pour the crushed pineapple (with its juice) into the caramel. The mixture will bubble and steam, so be cautious.
4. Stir to combine the pineapple and caramel.
5. Pour the pineapple mixture into the bottom of the 9-inch round baking pan, spreading it evenly.

**Step 2: Make the Cake Layer**

1. In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt.
2. In a separate bowl, combine the milk, oil, egg, and vanilla extract. Whisk until well combined.
3. Pour the wet ingredients into the dry ingredients and stir until just combined. Be careful not to overmix.

**Step 3: Make the Custard Layer**

1. In a blender or food processor, combine the sweetened condensed milk, evaporated milk, eggs, lime juice, and lime zest.
2. Blend until smooth and creamy.

**Step 4: Assemble and Bake the Cake**

1. Gently pour the cake batter over the pineapple layer in the baking pan. Try to spread it evenly.
2. Carefully pour the custard mixture over the cake batter. Again, spread it evenly.
3. Cover the baking pan tightly with aluminum foil. This will prevent the top from browning too quickly and help the cake bake evenly.
4. Place the baking pan inside a larger baking pan or roasting pan. This will create a water bath, which will help to keep the cake moist and prevent it from cracking.
5. Pour hot water into the outer pan, filling it about halfway up the sides of the cake pan. Be careful not to splash any water into the cake batter.
6. Bake in a preheated oven at 350°F (175°C) for 60-75 minutes, or until a toothpick inserted into the center of the cake comes out clean. The cake should be set but still slightly wobbly.
7. Remove the cake from the water bath and carefully remove the aluminum foil.
8. Let the cake cool completely in the pan on a wire rack. This is important for the layers to set properly. This will take at least 2-3 hours, or even better, overnight.

**Step 5: Invert and Serve**

1. Once the cake is completely cooled, run a thin knife or spatula around the edges of the pan to loosen the cake.
2. Place a serving plate over the top of the baking pan.
3. Carefully invert the cake onto the serving plate. The pineapple topping should now be on top.
4. Slice and serve. Enjoy!

## Tips for Success:

* **Don’t overmix the cake batter:** Overmixing can result in a tough cake. Mix until just combined.
* **Use fresh lime juice:** Fresh lime juice will give the custard layer a brighter, more vibrant flavor. Bottled lime juice can be used in a pinch, but it won’t have the same fresh taste.
* **Zest the lime before juicing:** It’s easier to zest the lime before you juice it.
* **Ensure the water bath is hot:** Using hot water in the water bath will help the cake bake evenly.
* **Cool the cake completely:** Cooling the cake completely is essential for the layers to set properly. Don’t be tempted to invert it before it’s fully cooled.
* **If the caramel is too hard after inverting:** If the caramel is too hard after inverting, you can gently warm the bottom of the pan with a kitchen torch or by placing it over a low burner for a few seconds. This will help to soften the caramel and make it easier to slice.
* **Variations:** Experiment with other tropical fruits, such as mango or coconut. You can also add a splash of rum or coconut extract to the cake batter or custard layer for an extra layer of flavor.
* **Preventing a soggy bottom:** Ensure the water bath doesn’t overflow into the cake pan. A tight seal with aluminum foil is crucial. If you’re concerned, you can also place a kitchen towel underneath the cake pan inside the water bath to absorb any potential leaks.
* **Adjusting sweetness:** If you prefer a less sweet cake, you can reduce the amount of sugar in the cake batter or custard layer. You can also use a sugar substitute.

## Serving Suggestions:

* Serve the cake chilled or at room temperature.
* Garnish with fresh lime wedges or mint sprigs.
* Serve with a scoop of vanilla ice cream or whipped cream.
* Pair with a tropical cocktail for a complete tropical experience.

## Storage Instructions:

* Store the cake in an airtight container in the refrigerator for up to 3 days.
* The cake can also be frozen for up to 2 months. Thaw in the refrigerator overnight before serving.

## Troubleshooting:

* **Cake is too dry:** Make sure you’re not overbaking the cake. Also, ensure the water bath is filled with enough water. A dry cake could also indicate that the batter was overmixed.
* **Cake is not setting:** The cake may not be fully baked. Bake for a longer time, checking every 5-10 minutes. Also, ensure the oven temperature is accurate. Inadequate cooling can also result in an unset cake.
* **Custard layer is too watery:** This could be due to not baking the cake long enough or using too much liquid in the custard mixture. Ensure you’re using the correct measurements and baking the cake until set.
* **Cake stuck to the pan:** Ensure you run a knife or spatula around the edges of the pan before inverting. If it’s still stuck, try warming the bottom of the pan gently.
