# Easy Chocolate Cake with Hot Water and Cocoa Sauce

> The secret to a moist chocolate cake is that **a cup of boiling water is added last**, leaving the batter **very runny — and that is required, do not add more flour**. The hot water blooms the cocoa flavor, keeps the cake tender, and keeps it moist until the third day, while extra flour is what makes it dry.

This easy chocolate cake is made in a single bowl using cups, with no long whipping or electric mixer, and with ingredients found in any Egyptian kitchen: cocoa, flour, oil, and milk. It is topped with a milk and cocoa sauce made on the stove in 5 minutes, making it ready for guests without any fuss.

## Ingredients

- 1.75 cup — flour
- 0.5 cup — unsweetened cocoa powder
- 1.5 cup — sugar
- 1.5 tsp — baking powder
- 1 tsp — baking soda
- 0.5 tsp — salt
- 2 — eggs at room temperature
- 1 cup — milk
- 0.5 cup — oil
- 1 tsp — vanilla
- 1 cup — boiling water (or hot plain coffee)
- 1 cup — cold milk for the sauce
- 3 tbsp — cocoa powder for the sauce
- 4 tbsp — sugar for the sauce
- 1 tbsp — starch for the sauce
- 1 tbsp — butter for the sauce

## Method

1. **Oven and Pan** — Preheat the oven to **180°C**, grease a **24 cm** pan with oil, dust it with **cocoa instead of flour**, and tap out the excess — flour leaves a white layer on the sides of dark cakes.
2. **Dry Ingredients** — In a large bowl, sift **the flour, cocoa, baking powder, and baking soda**, then add the sugar and salt and whisk together. Cocoa tends to clump, and sifting breaks up lumps that would otherwise remain as dry spots inside the cake.
3. **Wet Ingredients** — In another bowl, beat **the eggs, milk, oil, and vanilla** for a minute until well combined.
4. **Quick Mixing** — Pour the wet mixture into the dry mixture and stir with a whisk for **1 minute** until the batter is smooth and lump-free. You don't need a long whipping process here — the baking soda and baking powder are what will make the cake rise.
5. **Boiling Water** — Pour in **the cup of boiling water** gradually while stirring. The batter will become **as runny as a heavy soup** — this is correct, do not add more flour. The hot water dissolves the cocoa and brings out its flavor and aroma.
6. **Baking** — Pour into the pan and bake on **the middle rack for 40–45 minutes**, and **do not open the oven door for the first 30 minutes**. If using a 22x32 cm rectangular tray, the time drops to **30–35 minutes**.
7. **Skewer Test** — Insert a toothpick into the center: if it comes out with **moist crumbs**, it is done. Do not wait until it comes out completely dry, because the cake continues to cook from its residual heat as it cools.
8. **Cocoa Sauce** — In a saucepan while the heat is still off, dissolve **the cocoa, sugar, and starch in the cold milk** — starch clumps in hot milk. Turn on the heat to medium and whisk constantly for **4–5 minutes** until it thickens and coats the back of a spoon, then remove from heat and stir in the butter.
9. **Inverting and Glazing** — Let the cake sit for **10 minutes** in the pan, then invert it onto a serving plate and let it cool. Pour the sauce while it is **warm** over the top and let it drip down the sides — warm sauce poured over a warm cake gets absorbed inside rather than just sitting as a layer on top.

## Tips

- Use bitter dark cocoa — it provides a deep color and strong flavor. Sweetened cocoa blends yield a pale and overly sweet cake.
- Swap the boiling water for hot plain coffee: you won't taste the coffee, but the chocolate flavor will stand out much stronger.
- If the sauce clumps, whisk it vigorously while it's still on the heat, and if it gets too thick, add a couple of tablespoons of milk.
- This same batter works for cupcakes: fill the liners two-thirds full and bake for 18–20 minutes.

## FAQ

### Why does chocolate cake turn out dry?
Usually due to too much flour (scooping flour into a packed cup adds more than needed), or because it stayed in the oven until the skewer came out completely dry. Measure the flour by spooning it into the cup and leveling the top, and take the cake out as soon as the skewer comes out with moist crumbs.

### Can I make it without baking soda?
You can omit the baking soda and use 3 teaspoons of baking powder instead. The cake will still rise, but its color will be slightly lighter because baking soda reacts with the acidity of cocoa to darken its color.

### Can I use butter instead of oil?
You can use half a cup of melted butter, but oil keeps the cake softer and more moist even in the fridge. Butter solidifies when chilled, making the cake firm after it cools.

### How long does the cake last and can it be frozen?
With the milk sauce, it can be stored covered in the fridge for 3–4 days. Without the sauce, it can be wrapped tightly in plastic and frozen for up to a month, then thawed in the fridge overnight and covered with sauce afterward.
