Super Moist Chocolate Cake Squares With Fudge Frosting

Ingredients You Need

For the Chocolate Cake

  • 1 ½ cups all-purpose flour
  • 1 cup granulated sugar
  • ½ cup brown sugar (adds moisture)
  • ½ cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • 2 large eggs
  • ½ cup vegetable oil
  • 1 cup warm milk
  • ½ cup hot water or hot coffee
  • 1 teaspoon vanilla extract

For the Fudge Frosting

  • 1 ¼ cups chocolate chips OR chopped chocolate
  • 3 tablespoons butter
  • ½ cup heavy cream OR evaporated milk
  • 1 teaspoon vanilla
  • Optional: pinch of salt

🥣 Making the Cake Batter

This cake comes together quickly and cleanly — no mixer required unless you prefer.

Step 1 — Mix Dry Ingredients

In a large bowl, whisk together:

  • flour
  • cocoa powder
  • baking powder
  • baking soda
  • salt
  • both sugars

Combining everything evenly prevents lumps and ensures even baking.

Step 2 — Add Wet Ingredients

Add eggs, oil, vanilla, and warm milk to the dry mixture. Whisk gently until smooth.

Step 3 — Add Hot Water

Pour in the hot water (or hot coffee) while whisking.

The batter will become thin — this is the secret to a moist, soft crumb and deeper chocolate flavor.

🔥 Bake the Chocolate Cake

Prepare the Pan

Grease and lightly flour a square or rectangular baking dish, or line with parchment.

Bake

Pour batter evenly into the pan and bake at 175°C / 350°F for 25–30 minutes.

Check doneness by inserting a toothpick — moist crumbs are perfect, but no wet batter.

Cool the cake fully so the frosting settles beautifully.

🍫 Make the Fudge Frosting

The frosting is thick, glossy, and creamy — like a melted chocolate bar over cake.

Step 1 — Heat Cream

Warm cream in a saucepan or microwave until steaming (not boiling).

Step 2 — Add Chocolate & Butter

Pour the hot cream over chocolate chips and butter. Let sit 2–3 minutes, then whisk until smooth and silky.

Step 3 — Flavor

Add vanilla and a pinch of salt (optional but enhances flavor).

Let the frosting cool slightly until thick enough to spread easily.

🍰 Frost & Slice

Spread the chocolate frosting generously over the cooled cake.

Don’t hold back — the thicker the layer, the better!

Let sit for 10–15 minutes, then slice into squares like brownies.

😍 The Result

Just like your photo:

✔ Deep chocolate color

✔ Soft, fluffy crumb

✔ Melt-in-your-mouth thick frosting

🍽 Serving Ideas

Serve warm, room temperature, or chilled. Pair with:

  • Vanilla ice cream
  • Fresh berries
  • Whipped cream
  • A cold glass of milk
  • A cup of coffee or tea

They also pack perfectly in lunchboxes or dessert platters.

💡 Flavor Twists

Make this cake YOURS every time you bake it:

Rocky Road Topping

Sprinkle mini marshmallows + nuts before frosting sets.

Nutella Swirl

Spread Nutella under the frosting or swirl into batter.

Cookies & Cream

Fold crushed Oreos into batter or sprinkle on top.
