Ingredients

Dry Ingredients

  • 2 cups (250g) all-purpose flour
  • ¾ cup (150g) sugar
  • 2 teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt

Wet Ingredients

  • 2 eggs (room temperature)
  • ½ cup (120ml) milk
  • ½ cup (120ml) oil or melted butter
  • ½ cup (120g) plain yogurt or sour cream
  • 1 teaspoon vanilla extract

Chocolate Batter

  • 3 tablespoons cocoa powder
  • 3 tablespoons milk
  • ¼ cup chocolate chips (optional but amazing)

Topping (optional but recommended)

  • Chocolate chunks or drizzle
  • Extra sugar sprinkle

Step 1 – Preheat & Prep

Preheat oven to 180°C (350°F).

Line a muffin tin with paper liners or grease lightly.

This recipe makes about 10–12 muffins.

Step 2 – Mix Dry Ingredients

In a bowl, whisk:

  • Flour
  • Sugar
  • Baking powder
  • Baking soda
  • Salt

Simple but important — this spreads everything evenly.

Set aside.

Step 3 – Mix Wet Ingredients

In another bowl, whisk:

  • Eggs
  • Milk
  • Oil or melted butter
  • Yogurt
  • Vanilla

Mix until smooth and creamy.

The yogurt is the secret here. It makes muffins insanely soft and moist.

Like… bakery level soft.

Step 4 – Combine Wet + Dry

Pour wet ingredients into dry ingredients.

Gently mix.

STOP when just combined.

Do not overmix.

Lumpy batter = soft muffins

Smooth overmixed batter = dense muffins

Trust the lumps.

Step 5 – Make the Chocolate Batter

Divide batter into two bowls.

Leave one bowl plain (vanilla).

To the second bowl, add:

  • Cocoa powder
  • Milk
  • Chocolate chips

Mix gently.

Now you’ve got chocolate heaven.

Step 6 – Create the Marble Effect

Here’s the fun part.

In each muffin cup:

Add 1 spoon vanilla batter

Then 1 spoon chocolate

Then vanilla again

Repeat until cups are ¾ full.

Now use a toothpick or knife.

Swirl gently.

Don’t over swirl or colors mix too much.

We want pretty marble waves, not mud.

Step 7 – Add Toppings

Sprinkle chocolate chunks or drizzle melted chocolate on top.

This gives that bakery-style look and gooey top.

Totally optional… but also totally worth it.

Step 8 – Bake

Bake for:

18–22 minutes

Until:

  • Tops are golden
  • Toothpick comes out clean
  • Kitchen smells irresistible

Let cool 5–10 minutes before removing.

But honestly… warm muffins are life.

Texture & Flavor

Let me describe that first bite.

Top → slightly crisp

Inside → fluffy, buttery, soft

Chocolate → rich and fudgy

Vanilla → sweet and light

Together?

Absolute perfection.

Like mini cakes disguised as breakfast.

Pro Tips for Perfect Muffins

Don’t Overmix

Biggest mistake. Mix gently only.

Use Room Temp Eggs

Helps smoother batter.

Fill Cups ¾ Full

Too full = overflow

Too low = flat muffins

Add Chocolate Inside Too

A few chips hidden inside = surprise melty goodness

Let Rest 5 Minutes

They finish cooking inside after baking

Fun Variations

Nutella Marble

Replace cocoa with Nutella

Double Chocolate

Add chocolate chips to both batters

Banana Marble

Add mashed banana to vanilla batter

Orange Chocolate

Add orange zest to chocolate batter

Coffee Chocolate

Add espresso powder for deeper chocolate flavor

Storage

Room temp: 3 days airtight

Fridge: 5 days

Freezer: 2 months

Reheat 10 seconds microwave = fresh again

Perfect for meal prep snacks.
