Step-by-Step Instructions

1. Preheat & Prep

Preheat oven to 350°F (175°C).

Grease an 8×8-inch baking pan with butter or nonstick spray—or line with parchment paper for easy lifting.

2. Mix Dry Ingredients

In a medium bowl:

Whisk together flour, sugar, cocoa powder (if using), baking powder, baking soda, and salt until no lumps remain.

✅ No sifter? Break up cocoa clumps with a fork. 

3. Blend Wet Ingredients

In a separate bowl or measuring cup:

Stir milk, oil (or melted butter), vanilla, and vinegar until smooth and slightly frothy.

4. Combine Batter

Pour wet ingredients into dry.

Stir gently with a spatula just until combined—do not overmix.

❗ Overmixing = tough cake. 

Optional: Fold in chocolate chips, nuts, or fruit.

5. Bake Fast & Golden

Pour batter into prepared pan and spread evenly.

Bake 12–15 minutes, until:

Top is springy to the touch

A toothpick inserted near the center comes out clean or with moist crumbs

✅ Don’t open the oven early! Heat loss can cause collapse. 

6. Cool & Serve

Let cool in pan 5–10 minutes—this helps set the crumb.

Slice while warm or at room temperature.

Top as desired:

Dust with powdered sugar

Drizzle with ganache

Serve with whipped cream or ice cream

Enjoy with a cold glass of milk, hot tea, or coffee.

You Must Know

Use room-temp milk —cold liquid slows rise.

Don’t skip the vinegar —it reacts with baking soda for lift and fluffiness.

Cocoa is optional —make it vanilla by omitting it (add ¼ cup more flour).

Tastes better the next day? Store covered—it stays moist for up to 3 days.

Freezer-friendly —wrap tightly and freeze up to 3 months.

Storage Tips

Store at room temperature in an airtight container for up to 3 days.

Refrigerate if topped with whipped cream or fruit (up to 2 days).

Freeze un-iced cake: Wrap well, thaw at room temp, then refresh with a warm-up (350°F for 8 mins).
