Should You Wrap Cakes in Plastic Wrap? The Truth Explained

If you’ve ever baked a cake and worried about it drying out, chances are you’ve asked yourself: “Should I wrap my cake in plastic wrap?” This question comes up constantly in baking groups and forums — and the advice online can be confusing. Some swear by wrapping their cakes straight from the oven, while others warn about mould and soggy textures.

So what’s the truth? Let’s break down the pros, cons, and best practices for wrapping cakes in plastic wrap — especially when it comes to mini loaf cakes, birthday cakes, and layer cakes.

Why Do Bakers Wrap Cakes in Plastic Wrap?

The main reason bakers wrap cakes is to lock in moisture. Freshly baked cakes start to lose moisture quickly, and plastic wrap creates a barrier to slow that process. Done correctly, it helps you:

• Keep cakes soft and tender

• Prevent refrigerator dryness

• Store cakes longer before decorating

But here’s the catch — wrapping the wrong way can actually ruin your cake.

The Biggest Mistake: Wrapping Cakes While Hot

One of the most common myths is that you should wrap your cakes the moment they come out of the oven.

The problem: Wrapping hot cakes traps steam. That moisture condenses inside the plastic, creating the perfect environment for mold growth and an unpleasant gummy texture.

The fix: Always let your cakes cool completely on a wire rack before wrapping. Room temperature wrapping = moisture retention without the risk.

When to Use Soaking Syrups Instead

If you’re relying on plastic wrap because your cakes come out too dry, the issue may be the recipe itself. Instead of wrapping immediately, consider using a soaking syrup (simple syrup):

• Best for: Butter cakes, genoise sponge, chiffon

• Not necessary for: Oil-based cakes (like chocolate fudge, carrot, or buttermilk loaves) — they already stay moist

How Long Can You Store Wrapped Cakes?

Here’s a safe guide for wrapping cakes in plastic wrap:

• Room temperature (wrapped & airtight): 2–3 days

• Refrigerator: 3–5 days (but only for cakes with fillings that require chilling)

• Freezer: Up to 3 months (double-wrap in plastic + foil to prevent freezer burn)

Always bring cakes back to room temperature before serving for the best texture and flavour.

Alternatives to Plastic Wrap

If you’re aiming for more sustainable or bakery-level storage, try these instead:

• Cake boxes or airtight containers — great for decorated cakes

• Beeswax wraps (for small loaves) — eco-friendly alternative

• Freezer-safe bags — especially for larger batches

Wrapping Isn’t a Substitute for a Good Recipe

At the end of the day, the best defense against dry cake is a well-balanced recipe and proper baking technique.

• Don’t overbake — test with a skewer or cake thermometer (done at ~98°C / 210°F in the centre).

• Choose the right formula — oil + buttermilk or sour cream cakes naturally stay moist longer.

• Use syrup wisely — to extend shelf life or balance drier sponge-style cakes.

So, should you wrap cakes in plastic wrap? Yes — but only if done correctly. Cool completely, wrap tightly, and store at the right temperature for your cake type. And remember, moisture starts with your recipe and bake time, not just the wrap.
