Baking 4 Inch Cake Layers: Sizes, Batter and Times

Updated September 2026 · Baking Resources

A 4 inch round pan, 2 inches deep, holds about 1 3/4 cups of water to the rim, which means 1 to 1 1/4 cups of batter once you leave the correct third of headroom. Two of those layers stacked and frosted feed 2 to 4 people. Baking 4 inch cake layers takes 22 to 30 minutes at 350°F, only slightly less than a full size layer, because bake time follows batter depth rather than pan width.

A 5 inch pan is the next step up: 2 3/4 cups to the rim, 1 3/4 cups of batter, 4 to 6 servings. The jump from four to five inches sounds small and adds 56 percent more floor area.

Mini cake pan sizes: the full capacity chart

Every figure here is measured across the inside of the top rim, which is the only measurement that matters. Batter volume assumes a two-thirds fill, the standard for anything with baking powder or soda in it.

Two honest caveats. Brands vary by a quarter cup at the same nominal size, mostly because of how much the sides slope, and a sloped-side pan measured at the base can be half an inch smaller than the number on the label. Straight-sided pans hold more than the chart says and sloped ones hold less.

The fix takes thirty seconds. Fill your own pan from a measuring cup, count the cups, and write the number on masking tape stuck underneath. You never guess again.

Why four inches is so much smaller than six

Floor area scales with the square of the diameter, so cutting the diameter does far more damage than your eye expects.

The cleanest number on that chart: a 4 inch pan is exactly one quarter of an 8 inch pan. Halve the diameter, quarter the floor. That single relationship replaces most of the arithmetic in mini cake baking, because it means one 8 inch layer's worth of batter fills four 4 inch pans.

A 5 inch pan sits at 39 percent of an 8 inch, so a five inch cake takes a little over a third of a standard recipe layer. Our round cake pan sizes chart has the full-size numbers if you need to compare beyond six inches.

Baking 4 inch cake layers: temperature and time

Depth decides the clock, not diameter. A 4 inch layer filled to 1 1/4 inches and a 9 inch layer filled to 1 1/4 inches finish within a few minutes of each other.

Small pans do run a touch faster than the chart suggests for one reason: a 4 inch pan has 12.6 square inches of floor and 25 inches of hot wall, so heat comes in from the sides more aggressively than it does in a big pan. Start checking at 20 minutes the first time and write the real number down.

Doneness beats arithmetic. A butter cake is done at 205 to 210°F in the center whatever pan it is in. A skewer with a few moist crumbs says the same thing less precisely.

Two problems specific to small pans. They dome hard, because the edges set while the center is still rising in a small area. Drop the oven to 325°F and add 5 to 8 minutes, or wrap a damp strip of old towel around the outside. And they overbrown at the rim, so pale aluminum beats dark nonstick here by a wide margin. If your pan is dark, drop 25°F.

Scaling a full size recipe down to individual size cake pans

Multiply every ingredient by the factor in the table. These are area ratios, which is the correct way to scale a cake.

The bottom two rows are the useful ones. A two-layer 8 inch recipe makes eight 4 inch layers, or four tall two-layer mini cakes, with no arithmetic at all. A standard box mix yields about 4 1/2 cups of batter, which fills four 4 inch pans at just over a cup each.

That is the fastest route into mini cakes: bake the full recipe, fill four small pans instead of two big ones, and split any leftover into cupcakes at 1/3 cup a well.

Worked example: an 8 inch recipe converted to two 4 inch tiers

What you have: a recipe written for two 8 inch rounds, and two 4 inch pans. You want one small two-layer cake, not eight layers.

Step 1. The factor. Two 4 inch pans total 25.2 square inches. Two 8 inch pans total 100.5. That gives 0.25, so scale everything to a quarter.

Step 2. The arithmetic. Say the recipe calls for 280 g all-purpose flour, 300 g granulated sugar, 4 large eggs, 227 g butter and 240 ml milk.

• Flour: 280 x 0.25 = 70 g, which is a hair over 1/2 cup at 125 g per cup
• Sugar: 300 x 0.25 = 75 g
• Butter: 227 x 0.25 = 57 g, which is 4 tablespoons
• Milk: 240 x 0.25 = 60 ml, or 1/4 cup
• Eggs: four large eggs weigh about 200 g shelled, so 200 x 0.25 = 50 g of beaten egg, which is one large egg

Step 3. The lucky break. A quarter of four eggs is exactly one egg. That does not always happen, and when it does not, beat the eggs and weigh out what you need rather than cracking a fraction by eye.

Step 4. The check. Those weights come to roughly 310 g of batter, which is about 2 1/3 cups. Split between two pans, that is 1.17 cups each, and the two-thirds line for a 4 inch pan is 1.15 cups. You are right on target.

Step 5. The bake. Same depth as the original, so the same 350°F and roughly the same time. Check at 20 minutes and pull at 205°F.

Our guide to scaling a recipe covers the ingredients that do not scale in a straight line, including leavening and salt, which both need a second look below a half batch.

Servings and frosting for a small cake

Servings depend entirely on how you cut, and small cakes get cut generously because they look modest.

Add 1/4 cup for a piped border and another 1/2 cup if you are covering the whole thing in rosettes. Our frosting calculator gives batch weights by style and coverage, and the cake servings calculator draws the cut pattern so you can see where the slices come from.

For parchment, cut a circle to the exact inside diameter. A collar strip for clean vertical sides needs the circumference, which is pi times the diameter: 12.6 inches for a 4 inch pan and 15.7 inches for a 5 inch pan. Round up an inch for the overlap. How to line a cake pan has the folding trick that gets you a clean circle without tracing.

The individual small cake tins worth owning

"Cake mold small size" covers a pile of very different objects, and they do not all bake the same way.

Solid aluminum, 4 inch, 2 inches deep. The workhorse. Buy four. Light metal reflects, so you get pale, even sides and a nearly flat top, and straight sides give you a clean stacking edge.

A cake tin 4 inch across and 3 inches deep. Bake one tall layer and torte it into two or three thin ones with a serrated knife. This is how you get a four-layer mini cake without owning four pans. Drop the oven to 325°F for the deeper bake.

4 inch springform. For anything you cannot flip out: cheesecake, mousse cakes, ice cream cakes. The seam leaks, so line the base with parchment and wrap the outside in foil for a water bath. A 4 inch springform nests inside a 6 inch cake pan, which nests in a roasting pan, and that stack is far easier to lift than a foil wrap.

Cake rings. Bottomless metal rings you set on a parchment-lined sheet pan. They give the sharpest edges of anything on this list and they store flat. Thin batters seep, so use them for thicker batters or seal the base with foil.

Ramekins. A 6 oz ramekin holds 3/4 cup, so it takes 1/2 cup of batter. Ceramic insulates, so add 5 to 10 minutes and expect no browning on the sides.

Silicone. Insulates rather than conducts. Add 10 to 15 minutes, expect pale sides, and always set it on a sheet pan so you can move it. Good for freezing and unmolding delicate things, weak where you want a crisp edge.

Mini loaf pans, 5.75 by 3 inches. Not round, but they hold about the same as a 5 inch round and they bake beautifully. Good when you want four small cakes from one recipe with no stacking involved.

DIY small cake pan: three that actually work

No mini pans in the house? All three of these have been used in real kitchens for decades.

The foil ring. Tear a length of heavy duty foil, fold it into a strip four layers thick and 2 1/2 inches tall, then form it into a circle 4 inches across. The strip needs to be about 13 1/2 inches long: 12.6 inches of circumference plus an inch of overlap. Clip the overlap with a binder clip, set the ring on a parchment-lined sheet pan, and grease the inside. It holds any batter thick enough to mound on a spoon.

The divided 6 inch pan. Fold a foil strip into a stiff wall and stand it across a 6 inch pan to make two half-moons, or across an 8x8 square to make two 4 by 8 rectangles. Press it hard against the floor and line each side with parchment. It leaks a little at the seam, which is fine for a thick batter.

The ramekin or oven-safe mug. Nothing to build. A 6 oz ramekin takes 1/2 cup of batter, bakes in 20 to 26 minutes at 350°F, and unmolds cleanly if you butter and flour it.

One safety note on the trick you will see online. Food cans make a tempting cake mold 4 inch across, but many cans carry a plastic-based liner that is not made for a dry oven, and cut can edges are genuinely sharp. A foil ring costs nothing and skips both problems.

Mini cakes versus cupcakes: which to bake

The two overlap more than people think, and the batter is often identical.

A 4 inch layer takes 1 1/8 cups of batter. A cupcake well takes 1/3 cup. So one 4 inch layer equals about three and a half cupcakes of batter, and a two-layer 4 inch cake uses roughly seven cupcakes' worth.

Cupcakes bake in 18 to 22 minutes, mini layers in 22 to 30. Cupcakes need no leveling, no torting, no crumb coat and no chilling before stacking. Mini layers give you a cake that looks like a cake, which is the entire reason to make one.

If you are baking for two people and you want it simple, cupcakes win. If it is a birthday and the photo matters, the 4 inch cake is worth the extra half hour. Either way, tall small cakes topple while warm, so cool the layers completely, chill 20 minutes before stacking, and run a bamboo skewer down the middle of anything over three layers. For the next size up, our 6 inch cake pan guide has the same numbers at that scale, and the brownie dish size chart covers the square pans.

Frequently asked questions

How much batter does a 4 inch cake pan hold?

About 1 3/4 cups of water to the rim in a standard 2 inch deep pan, which means 1 to 1 1/4 cups of batter at the correct two-thirds fill. A deep 4 by 3 inch pan holds around 2 1/2 cups to the rim and takes 1 3/4 cups of batter. Cheesecake barely rises, so those pans can go to three quarters full.

How long do you bake a 4 inch cake?

Twenty two to thirty minutes at 350°F for a standard layer filled to about 1 1/4 inches. Thin torte layers at 2/3 cup take 15 to 20 minutes. A deep 4 by 3 pan filled to 2 inches needs 40 to 55 minutes at 325°F. Pull any butter cake at 205°F in the center rather than trusting the clock.

How many people does a 4 inch cake serve?

Two to four for a frosted two-layer cake, and four to six for a three-layer one. A five inch cake stretches that to four to six and six to eight. These are generous dessert slices, since a small cake gets cut like a personal cake rather than a party cake.

Can I use a 4 inch pan instead of a 6 inch?

Only with less batter. A 4 inch pan has 56 percent less floor, so the same batter sits more than twice as deep and the edges overbake before the center sets. Scale the recipe to 0.44 of the 6 inch amount, or split it across two 4 inch pans and bake shorter layers.

What size is a 5 inch cake in cm?

Twelve and a half centimeters, and a 4 inch pan is 10 cm. European and Asian recipes usually list them as 10 cm and 12.5 cm tins, with the standard 2 inch depth written as 5 cm. A deep 4 by 3 inch pan is 10 by 7.5 cm.

How do I make a DIY small cake pan?

Fold heavy duty foil into a strip four layers thick and 2 1/2 inches tall, form it into a 4 inch circle about 13 1/2 inches long including the overlap, clip it closed, and stand it on a parchment-lined sheet pan. Grease the inside. It handles any batter thick enough to hold its shape on a spoon.

Do mini cakes need a lower oven temperature?

Not if the batter depth matches the original recipe, though 325°F gives you flatter tops and less doming in a small pan. Dark or nonstick mini pans do need the drop, since the high wall-to-floor ratio browns the edges fast. Pale aluminum at 350°F is the reliable default.

How many 4 inch layers does a box mix make?

Four. A standard box yields about 4 1/2 cups of batter, and each 4 inch pan takes just over a cup, so you get four layers with a spoonful left for a test cupcake. That is enough for two two-layer mini cakes, or one very tall four-layer one.
