STEP 1: divide The Cake Mix In Half

The ingredients in your boxed cake mix have been sitting and settling for a little bit on that grocery keep shelf. Before you gain started, seize the bag and also give that a quick shake to mix everything up.

Now, girlfriend could try to dump fifty percent the bag out but dividing the mix right into equal parts will yield the best results. Here are two methods to go about it.

Option 1: making use of a Scale

A conventional boxed cake mix (in the US) weighs 15.25 ounces. So half a box of cake mix weighs 7.625 ounces.

To measure the end half, place a medium bowl on your scale and zero the out. To water the mix into the bowl till it measures 7.62 ounces.

Option 2: making use of Measuring Cups

A cake mix that weighs 15.25 ounces has 3⅓ cups of mix total. So fifty percent a box of conventional cake mix is 1⅔ cups.

To measure the end half, usage the spoon-and-sweep method. This technique will save you native compacting the mix and also taking an ext than half.

Place a piece of parchment file on your counter.Spoon the mix into a dry measuring cup and also use the back of a knife to level off the mix.Repeat till you have 1⅔ cups of mix measured out.If girlfriend have any type of of the dry mix ~ above the parchment paper, to water it ago into the bag through the other half of the cake mix.

Did that sound confusing? If the did, inspect out this post by sugar Spun operation on exactly how To effectively Measure Flour.

Okay, now that you’ve acquired your mix split let’s look in ~ the various other ingredients.

STEP 2: division The Water and Oil In Half

Take the quantity of water called for and also divided it in half. So, if the box instructions call for 1 cup of water usage 1/2 cup.

When it comes to the oil, some boxed cake mixes (like Betty Crocker and also Pillsbury) speak to for 1/2 cup that oil while others (like Duncan Hines) use 1/3 cup.

Take whatever the indict on her box contact for and divide it in half.

Half that 1/2 cup = 1/4 cup or 4 tablespoonsHalf of 1/3 cup = 2 tablespoons + 2 teaspoons

I generally make our cake mix v olive oil or avocado oil yet you can use any vegetable oil friend want.

If you usage coconut oil (in a liquid state), simply make certain the various other ingredients room at room temperature (and not cold). Otherwise, the coconut oil will certainly harden into lumps and also muck up your batter – it will certainly be sad.

STEP 3: Halve The eggs + Substitutions

If the box calls for 2 eggs, just use one egg.

But what if that calls because that 3 eggs?

The quick Answer: use one totality egg + fifty percent a to win egg.

To measure out the beaten egg, cracked an egg right into a small bowl and also beat with a fork till the white and also yolk are combined. Measure out half, around 1½ come 2 tablespoons (give or take it a little). For more tips check out this just how to Measure half an Egg post.

*You’ll desire to refrigerate the continuing to be beaten egg and also use it within 24 hours.

The cake we made utilizing this method turned out great. It to be moist with a pretty flavor and light texture. Just what you’d intend from a cake mix.

BUT…that leftover beaten egg to be a small inconvenient and also potentially wasteful. Therefore we wanted to see if it might be avoided.

We grabbed more lemon cake mix, split the crate up and tried out some substitutions.

Applesauce

First, us replaced every one of the eggs through 1/4 cup that unsweetened applesauce. (Spoiler: don’t execute this – it’s not a great option).

The Results: The cake barely rose, was doing not have in flavor and when i tried to cut it ~ cooling, the cracked and also fell apart.

Would We perform It Again? Nope.

Greek Yogurt

Another option is come replace every one of the eggs through 2 tablespoons of level yogurt, constant or Greek variety.

The Results: The cake didn’t rise much however it did organize together well and also tasted great. The crumb was denser but not in a poor way.

Would We use This Substitution Again? Yep. Ns think the pound cake-style texture would certainly be perfect because that pairing with whipped cream and also berries, particularly for a summer brunch or Mother’s work treat.

Egg + Greek Yogurt

The last alternative we make the efforts was utilizing one egg to add a tablespoon that yogurt.

The Results: This cake was tender, had a pretty flavor and was lighter than the all-yogurt option. While it did crumble some, the didn’t autumn apart like the applesauce one.

Would We usage This Substitution Again? 100% Yes! overall it had a good flavor and nice texture. Plus it to be so straightforward to take a spoonful of yogurt and add it in with the 1 egg.

New! What around using 1 egg + part of one more egg?

A most small-batch baking recipes call for a solitary egg white or a solitary egg yolk (like our rich and fudgy toaster oven chocolate cookies). Leaving you with some part of an egg to usage up.

To view if an extra egg yolk or one egg white would make a great addition to fifty percent a cake mix we ordered a box of the exact same lemon cake mix indigenous before and also got baking.

*

About a main after this marathon baking session we determined to try two an ext options. Making fifty percent a mix using only 1 egg and using 2 eggs.

The 1-Egg Results: The cake was noticeably drier 보다 the various other cakes. While the still had some structure it crumbled easily. As soon as you took a bite, the cake would kind of loss apart in her mouth.

Would We usage This Substitution Again? more than likely not. This cake was definitely much better than the applesauce option, but it no something i enjoyed. Tim did say he would eat it again.

The 2-Eggs Results: This cake climbed taller than any type of of the various other cakes, to be super bouncy, and practically sponge-like. Ns felt like I can easily carve and frost it there is no a lot of crumbs.

Would We use This Substitution Again? Maybe. Tim really delighted in this cake. I believed it to be light with a nice flavor but that it might use much more moisture. Ns might shot it again, swapping the water because that milk and including a little yogurt.

If you’re not sure which egg-option is for you, it’s always a good bet come stick v 1 whole egg + half an egg.

Here room a few ideas to usage up the leftover egg:

Grab a frying pan, scramble the egg and include it to a sandwich or salad.

STEP 4: choose Your Pan

An 8 x 8 x 2-inch pan or an 8 or 9-inch round pan are an excellent options for making half a cake mix.

If you don’t have one that those pans we’ve got a bunch of principles for you!

8 1/2 x 4 1/2 bread Pan2 round 6 x 2-inch Cake Pans2 6-cup Muffin Pans or a 12-cup Muffin Pan11 x 7-inch Cake PanQuarter paper Pan8.5 x 6.5-inch Casserole Pan

*Pro Tip: use a plastic knife to cut the cake, the won’t scrape your metal pan.

Once you’ve obtained your pan sorted, make sure to grease the so her cake no stick.

STEP 5: Preheat The Oven

If you baking v a typical ‘big’ oven, follow package directions for the correct temperature setting.

For a standard toaster oven, I uncover reducing the temperature by 25 degrees yields the ideal results.

When using the convection alternative on ours countertop oven, ns reduce the temperature by 50 degrees (making certain not to go listed below 300F). This helps to offer the middle sufficient time to chef through there is no over-baking the edges.

*As all ovens space different, you might need come play roughly a little to find the perfect temperature setting for your certain oven.

STEP 6: Mix and Bake

Now that you’ve gained your mix and ingredients divided, your pan selected and prepped, and also your cooktop preheating all that’s left to do is mix increase the batter and also bake it.

Follow the directions on your package because that combining half of the mix and half of the ingredients. Then pour the batter right into your ready pan and also bake according to the directions.

Check On your Cake Early

The type of mix, pan, ingredients, and also oven used will influence the baking time.

Cupcakes could take the exact same amount that time (ours take it 15 minutes)Because the thinner, a quarter sheet pan will bake up rapid (about 14 come 16 minutes)A loaf pan will most likely take longer (about 22 come 25 minutes)Two ring 6 x 2-inch cake pans will have actually a much shorter baking time (about 15 come 18 minutes)

For the ideal results, begin checking because that doneness 8 to 10 minutes previously than the shortest baking time listed because that a cake pan on her box. Climate add an ext time together needed.

You’ll recognize the cake is ready once a toothpick put into the center comes out clean.

Wait because that the cake to cool fully before digging in!

Storing The Leftover dried Mix

I recommend placing the continuing to be mix in a reusable sandwich bag. That method you can toss it right into the cake mix box v the directions and ingredients info.
