Simple Syrup Recipe

filed under: Decorating on April 24, 2015

Simple syrup is a baker’s secret weapon. I use it on cakes, cupcakes, cookies (on the rare occasion) and even in my cocktails! The recipe for simple syrup is easy and can be modified in a million ways. I also have a Chocolate Simple Syrup that works best on chocolate cake and red velvet cake!

The GREATEST trick for cake makers!

How to Make Simple Syrup

The equation stays the same no matter how much you make. I have made a large batch and used 3 cups sugar and 3 cups water. It is a basic 1:1 ratio.

I like to store my simple syrup in a plastic bottle that has easy pouring and can close. If you do not have a bottle you can spoon it over the cake or even brush it over the cake with a pastry brush.

I use about 1-4 tablespoons per layer, depending on the size of the layer.

How to make sure your cake is moist and delicious EVERY single time!

This was a 12-inch layer of cake so I used almost 1/4 cup! (or 4 tablespoons)

How to make sure your cake is moist and delicious EVERY single time!

After I pour the simple syrup over the cake I will wrap it in plastic wrap then store in the refrigerator for up to 2 weeks.

If I am freezing cake I will soak layer with simple syrup, wrap in plastic wrap, then place the cake in a sealable plastic bag or air-tight container. (I have seen it written that you can store up to 3 months.)

Now for the “why” of simple syrup:

Simply put it keeps the cake moist throughout every stage of assembly and decoration. Not only does it help keep your cake moist, but it also helps to add sweet flavor which is always good!

Questions about Simple Syrup

Will it make my cake too sweet?

No. It will enhance the sweetness in your cake but not alter the flavor.

Can I use simple syrup with fillings and frostings?

Yes, definitely. You should use simple syrup on your cake layers and then fill/decorate as you normally would.

Can I make it different flavors?

Absolutely! Simple syrups can be quite diverse. Mix in spices, extracts, fruit—and you have instant flavored sweetener!

    I’m 66, my Mother used this a lot. Fast, easy to make & delish! She used it on homemade 2 layer cake. Banana slices over each layer, then pour syrup over each & repeated over top layer!

  • judy says:

    Is simple syrup used if you are storing the cake layers to use at a later time or is this used while putting the cake together to serve the same day?

  • D griffiths says:

    I’m 87and do not do the baking I did 2years ago but I continually read your recipes. 3 years ago I lost all my recipies of 60 years but now I read your new ones

    • Cherry says:

    I usually make my cakes in an 9×13 pan. Will this method work of that size cake?

    • Janet Lennon says:

      If it’s cake, yes. Size of pan simply has no bearing on the matter.

  • Adriana says:

    Can’t get any easier! Thank you!

    I wanted to mix coffee and alcohol to a chocolate cake (it’s the italian in me) Should I use this as part of the liquid ratio, or do you suggest I add water to the mix?

  • Diva says:

    Lucan you give me examples and measurement of making simple syrup in different flavors?

  • C says:

    I am 31 and I have been baking since I was big enough to stand on a kitchen chair in my gandmom’s kitchen. I see this used a lot but I have never found this necessary. I can only see myself using this if I have a cake that was terrible over baked and therefor very dry. Even for big projects my cakes do not dry out.

  • Kendall says:

    I have cake layers that I have already stored in the freezer and am only now just thinking maybe a want to attempt a simple syrup for the first time. Can I put in simple syrup after I have thawed the layers tomorrow? or does it need to be added before freezing? Thanks!

    • Amanda says:

      You can add after the cake has thawed. 🙂

  • Anneke says:

    I have been thinking about using,it but we can’t have sugar. Do you know if it would work with splenda?

    • Blake says:

      I have tried this and it works just fine

  • Susan Stern says:

    Starting using this method when I had a recipe for
    Baba au Rum. After cake is baked it called for 1/4 cup rum added to 1/3 cup sugar dissolved in saucepan and poured over cake. I have used this in many cakes substituting the liquor for water or different types of liquor.

  • Antionette says:

    Do I pour it on cupcakes while their completely cool or still warm ?

  • ED HAYWOOD says:

    Has anybody used “Sugar in the Raw” for the syrup? I love the slight “molasses” taste it has.

  • Olusola Ajayi says:

  • Angie says:

  • Gerda says:

    I want to use your simple syrup to moisten a cake…….. does on cool the cake before syrup or does syrup go on still warm cake?
    Thanks a mill,
