This classic marshmallow strawberry shortcake slice is a firm favorite in our family. The combination of the fluffy marshmallow with the shortcake biscuit base is hard to beat. Traditionally we made this slice without the strawberry jam center but the jam really does bring the entire slice together and makes it even more delicious! This is a slice that will impress which makes it perfect for bake sales, birthday parties, or visitors. I warn you though, this slice is super easy to make which makes it a great treat to have with your afternoon tea or coffee.

Don’t be put off by the steps involved in making this slice as it is actually super easy to make! The first time that I made this slice I have to admit that I was a little apprehensive of making marshmallow but after that initial time this is one of my favorite things to make. It really is quite therapeutic watching the gelatin, water, and sugar slowly transform into a marshmallow delight.

The Process

To start with the slice base is prepared. This is done by creaming together the butter and sugar and then adding the vanilla essence and eggs. To the creamed ingredients all of the dry ingredients are added and mixed well together. Finally, the shortcake mixture is pressed into a slice tin and baked.

Once the base has slightly cooled add the optional strawberry jam layer. You want to get a thin and even layer of jam. Set the base aside and make your marshmallow topping.

Making the marshmallow topping is a little like beating meringue. You really DO want to use either an electric hand beater or an electric stand mixer as it will save you a massive amount of time! In saying that my grandmother always managed to make an amazing pavlova using one of these manual egg beaters!

No matter what beater you use to make marshmallow it will take some time. If you are unsure if it is done then beat for longer, you want it to be stiff. Try rubbing a little marshmallow between your fingers to check that all of the sugar has dissolved. Add in the food coloring (if using) and vanilla essence towards the end of the beating process. When you are happy with the marshmallow gently pour it onto the cooled shortcake slice.

    These strawberry treats are perfect to make with the kids. Curious if I could make them into rainbow colors as well.

      Yes, our girls love them! I think you could but would be quite fiddly. It would be easier to do 2 different colors or perhaps try doubling the marshmallow topping recipe so you have more to work with to get even layers. Would love to see the results if you do attempt a rainbow slice!
