How to make easy Baby Blocks for your cakes

If you’re creating a cake for a baby shower, a new baby, a christening or a first birthday, a great way to add text onto your cake is by creating baby blocks. You can then add names, words, numbers or even dates. Baby Blocks or blocks in general have always been a little tricky when making these with fondant. It’s hard to get your blocks to have nice straight sides and sharp edges. In this weeks video tutorial I’ll be creating some baby blocks in different styles using the silicone ‘Build a Block’ mould by Sweet Stamp. Blocks have never been so easy to create…

Just click below to watch how I made the blocks in this weeks video tutorial ⇩

The Mould

The blocks themselves measure 4cm or 1.5 inches making them the perfect size for cake toppers or to use around the edge of your board.

How to make baby blocks for your cakes

This mould makes it so easy to create little blocks, whether your creating baby blocks or maybe blocks to go onto a MineCraft or Mario cake. Whatever kind of blocks you need just push in your modelling paste, freeze and you have perfect blocks.

I’ve tested this mould quite a few times now and have found that a really firm fondant or modelling paste works best. I combined 50 / 50 fondant to gumpaste (Squires floral Paste) or you could add in a little tylos powder. You want your blocks to firm up quite quickly so they don’t sink down as they dry. To get the modelling paste out of your mould you will need to place your mould in the freezer for around 20 – 30 minutes. This helps firm up the blocks and with a little push on the back they come right out. As its a silicone mould you can even use chocolate or candy melts to create perfect little blocks.

TOP TIP – Now my biggest tip would be when placing your mould into the freezer pop it into a sandwich bag or an airtight box first. The blocks still freeze but it stops any moisture from the freezer going into your modelling paste. I have found if you just place your mould into the freezer when you take it out, because of the change in temperature the blocks do get a little condensation on the outside and this makes them a little sticky, so you have to leave them to one side for this to dry. It also slows down the modelling paste setting, but by adding them into an airtight bag or box, this stops this completely and they are fine to use straight out of the mould.

As well as the ‘Build a Block’ mould I also used the Classic Letter set and the frosting letter set for the ‘A’ & ‘C’ on the blocks.

Now if you’ve followed me for a while you will know how much I love the Sweet Stamp letter sets. They make it so easy to add lettering onto your cakes, but as well as using the Sweet Stamp letter sets I also used the FMM Tappits for an alternative design. These letter cutters have been around for so many years and I think were maybe the first set of letter cutters I ever got. Like the Sweet Stamp Classic letter set they have a very traditional style making them perfect for the baby blocks. Using the Tappits I was able to cut out this small ‘B’ to add onto my blocks surounded by a little boarder.

When using Tappits one tip would be to use a firm modelling paste or gumpaste as they can be a little fiddly to get out. Also dust your gumpaste with a little cornflour as this helps them release as you tap them.

If you’re looking to make your own blocks to add onto your cakes this mould makes it so quick and easy. You no longer have to use your smoothers to try and get your fondant into a block. I really hope you will find this tutorial useful and be able to use it to add a personal touch on to your cakes.
