How to make a Warhammer Purity Seal Cake

I’ve been a mum for 12 years now, and for about ten of those years, I’ve asked my son what kind of cake he would like for his birthday. I’m no Mary Berry, but I can knock up a good sponge cake, and I’m happy to give pretty much anything a go. Over the years we’ve had a volcano cake, a train cake, a Minecraft block and a Pokémon cake, amongst others. This year he asked me to make him a Warhammer purity seal cake, so I gave it my best shot.

Whilst not wanting to diminish my son’s latest obsession, Warhammer is basically painting tiny figures and then having a ruckus with your mate who also has some painted tiny figures. It’s a world I don’t fully understand, but I don’t need to understand it, I just need to continue to fund it.

In essence the cake is three layers of Oreo sponge, with Oreo frosting between the layers and all over it, which make it look like a muddy battlefield. After tapping into the expertise of a Warhammer loving adult, we brainstormed some ideas. My friend did the hard work, the painting and his painted creations would also double up as birthday gifts for the birthday boy. My role was to make the cake, and the paper scroll for the purity seal.

This was a two part job, with my friend ordering a 3D printed purity seal coaster off Etsy and painting it up accordingly, and me creating the scroll. I did this using an app called Canva, which is free and I use it quite a lot for various design things. I added his name and some appropriate Warhammer words and logos, then printed it on cream paper. The font I used was IM Fell English SC, which was as close as I could get to authentic. Aging the scroll meant dabbing the paper with a damp teabag, which worked well.

Once dry, I lit a candle and carefully (VERY CAREFULLY) held the paper above the flame to give extra colour and raggedy edges to the scroll. Be careful not to actually burn the paper. I made sure I was doing this on a flame proof chopping board, so if it did go up in flames, I could put them out quickly. Together with the appropriately painted seal, it looked pretty darn good.

To make the Oreo cake

For his birthday, I made two of these cakes as he was having a family party and a party with friends. Click here to go to the recipe for the Oreos cake. You can make the sponge layers in advance. As long as they are well wrapped up, they will be fine for a day or two. The vanilla frosting is meant to look like a muddy, gritty battlefield, the kind a troop of Space Marines might find themselves on. The trick is to not overmix it, or it just becomes a dirge colour and not speckled. Don’t forget to save an Oreo or two to crumble up as extra dirt on top of the cake.

Follow the instructions on how to put the cake together, once you’ve got your Oreos cake built, it’s time to decorate it!

To decorate your Warhammer Purity Seal Cake

You will need a couple of toothpicks to hold some of the decorations in place, so don’t forget they’re there when it comes to serving your cake! Decide where you’re going to place your purity seal and using half a toothpick, pin the paper scroll in place. Using some of the Oreo frosting as glue, stick the purity seal down, on top of the cake, at the top of the scroll.

We also had a painted Space Marine to top off the cake. His base had been sculpted at the bottom so you could stick a toothpick in and anchor him into place, which was a stroke of genius. Around his feet I sprinkled some crushed up Oreos, which made him look like he was wading through mud.

As it was a birthday cake, I ordered some black candles, which finished it off nicely. My son absolutely loved his birthday cake and was impressed by how good it looked. If you’re into Warhammer and Oreos, then this is a relatively simple cake to put together, if you’ve got someone doing the painting for you that is!

It’s a brutal looking cake, but it really was delicious!

Visiting Warhammer World, Nottingham

This summer has been a busy one for my boy. He’s 11, about to start high school and busy learning to be more independent. He has many hobbies and interests, but one he shares with his cousin and best friend is Warhammer. For the uninitiated, Warhammer is mostly painting tiny figures and then playing war games with them. So this summer, I decided to take them both to Warhammer World in Nottingham, and what a day out that was!

Visiting Warhammer World, Nottingham

My own enthusiasm for Warhammer mostly extends to being supportive of my son’s interest in it. I was reassured that even someone with no prior experience of Warhammer would probably still enjoy their time there. I’m happy to say that I did, and I would go again. The boys however, aged 11 and 12 are pretty obsessed, and their excitement alone was pretty infectious.

We decided to make a couple of days out of our trip to Nottingham. It’s not that far from Manchester, so why rush? We stayed in town the night before, and after breakfast we grabbed a taxi to take us to Warhammer World. In terms of getting there, it’s really accessible by tram, bus or car, and there’s plenty of free parking.

It’s free to enter Warhammer World, but you do have to pay to explore the exhibition centre (currently £7.50 per adult, £5 per child over 12 years). It’s definitely worth visiting the exhibitions at least once, they really are incredible. The exhibition centre is made up of four rooms filled with painted figures, elaborate dioramas and lots of inspiration for two keen boys.

The exhibition areas are packed with thousands of Citadel and Forge World miniatures painted by the talented people at Warhammer World. They really are awesome, and we dashed from display case to display case being wowed by what we saw. The exhibition was really inspiring for the boys, they’ve seen Warhammer scenes in the shops, admired them and they were keen to emulate them, but this was on such a huge scale, it was a lot to take in. I recommend you really take your time through these areas. There’s an awful lot to look at. You are allowed to take photos for our own personal use, so the boys did take a few snaps of things they’d like to recreate at home.

Undoubtedly the highlight was The Battle For Angelus Prime, which is the largest display in the building. It’s housed in its own room, with a staircase winding around it, so you can appreciate it in 360°. It really has to be seen to be properly appreciated. It contains over 5,500 miniatures, and is over 22 feet in length, 12 feet wide and almost 20 foot high. It is big!

There are over 20,000 miniatures on display in the exhibition centre. All of them are fixed to their displays except one, an assassin which is moved each night and is part of The Battle For Angelus Prime. If you spot him, you can win an assassin figure of your own. We had a really good look, but we were unsuccessful.

Once we’d had a good look around the exhibition centre, the boys were keen to get something to eat. We decided to visit the on-site café, Bugman’s Bar. This is a large, airy bar with lots of space for people to hang out, play games; or do what we did, which was eat burgers. The food was really very good and reasonably priced, the boys both left clean plates. The staff were friendly, helpful and really made us feel welcome. I’d happily eat there again.

Between the shop and Bugman’s Bar was the Event Hall. This is a room where you can play games and reserve tables to play games at. You do need to bring your own miniatures and gaming equipment, but it looks like a fine place to do battle. Alas, we’d arrived empty handed, but the boys are keen to return at some point with their own armies.

With pocket money burning holes in their pockets, the boys spent a good hour or so exploring the shop (there’s a Warhammer Shop and a Forge World Shop). While they were deliberating, the painting table in the Warhammer shop opened and they grabbed a couple of seats. They have painting tables in the Warhammer shops on the high street, and it’s worth phoning ahead and booking a slot if you’re visiting, but the boys were keen to learn some new techniques.

The painting tables are really great for newbies. Although they’ve been painting miniatures for around a year now, they still have much to learn. You are given the choice of one of two miniatures to paint and access to all the paints you’d need. The tables are looked after by knowledgeable members of staff who make helpful suggestions, offer advice and can show you some painting techniques you might not have tried before.

The boys spent around an hour painting their miniatures. As there’s no crèche for tired mums, I decided if you can’t beat them, join them. So I pulled up a chair and tried my hand at painting my own figure. It turns out that if you’re in the same room when your child is watching hour after hour of painting tutorial videos on YouTube, occasionally some of that sticks in your head. Apparently I’m not terrible at painting miniatures. I’m happy I gave it a try, and if you’re a parent supporting you child’s hobby, then it’s fun to have a go, even if it’s just the once.

Again, I cannot fault the staff in the shop. They were so knowledgeable, helpful, friendly and clearly used to being spoken to by excitable children, like my two.

We spent around 5 hours in Warhammer World in total. There was plenty to see and do, and I really feel we made the most of it. The boys were sad they couldn’t play in the Events Hall, but there was scope for a small game in the shop, so it wasn’t the worst. It was a really fun day out. Both boys have said it was the highlight of their summer, and I don’t think you can get much higher praise than that.

Will we be back? Yes. Will we take our own armies next time? Also yes. Are the boys pestering me for a return already? Yes.

Warhammer World is in Nottingham, it’s brilliant and you can find out more on their website.
