What is a Brownie Stack Birthday Cake? 

Behold! The brownie stack birthday cake! What is it, you ask? Well, my friends, it's all the rainbows and chocolate dreams that make brownies so incredible, stacked tall and proud. It’s the replacement birthday cake that you never knew you needed, an impressive birthday centrepiece to share with family and friends. The best part is you don’t even need to cut it. Just pop a candle in it, make a wish and select your favourite brownie! How good does that sound? 
 

Why You’ll Love this Brownie Stack Birthday Cake 

Besides the rainbows and chocolate dreams we’ve already discussed, the brownie birthday cake is just fun! You get to mix and match your favourite brownie types and flavour profiles while adding a little extra birthday flair. Another great benefit is you can make your brownies a few days in advance and keep them in the fridge until your big day. Storing them in the fridge makes them extra fudgy and delicious, plus there’s less work to do on your big day. 

 The Best Chocolate Brownie Recipes   

Chocolate brownies might be the one easy bake that is universally loved. Unless, of course, you don’t like chocolate, in which case there’s even a brownie just for you: it’s called a blondie, and it’s made with white chocolate, like our Milkybar® and Raspberry Blondie! But for all the chocolate lovers, brownies tend to steal the show.

We’ve got a brownie flavour for just about every taste, which makes today your lucky day. Love chocolate and mint? Try our Aero® Brownie or After Eight® Brownie – you can decorate these by sifting ½ tbsp icing sugar over the top and adding fresh mint leaves here and there. Caramel lovers will enjoy our Salted Caramel and Rolo® brownie recipes, while KitKat® and Smarties® brownies offer a little extra crunch. For something boldly different, check out our zesty Aero® Orange brookies.  
 

How to Make a Brownie Stack Birthday Cake

2. Arrange the brownies into a solid base and then begin to build up.  
3. Tuck additional treats into nooks and crannies and add a drizzle of any sauce last.

 Decorating Ideas for Brownie Stack Birthday Cake 

How simple or OTT you want to make your stack is up to you! Think sprinkles of freeze-dried berries, Aero® Bubbles, Milkybar®, KitKat® fingers, or a drizzle of melted chocolate. Tuck a few Rolo®s into the layers or add a splash of colour and chewy fun with a selection of Rowntree’s® sweets. Fresh berries are always a good idea for a fruity contrast to the fudgy flavours. Finish with a sprinkle of edible glitter or gold foil for extra pizazz, and you’ll have a brownie stack birthday cake worthy of a magazine cover.  

 Top Tips 

To build a sturdy stack, you need even-sized pieces of brownie. Choose a large enough platter and build your base layer in a circle pattern. Stack another layer on top and then continue building up. If things get a little shaky, use long wooden skewers cut to the right length and press down from the top through the stack to secure the structure. Just remember to remove them before serving!
