We have lots of family birthdays during the summer. We recently celebrated some of those birthdays with two of our nephews. Their actual birthdays are a few days apart so they had a joint party. They are big fans of Minecraft video games and Youtube videos. So it was no surprise when they asked for a Minecraft birthday cake. With everything in the game being squares, the cake design is pretty simple but has a surprise checkerboard pattern on the inside. I made them each a cake version of their favorite characters, Herobrine and the wolf.
To Make the Checkerboard Pattern Cake:
First, I baked 4 layers of chocolate cake and 4 layers of vanilla cake dyed green and mixed up a double batch of buttercream. Each of the heads is 4 square layers of cake to make a cube like in the game. Yes, it was a lot of cake! If you are only making one cake, you only need half as much cake though. I trimmed each layer of cake down because my pans were rounded on the corners. The cake trimmings can be frozen to use later for cake pops or ice cream cake. To create the checkerboard pattern inside the cake I followed this tutorial.
After stacking and crumb coating both cakes, I put placed them in the fridge for about an hour to firm up.
Now for the fun part, decorating!
Supplies for the Herobrine Minecraft Birthday Cake with Light-Up Eyes:
1 crumb coated cube cake
icing tinted a peachy skin color
dark brown fondant
smoothie straws or regular straws
1 small set of battery powered fairy lights
cardstock or construction paper
two-inch square cookie cutter
Making the Eyes Glow:
To make the eyes glow I added fairy lights inside the cake. This is optional but really nice touch if you do it. First cut down two of the smoothie straws to the length of the cake then carefully push the straws through the cake where you want to eyes to go.
Next, cut two more pieces of the straws and thread the fairy lights through them. These straws help hide the lights on the backside of the cake and protect them from direct contact with the icing.
Before I put the lights into the cake, I folded them down so about four of the tiny bulbs were grouped together which helped make it brighter than if just one of the bulbs were by itself. Now that the bulbs are grouped together, push the bulbs it inside the straw until almost to the very end so that the glow of the lights will be strong.
Now on the backside of the cake, slide one of the smoothie straw pieces to where the string of lights comes out of the eye on the back and push it into the cake directing the light string to the other eye.
Then carefully fold the string again so that four little bulbs are together and then slide it into the other straw just like the first eye. Then to finish hiding the string, slide the last piece of smoothie straw down where the string comes out of the eye and then push it down into the icing effectively covering the lights and directing them away from the cake. Make sure that the straws are pushed into the cake really well so that they can be hidden when the icing was smoothed over them. (Make sure to remove the lighting before cutting the cake to serve!)
Now that the lights for the eyes are hidden, frost the cake with the peachy skin color icing. When the cake is completely covered, I used a warmed straight edge to get the icing as smooth as possible. To warm the straight edge, hold it under a hot faucet until it’s warm to the touch then dry it off before smoothing over the cake. Rewarm every few swipes. It can be somewhat tedious.
Use the tip of a knife to carefully remove any icing that got into the straws on the face. On the back of the cake though make sure the icing completely covers the straws that are protecting the fairy lights. Then chill the cake again for about 30 minutes before adding the fondant hair and face pieces.
Adding the Details to Herobrine:
To make the hair, I measured the cake sides and top. The icing layers add a few inches to the dimensions so it wasn’t exactly six inches anymore. Then cut templates for the hair from sturdy paper to use to cut out the fondant.
After the templates are made, roll out the dark brown fondant to about quarter inch thick and cut the pieces of hair. To keep the fondant from sticking while rolling it out, sprinkle a little cornstarch on your surface. To attach the pieces to the cake, Brush a little bit of water on the back and place on the cake. Use a fondant smoother to help smooth them out.
For the eyes, roll out the white fondant to a quarter inch thickness, and cut 1 two-inch square. Cut the square in half. Use a knife to round the corners a little. Brush a little water on the backside of the fondant and place on the face over the lights placed in the eyes.
For the nose and mouth, mix a little bit of white fondant with the brown to create a brown that is just a few shades lighter than the hair. Roll out the fondant to about quarter inch thickness and cut 2 two-inch squares. Cut each square in half and then round the corners with the knife same as with the eyes. Brush the back of the fondant pieces with water and arrange on the cake to make the nose and mouth. Turn on the fairy lights and voila, Herobrine with real glowing eyes.
Note: Herobrine is not really a character in the Minecraft game itself but a character in a community made story. My son had to explain who he is to me. This Minecraft wiki page explains his character further. He basically looks like the Minecraft character Steve but his eyes are all white and they glow. If making his eyes light up isn’t something you want to do, it can be skipped. He would look just as accurate with white eyes. He is a villain and doesn’t always smile but I chose to have him smile. If you want to make a Minecraft Steve Birthday Cake, you can skip the lights and add a blue square to the eye coloring. This could easily be made to look like a Minecraft Creeper Birthday Cake too. Just use green icing, leave off the fondant hair and make the face pieces out of black fondant.
Put Herobrine in the fridge to stay cold and start on the Wolf Minecraft Birthday Cake.
Supplies for the Wolf Minecraft Birthday Cake:
To make the 3D ears and nose:
First, ice the cake with the gray color icing. Again using a warmed straight edge to get the icing as smooth as possible.
Next, cut 4 two-inch squares from the rice crispy treats. Set aside. Trim the skewers to the height of the cake or a little shorter. Push 2 skewers each into the squares. These will be the ears. Stack 2 of the squares together to make a cube. This will be the nose and mouth. Push 3-4 skewers into the cube. Next, push the rice crispy ears into the top of the cake and the mouth into the front.
Finally, coat with icing and smooth with the straight edge or small offset spatula.
Adding the details to the Minecraft Wolf:
Now for the fondant details, begin by mixing a little of the white, black, and brown fondant together to make a brownish gray color.
After your color is mixed, roll out each of the fondants and cut out two-inch squares as listed below:
For the eyes and nose, cut 1 of the black squares and 1 of the white square into 4 smaller squares. Cut the gray-brown square into 2 rectangle halves. Cut one of the rectangles in half again to create 2 smaller squares. Brush a bit of water on the back of all these pieces. Then place the gray-brown rectangle directly over the cube of rice crispy. Then 2 of the black squares on either side of the rectangle. Then place 2 of the white squares on either side of those. Place 1 gray-brown square on top of the rice crispy cube. Then place 2 of the black squares on the top and front of the cube.
For the mouth and ears, cut the remaining 2 black squares into four strips each. Again, brush the backs with a little bit of water. Then place 3 strips along the bottom edge of the rice crispy cube to create the mouth. Lastly, place 3 strips each along the outer edge of the ears.
For the bone which totally optional to add, roll out the fondant pretty thickly and use a bone cookie cutter to cut a bone shape, then cut the shape in half. To attach the bone to the cake, stick toothpicks into the cut side and carefully push the bone pieces into either side of the mouth. And there you have a Minecraft Wolf Cake.
These cakes turned out great. The boys were just floored when they saw that they each had their own Minecraft Birthday Cake. The light up eyes and the checkerboard pattern on the inside just wowed them even further.
Remember, you don’t have to do both heads or even the checkerboard pattern inside. In addition, making just a few changes to the coloring, the design of these cakes can easily be adjusted to make other Minecraft characters like Steve or the pig. Now it’s your turn to go get your Minecraft Birthday Cake on!
