This easy DIY Minion Birthday Cake is the first in a series I’ll be doing over the next couple of months teaching you how to recreate this and other easy 3D cakes for your children’s birthdays!
Before we get started I want you to keep a couple of things in mind. First, I’m just a mom with no formal training. All of the cakes I have made are created using bits and pieces of tutorials that I have found across the web. Second, and more importantly, remember it’s just cake. Accidents will happen, but they can be fixed. I’ve had my fair share and in the end you would never know it.
How To Make Your Own DIY Minion Birthday Cake
While you can create these 3D cakes in a single setting, it’s best to do it over a couple of days. The directions I’ve outlined below will help ensure that the cake is complete before your child’s birthday party. It’s the same time frame I use for all of my cakes.
Supplies For Your DIY Minion Birthday Cake :
This list of supplies may look long, but several of the things listed are optional. I’ve included everything that I used for this cake from start to finish. Many of these items are also reusable for other cakes.
Three 8″ round cakes – using box mix or your favorite recipe
2 batches of your favorite homemade crusting buttercream frosting
One 8″ hemisphere cake, baked in a ball pan or Pyrex oven save bowl
1 one pound box of blue Fondant
Fondant Cutter & Embosser – used to make stitching pattern on the Minion’s overalls.
Fondant Rolling Pin or a traditional kitchen rolling pin
Fondant Mat – optional but will make things easier
Round Shape Cutter – Optional, but is what I used to make the goggle and eyes.
Plastic Pop Bottle Lid, plastic drinking straw (from McDonald’s) – used to make the eye
Wooden Cake Dowels – keeps your cake from shifting.
Bake Even Strips – optional
Parchment Paper – optional
Flower Nails – optional
Cake Plate or Silver Foiled Cake Base – I use the square silver foiled cake base for all of my cakes. They are easy to handle, strong, disposable and will last for several parties before I have to toss them.
Ultimate Professional Cake Decorating Set – Optional. I am including this kit because many of the tools I’ve mentioned above are included in it, and more. I purchased this kit when I decided I would be making my boys cakes and it has come in handy over the years.
Directions To Make DIY Minion Birthday Cake
1. Bake your cakes two days before the party. Cut circles out of parchment paper the size of your pan. Place a single flower nail in the middle of the pan and poke it through the parchment paper. Spray the cake pan with baking spray that has flour added in it. Fill each cake pan with 3 cups of batter. Wrap the outside of the pan with bake even strips that have been dampened with water. Place in the oven and bake according to the instructions in your recipe.
2. The following day, make your favorite crusting buttercream frosting. If you don’t have one here is the recipe that I use. I add a pinch of popcorn salt at the beginning; it helps cut down on the sweetness that American Buttercream is known for.
Color your frosting with a few drops of yellow food coloring. Mix and repeat until you get the color you like.
For those of you unfamiliar with the term crusting buttercream, all that means is that it will form a thin sugary crust when left sitting out. This is important and helpful.
3. Assemble your cakes. Spread a thin layer of frosting on one 8″ round cake board then place your first cake layer down on top. Give the cake just a little push so that it’s sticking well, but don’t push so hard that you crack it.
Measure 3/4 cup frosting and spread over the top of your first cake, then repeat between each layer. This will be your filling. Stack your second cake on top, push down slightly to make sure it sticks. Ensure each cake layer is even using a small level, so the finished product doesn’t look tippy. Repeat until your cake is completely stacked.
Use two wooden cake dowels to secure your layers in place. The dowels may need to be shortened so that when placed inside your cake it stops just beneath the surface. Otherwise it may create a funny pattern in your fondant or even make a small hole.
4. Spread a thin layer of frosting over the entire cake. It doesn’t have to look pretty. It is simply to keep the crumbs from making a mess out of the next layer of frosting. Let your cake stand for 15-20 minutes so that the frosting forms the crust you are looking for.
Give your cake a nice even second layer of frosting, no more than 1/4 inch thick. If your layer of frosting is too thick then the fondant will have a tendency to slide. Let your cake stand for 30 minutes to allow a crust to form.
How To Assemble Your DIY Minion Birthday Cake
We have finally come to the fun part! While your cake is sitting it’s time to create the details that will bring your minion to life!
- The Eye: One large white circle, use the round shape cutter to cut it out. Use the bottle cap to cut out the blue circle. Make the black pupal, using the drinking straw. Finally a small ball of white for the sparkle in his eye. As there are several layers to the eye, you will want to make each layer fairly thin but not paper-thin.
- The Goggle: I used the round shape cutter as the silver part of the goggle. However, you could make some gray fondant using a little less black food coloring. Roll it out, cut it into a strip then make a circle shape by putting the two ends together. Fondant will stick to itself if you use a very small amount of water brushed onto the two ends. This will need to set to dry and harden. The band of the goggle is a long strip of thinly rolled black colored fondant.
- The Arms: This is simply two long yellow fondant logs. Make them longer than you think you will need, you will cut them down to size later.
- The Hands: Start with two small, equal sized balls of black colored fondant. I freehanded them by molding each hand around my pointer finger to give it some shape. Then I used a small knife to cut slits all the way through it to make the fingers. Mold them into the shape that you like.
- The Legs: These are made the same way as the arms only out of blue fondant and much shorter.
- The Feet: I made them the same way as the hands using two small, equal sized balls of black fondant. Slightly flatten the ball with your thumb, then make a shoe shape. Using a small knife indent the bottom of the shoes, the part you see when looking at the cake, creating little lines to give them some character. Each shoe should be about the size of your thumb.
- Overalls: Your Minion’s overalls are created out of blue fondant. Make two panels, one for the front and one for the back. The front panel was a 3 1/4″ high and the back was 2 1/2″ high. You will need to find the right measurements for your own DIY Minion cake.
- Overall Straps: After placing your overall panels on the Minion you will need to measure from back to front to see how long your straps will need to be. When measuring, make sure to consider final placement of the straps.
- Buttons: The buttons are made out of the same blue fondant as the overalls. I used the bottle cap to create the them.
- Hair: I used black candles, I wanted the Minion’s hair to look like it was on fire when we lit the cake. It worked out great and was a very cool effect!
While the fondant pieces drying, move your cake to the foiled cake base. Open your fondant and begin to knead so that it becomes pliable. While you are working the fondant add in a few drops of yellow until you reach your desired color. If it becomes sticky sprinkle a little cornstarch on the fondant mat and it will help remove it.
Measure the height of your cake, then using the measurements on the fondant mat as your guide begin to roll out your fondant. Make your yellow fondant larger than you need so that you have plenty to work with. This will also allow you to have excess to trim creating a clean edge. Once your fondant is rolled out to the right size cover your cake with it. Use your fondant smoothers to gently but firmly smooth the fondant on your cake working in a circle from top to bottom. Gently pull the bottom of the fondant as you work around the cake to help keep it from wrinkling as you work. Once you have covered your cake in the yellow fondant it’s time to assemble the components.
To attach the fondant pieces to your cake use a small paint brush and a little water. The water will act like a glue and the fondant will stick to itself. Be careful when applying the fondant pieces as the colors can bleed onto one another, you don’t want to be moving them around once applied.
Begin with the placement of the eye and goggle, followed by the overalls making sure to leave room for your Minion’s mouth. Next add the legs, feet, arms and hands. You may need to make adjustments to the length of the arms and legs. To secure the arms to your cake; insert toothpicks into the ends and paint the fondant with a little water then push the toothpicks into the body of the cake. If the arms want to drupe you can support them with balls of fondant until they have dried and stiffened.
Once your arms are in place you can add the overall straps, buttons, and front pocket. Use the stitch wheel of your fondant embosser to create the stitching pattern on the overalls. Give your Minion a smile, add your child’s initial to the pocket, and button holes on your buttons using the edible black fondant marker. Finally, add the black candles to create the Minion’s hair.
