Why You Must Use Real Buttercream (Not Canned Frosting)
Before you grab your ingredients, there is one golden rule for this recipe: Do not use store-bought canned frosting. Store-bought canned frosting is formulated to be easily spreadable, which means it is too thin and soft. If you try to use it to span across separate cupcakes, it will sag into the gaps and your graduation cap will lose its structure.
Instead, use a thick, sturdy American Buttercream recipe. A proper homemade buttercream acts as a bridge, holding its shape across the gaps between the cupcakes and giving you that perfectly smooth, continuous cake-like surface.

What ingredients do you need for these Graduation Cupcakes?

21 pre baked cupcakes
1 American Buttercream recipe, split into two colors (I have a really great buttercream recipe here)
Gel food coloring

All of the detailed instructions are below but basically you will be gathering (or making!) premade cupcakes in the flavors of your choice with no frosting. Once you arrange the cupcakes in a diamond shape, you will be carefully icing all of the cupcakes into a graduation cap.

You can choose whatever color you like to match the your school colors or even your party theme colors.

What flavor cupcakes should I use?
I used vanilla cupcakes but you can use any flavor, a mix of flavors would be so fun!

FAQs
If your cupcakes are sliding on the board while you are trying to frost them, dot a tiny smear of buttercream frosting onto the bottom of each cupcake wrapper before pressing it onto your cake drum. This acts as a secure, edible “glue” to keep your diamond shape locked in place.
Yes! You can bake the cupcakes and mix your buttercream a day in advance. You can even fully assemble and frost the cap shape the evening before your party. Just keep the assembled board in a cool room or the refrigerator so the buttercream stays firm.
Achieving dark colors with gel dye can be tricky. To get a true black, dye your frosting brown first, mix it completely, and then add your black gel. For a vibrant school-spirit red, dye the frosting pink first before adding the red gel. This prevents you from over-saturating the frosting, which can ruin its consistency and give it a bitter taste.

Graduation Cupcakes For Your Graduate Celebrations
These graduation cupcakes make a perfect addition to any graduation celebration!
Ingredients
- 21 prebaked cupcakes
- 1 American Buttercream recipe, split into two colors
- Gel food coloring
Instructions
- Align the cupcakes like pictured making sure the top points in a V or arrow shape.
- The bottom will have a slightly more curved point.
- Fit a large piping bag with tip 1A and fill with the outside buttercream color (we used white)
- Applying even pressure squeeze a continuous circle on top of the cupcakes. It should be fluffy and thick. If it's not, you're not applying enough pressure.
- Do all of the outside cupcakes first. Then frost the center cupcakes as shown.
- Use an offset spatula to smooth the icing across the center cupcakes (this prepares the base for adding the second color.
- Grab a second piping bag and fit with a coupler and Wilton tip 5. Draw the top of an arrow across the top of the cupcakes as shown in the photo.
- Create a square to make the top of the cap.
- Then draw the bottom of the cap.
- Remove the tip and squeeze out the frosting to fill in the cap. Do the two sections separately. Smooth out the buttercream see notes section
- Fill in the second part and smooth out the buttercream.
- Line the third piping bag with a coupler and tip 16 with the first color and outline the cap.
- Switch the tip from 16 to 2 or 3. Make accent marks on the cap. Add congratulations message and you're done!
Notes
Cake drums are thicker than cake boards. If transporting the cupcakes I would opt for the drum not a board and they are on amazon.
Use gel food colors vs liquid to not change the consistency of the icing.
If you need really dark colors-it will be a two step process. For example if you need black dye the frosting brown first mix completely and then dye the brown frosting black. For red dye it pink, then red. Resist the urge to add a lot of food coloring-this will alter the taste and consistency and you won't achieve the color you want.
If your cupcakes move around you can glue them to the board with a little frosting.
Take your time if you've never done this before.
Tips for smoothing icing:
- Use an offset spatula that has been sitting in piping hot water. Whipe off the water and allow the heat from the spatula to smooth the icing.
- Allow the icing to crust over. Meaning it's dry to the touch. Place a piece of parchment paper on top and smooth the icing out with your hands on the parchment.
- Use a Plain white (zero decorations-no patterns) VIVA paper towel (only this brand works) and lay it over the icing once dry. Smooth out the frosting using hands.
*Use buttercream NOT canned frosting.
