Finley turned six this year, and when we started planning her birthday, she decided she wanted an art party. We ended up with nine kids, a giant canvas, a whole lot of paint, and individual cakes for the kids to paint with buttercream.

And somehow, it was also one of the easiest birthday parties we’ve done.

I think part of that was because we didn’t go crazy trying to make every single thing match the theme. There were no art-themed snacks or elaborate food table. I bought a $30 party kit from Amazon for most of the decorations, we served fruit, chips and dip, and I made the cake myself.

Most of our effort went into figuring out what the kids were actually going to do.

We had two main activities: painting a giant canvas together and painting their own pieces of birthday cake. Jake made the little wooden artist palettes from scrap we already had, brought home the fabric for the canvas from work, and we used backdrop stands and clamps we already owned to hang it.

It was cheap. It was messy. And all nine kids were entertained pretty much the entire time.

I’d absolutely throw this party again.

What we actually bought for the party

I love a party kit. I do not love buying plates from one listing, cups from another, a banner somewhere else, and then realizing three days before the party that apparently I also need 47 tiny paint-themed decorations.

I bought a paint party decoration kit from Amazon for about $30 and called it good. It came with basically all of the themed decorations we needed, and for $28.99, it was probably the best money I spent on the party.

The other things I bought were:

• Colorations washable tempera paint
• no-spill paint cups with brushes
• cake-decorating brushes
• Pixie Dust natural food coloring
• plastic palette knives

I also put all of the supplies into my Art Birthday Party Amazon list so they’re in one place. I added ready-made wooden palettes and the canvas drop cloth I had originally planned to buy, too.

We made our palettes from scrap wood, but there’s a ready-made option on the list if making 16 tiny wooden palettes isn’t your idea of a good time. Our fabric was free, but I included the canvas I originally planned to buy if you don’t happen to have a husband who can casually bring home a 12-foot piece of fabric from work. 😂

One thing I almost bought twice: paintbrushes. I had a separate set in my cart before I realized the no-spill paint cups already came with brushes. Read the listing before you order everything—I almost spent extra money for absolutely no reason.

The rest we either made ourselves or already had.

The paint-your-own cake activity

This was the idea I was most excited about, and thankfully it actually worked the way it did in my head.

Each kid got a big rectangular piece of vanilla cake frosted with white buttercream. That was their “canvas.” Then I put five dollops of colored buttercream around their wooden artist palette—red, orange, yellow, green and blue—and gave them cake-decorating paintbrushes and little plastic palette knives.

Then I let them have at it.

And they really did paint them. They mixed colors, used the brushes and palette knives, smeared frosting everywhere and made completely different cakes.

I had considered putting sprinkles out too, and I am SO glad I didn’t. I think if I had, half the kids would have dumped a mountain of sprinkles on top and called it finished. 😂

Without them, they actually played with the frosting colors and got creative.

And yes, they ate their paintings afterward.

I made almost everything ahead

I knew I didn’t want to be baking multiple cakes the morning of a birthday party, so I started these the weekend before.

I baked two 9×13 vanilla cakes, let them cool, wrapped them really well and froze them.

I used my vanilla cake recipe, which is a moist, slightly denser vanilla cake. We actually got several comments at the party about how moist it was, and the texture worked really well for this because the pieces held up while a bunch of six-year-olds attacked them with paintbrushes.

The night before the party, I made my buttercream frosting. My recipe uses both butter and shortening, and I made enough to frost the cakes white plus five additional colors for painting.

I used the Pixie Dust powdered natural food coloring for the red, orange, yellow, green and blue. I really wasn’t sure how well powdered colors were going to work in buttercream, but I was pleasantly surprised. We got really pretty colors without needing a ridiculous amount.

Wrapping the buttercream saved a ton of fridge space

So I put each color onto a piece of plastic wrap, rolled it into a little log and refrigerated it that way.

The next morning I could pull all of the colors out together, and I wasn’t trying to find room for a stack of mixing bowls between everything else I had shoved into the fridge for the party.

Highly recommend.

Frost the cake before you cut it

The morning of the party, I pulled the buttercream out of the refrigerator around 7 a.m. It needed a few hours to come back to room temperature before it was soft enough to spread easily.

Around 10:30, I frosted the whole sheet cake with white buttercream and put it into the refrigerator.

One extra tip if you don’t usually decorate cakes: if you want the flattest surface possible, flip the cake over and frost the bottom. The bottom is already perfectly level, so it makes a much easier little canvas than the rounded top.

It chilled for about two hours before I cut it into eight big rectangles.

That worked SO much better than trying to cut a cake with freshly spread buttercream. Once the frosting was cold and firm, I could make the cuts without dragging soft frosting all over the top.

I made two sheet cakes because I wasn’t sure exactly how much I would need. I ended up needing the first cake plus one piece from the second, so now I have almost an entire birthday cake headed for the freezer.

Future us gets birthday cake for no reason. I see no downside here.

Party-time setup took about five minutes

I waited until the kids were actually ready to paint before setting the palettes up outside.

It was August. There were bugs. I didn’t spend all that time making cake from scratch just to offer the local flies a buffet.

Since everything was already made, it took me maybe five minutes.

Cake on each palette, five dollops of colored buttercream, brushes and palette knives out, done.

That was it.

The wooden artist palettes

Jake made 16 palettes so we’d have extras.

They started as roughly 12×9-inch rectangles. He screwed the pieces together at the corners, drilled the thumb holes, trimmed them into the palette shape and sanded the edges really well so there was nothing rough for the kids to catch their hands on.

We didn’t stain or seal them.

I put the cake directly on ours, but if you’d rather not put food directly on unfinished wood, you could easily cut a little piece of parchment to fit underneath the cake.

You also absolutely do not have to make wooden palettes to do this activity. A regular plate will still result in a kid smearing frosting all over a piece of cake just fine.

But we had the scrap material, Jake could make them, and they ended up being one of my favorite parts of the setup.

We’d definitely make them again.

The giant canvas painting

The other big activity was even simpler.

Jake brought home a piece of fabric from work that was somewhere around 10–12 feet long and about 5 feet tall.

We already own backdrop stands, so we hung the fabric from those with wood clamps and put some old bricks along the bottom to keep it from moving around.

Very sophisticated equipment over here.

For the actual painting, I bought Colorations washable tempera paint and no-spill paint cups. The cups came with the brushes, which is why you won’t see a second set of regular paintbrushes on the supply list.

We kept this part really simple. We didn’t give them a bunch of supplies or instructions. We put out the paint, gave them brushes and let them paint whatever they wanted.

It kept them entertained way better than I expected.

By the time they were finished, the giant white piece of fabric was completely covered in their artwork.

We’re keeping the finished canvas

We’re folding up Finley’s finished canvas and keeping it for her.

Our original plan was to have all of the kids sign it with a Sharpie when they were finished, almost like one giant birthday card.

We remembered to have exactly one kid sign it.

So. Nailed that part.

But we loved the whole thing enough that now we’re talking about making the birthday canvas a tradition for all three kids. We’d probably make future ones a little smaller, have everyone paint and sign them, and save each one as a keepsake from that year’s birthday.

Next time, the Sharpie is going somewhere impossible for me to forget.

We kept the food really simple

What I would do differently

Honestly, not much.

I would remember the Sharpie.

I also might think through cake storage a little earlier. I didn’t buy disposable cake boxes because I knew I was going to throw them away afterward, and I’d rather do a little extra work than spend money on something just to toss it.

That meant I still had the adult cake to decorate the morning of the party, along with finishing the kids’ cakes.

But I am also a Last-Minute Larry by nature, so I’m not going to pretend better cake boxes would suddenly turn me into a person calmly drinking coffee in a spotless kitchen three hours before a birthday party.

The important stuff was ready.

I’d bake and freeze the cakes ahead again. I’d make and color the frosting the night before. I’d refrigerate the frosted sheet cake before cutting it. I’d skip the sprinkles. We’d make the palettes again.

And I definitely want to do the canvas again.

A fun kids’ birthday party doesn’t have to cost a fortune

I think this party changed how I want to approach birthdays a little bit.

It seems like so much of birthday-party planning has become about decorations and making everything look right. The themed food, the backdrop, the balloon arch, the perfectly coordinated everything.

And I like cute decorations too. I bought the party kit for a reason.

But the kids don’t need 37 things to look at. They need something to do.

For this party, we kept the decorations easy, served really basic food and put most of our effort into two activities.

The kids painted cake. They painted a giant canvas. They got messy. They stayed entertained.

And everyone kept commenting on how creative the party was and how much of it we’d managed to make ourselves without spending a ton of money.

Meanwhile, it was probably one of the easiest birthday parties we’ve ever thrown.

That feels like a pretty good trade to me.

If you’re planning an art birthday party, use what you already have, make the things that make sense for you to make, buy the things that save you enough work to be worth buying, and give the kids something fun to do.

They really don’t care whether their fruit tray matches the theme.
