Ingredients You Need

• All-purpose flour: 2.5 cups or 300 g (King Arthur gives consistent lift; swap a 1:1 gluten-free blend if needed)
• Baking powder: 2.5 tsp (fresh matters for rise)
• Fine sea salt: 0.5 tsp
• Granulated sugar: 1.75 cups or 350 g
• Unsalted butter: 0.75 cup or 170 g, room temp (Kerrygold or Challenge hold structure; use dairy-free stick butter for swap)
• Neutral oil: 2 tbsp (canola or grapeseed keeps the crumb extra moist)
• Large eggs: 4, room temp
• Pure vanilla extract: 1 tbsp (use a good one like Nielsen-Massey; clear imitation vanilla works for a paler crumb)
• Whole milk: 1 cup or 240 ml, room temp (oat milk or lactose-free milk also work)
• Sour cream: 0.5 cup or 120 g, room temp (Greek yogurt works)
• Rainbow jimmies sprinkles: 0.5 cup, plus extra for garnish (use jimmies, not nonpareils, to prevent color bleed)

Buttercream and decor

• Unsalted butter: 1.5 cups or 340 g, room temp
• Powdered sugar: 5 to 6 cups or 600 to 720 g, sifted
• Heavy cream: 4 to 6 tbsp
• Vanilla extract: 2 tsp
• Pinch of salt
• Gel food coloring: pastel pink, pale yellow, or soft blue
• Optional candy eyes or small fondant circles, tiny pink fondant triangle or candy for nose, and candles

Equipment

• Two 8-inch round cake pans, parchment, nonstick spray or butter-flour mix
• Stand mixer or hand mixer, two mixing bowls, rubber spatula
• Wire racks, serrated knife, offset spatula, piping bags
• Piping tips: small star tip or grass tip for plush texture, round tip for borders
• Bench scraper or straight spatula

How to Make Jellycat Birthday Cake Recipe

Prep the pans and oven

1. Heat the oven to 350°F.
2. Grease two 8-inch pans, line with parchment rounds, then grease the parchment.
3. Stir flour, baking powder, and salt in a bowl.

Mix the vanilla funfetti batter

1. Beat butter and sugar on medium-high for 3 minutes until pale and fluffy.
2. Add oil, then beat for 15 seconds.
3. Add eggs one at a time, mixing 20 seconds after each. Scrape the bowl.
4. Mix in vanilla.
5. On low, add half the dry mix, then all the milk and sour cream, then the rest of the dry mix. Mix just until smooth.
6. Fold in sprinkles with a spatula. Aim for even streaks without overmixing.

Bake the layers

1. Divide batter evenly between pans and smooth the tops.
2. Bake 25 to 30 minutes, until a toothpick comes out with a few moist crumbs.
3. Cool in pans 10 minutes, then turn out onto racks and cool fully, 45 to 60 minutes.

Whip the buttercream

1. Beat butter on medium-high for 2 minutes until creamy.
2. Add 3 cups powdered sugar, salt, and 2 tbsp cream; beat on low until combined, then on medium for 1 minute.
3. Add remaining sugar to reach a spreadable but sturdy consistency, plus more cream as needed.
4. Beat 2 minutes until fluffy and smooth.
5. Tint most of the frosting a soft pastel. Keep a small bowl of white frosting for details.

Assemble and decorate

1. Level domes with a serrated knife if needed.
2. Set the first layer on a board, top with about 1 cup frosting, and spread to the edges.
3. Set the second layer on top, then coat the whole cake with a thin crumb coat. Chill 15 minutes.
4. Apply a thicker coat of pastel frosting and smooth lightly.
5. Fit a piping bag with a small star or grass tip. Pipe short dabs all over the sides and top to mimic plush fur.
6. Add candy or fondant eyes and a tiny pink nose near the bottom third to give a friendly face.
7. Sprinkle a halo of jimmies around the base or top edge, then add candles.

Tips & Common Mistakes

• Bring ingredients to room temp, or the batter can look curdled and bake unevenly.
• Use jimmies sprinkles, not nonpareils, or the colors will bleed.
• Weigh flour if possible, or spoon and level; extra flour makes a dry crumb.
• Do not overmix after adding flour; stop as soon as the batter turns smooth.
• Grease, line, then grease again to guarantee clean release.
• Cool layers fully before frosting to prevent melting and sliding.
• Keep buttercream slightly firm for texture piping; add cream a teaspoon at a time.
• Practice a few piping dabs on parchment before you move to the cake.
• Add facial features low and centered; too high can look awkward in photos.
• Slice with a hot, dry knife for tidy wedges.

Variations I've Tried

• Chocolate funfetti: Swap 0.5 cup flour for 0.5 cup cocoa powder and add 2 tbsp milk.
• Strawberry milk cake: Replace milk with strawberry milk and tint frosting pale pink.
• Lemon confetti: Add 1 tbsp lemon zest and 1 tsp lemon extract; finish with yellow sprinkles.
• Gluten-free: Use a 1:1 gluten-free flour blend and add 1 extra tbsp milk.
• Dairy-free: Use dairy-free butter sticks, oat milk, and a vegan sour cream alternative.
• Cupcakes: Bake 20 to 22 minutes, then pipe plush swirls and add mini faces.

How to Serve

Slice the cake while cold for clean edges, then let slices sit 10 minutes so the crumb turns soft and bouncy. Pair with cold milk, hot coffee, or a mug of black tea. Add a scoop of vanilla ice cream or fresh strawberries if you want a little extra party on the plate.

Make-Ahead and Storage

• Bake layers up to 2 days ahead, wrap well, and chill. You can also freeze layers up to 2 months; thaw wrapped in the fridge overnight.
• Store the frosted cake at cool room temp up to 1 day, or refrigerate up to 5 days.
• Keep slices airtight to prevent fridge funk.
• Serve chilled slices after a 20-minute counter rest, or warm a slice in the microwave for 8 to 10 seconds to soften the crumb and frosting.

Total Time 2 hours hrs

Servings: 12

Course: Dessert

Ingredients

  

• 2 1/2 cups all-purpose flour
• 2 1/2 teaspoons baking powder
• 1/2 teaspoon fine sea salt
• 1 3/4 cups granulated sugar
• 3/4 cup unsalted butter, room temperature
• 2 tablespoons neutral oil (such as canola or grapeseed)
• 4 large eggs, room temperature
• 1 tablespoon pure vanilla extract
• 1 cup whole milk, room temperature
• 1/2 cup sour cream, room temperature
• 1/2 cup rainbow jimmies sprinkles, plus extra for garnish

• 1 1/2 cups unsalted butter, room temperature
• 5-6 cups powdered sugar, sifted
• 4-6 tablespoons heavy cream
• 2 teaspoons vanilla extract
• 1 pinch salt
• gel food coloring in soft pastel shades
• candy eyes or small fondant circles (optional)
• tiny pink fondant triangle or small candy for the nose (optional)
• birthday candles

Instructions

 

1. Heat the oven to 350°F (175°C).
2. Grease two 8-inch round cake pans, line the bottoms with parchment rounds, then lightly grease the parchment as well.
3. In a medium bowl, whisk together the flour, baking powder, and fine sea salt; set aside.

1. In a large mixing bowl, beat the butter and granulated sugar on medium-high speed for about 3 minutes, or until very pale and fluffy.
2. Add the neutral oil and beat for about 15 seconds to combine.
3. Beat in the eggs one at a time, mixing for about 20 seconds after each addition and scraping down the bowl as needed.
4. Mix in the vanilla extract until evenly combined.
5. With the mixer on low speed, add about half of the flour mixture, then all of the milk and sour cream, followed by the remaining flour mixture. Mix just until the batter is smooth and no dry streaks remain.
6. Use a spatula to gently fold in the rainbow jimmies sprinkles, aiming for even streaks without overmixing so the colors don’t bleed.

1. Divide the batter evenly between the prepared pans and smooth the tops with a spatula.
2. Bake for 25 to 30 minutes, or until the cakes are lightly golden and a toothpick inserted in the center comes out with a few moist crumbs attached.
3. Let the cakes cool in the pans for 10 minutes, then turn them out onto wire racks, peel off the parchment, and cool completely, 45 to 60 minutes.

1. In a large bowl, beat the butter on medium-high speed for about 2 minutes, until creamy and smooth.
2. Add about 3 cups of the powdered sugar, the salt, and 2 tablespoons of heavy cream. Beat on low speed until combined, then increase to medium speed and beat for 1 minute.
3. Gradually add the remaining powdered sugar until the frosting is spreadable but sturdy, adding more cream 1 tablespoon at a time as needed to reach a smooth, pipeable consistency.
4. Beat the frosting for another 2 minutes until very fluffy. Tint most of the frosting a soft pastel shade with gel food coloring, leaving a small portion white for details.

1. If needed, use a serrated knife to level any domed tops from the cooled cake layers.
2. Place the first layer on a serving board or cake stand. Spread about 1 cup of pastel buttercream evenly over the top, going right to the edges.
3. Set the second cake layer on top, cut side down. Cover the entire cake with a thin crumb coat of frosting to seal in any loose crumbs, then chill for about 15 minutes to set.
4. Apply a thicker final coat of pastel frosting over the chilled cake and lightly smooth it with an offset spatula or bench scraper.
5. Fit a piping bag with a small star or grass tip and fill with pastel frosting. Pipe short dabs all over the top and sides of the cake to create a plush, fur-like texture.
6. Add candy eyes or small fondant circles and a tiny pink fondant triangle or candy for the nose near the bottom third of the cake to give it a friendly plush face.
7. Sprinkle extra rainbow jimmies around the base or along the top edge of the cake, then finish with birthday candles before serving.
