🛒 Ingredients
For the Funfetti Sponge Cake:
- ¾ cup (95g) all-purpose flour
- 1 tsp baking powder
- ¼ tsp salt
- 3 large eggs (room temperature for better volume!)
- ¾ cup (150g) granulated sugar
- 1 tsp vanilla extract
- ¼ cup (60ml) milk
- 2 tbsp vegetable oil (keeps the cake moist!)
- ¼ cup (40g) rainbow sprinkles (jimmies work best—avoid nonpareils! 🎉)
For the Vanilla Buttercream Filling:
- ½ cup (113g) unsalted butter, softened
- 1 ½ cups (180g) powdered sugar
- 1 tsp vanilla extract
- 2 tbsp heavy cream or milk (adjust for spreadable consistency!)
- ¼ cup (40g) rainbow sprinkles
For Topping:
- Powdered sugar for dusting
- Whipped cream or frosting for decorating (optional! 🎂)
- Extra rainbow sprinkles for garnish
🔥 Directions
1️⃣ Preheat & Prep
- Preheat your oven to 350°F (175°C).
- Grease a 10×15-inch jelly roll pan, then line it with parchment paper and grease the paper. (This prevents sticking!)
2️⃣ Make the Funfetti Sponge Cake
- In a bowl, whisk together flour, baking powder, and salt. Set aside.
- In a large mixing bowl, beat eggs and sugar on high speed for 3-4 minutes, until pale and thick.
- Add vanilla extract, vegetable oil, and milk, mixing until combined.
- Gently fold in the dry ingredients until just combined—don’t overmix!
- Carefully fold in rainbow sprinkles, being careful not to overmix (this prevents color bleeding).
- Pour the batter into the prepared pan and spread evenly.
3️⃣ Bake & Roll the Cake
- Bake for 10-12 minutes, or until the top is set and springs back when lightly touched.
- While still warm, flip the cake onto a clean kitchen towel dusted with powdered sugar.
- Carefully peel off the parchment paper, then roll the cake up inside the towel (starting from the short side).
- Let it cool completely in the towel—this prevents cracks!
4️⃣ Make the Vanilla Buttercream Filling
- In a bowl, beat butter until smooth and creamy.
- Add powdered sugar and vanilla extract, mixing until fluffy.
- Slowly add heavy cream or milk until smooth and spreadable.
- Gently fold in rainbow sprinkles for that extra funfetti effect! 🎉
5️⃣ Fill & Roll the Cake
- Gently unroll the cooled cake, then spread the buttercream filling evenly over the surface.
- Carefully roll the cake back up (without the towel), placing it seam-side down.
- Refrigerate for 30 minutes to firm up before slicing.
6️⃣ Add Toppings & Serve
- Dust with powdered sugar, then decorate with whipped cream, extra sprinkles, or frosting. 🎂✨
- Slice and enjoy your fun, festive Funfetti Birthday Cake Roll! 🎊🎉
🎂 Helpful Tips & FAQ
Why did my cake crack when rolling?
