👩🍳 How to Make Christmas Funfetti Cake (Step-by-Step)
Step 1: Prepare the Oven and Pan
Preheat your oven to 325°F (165°C). Grease a 9×13-inch baking pan with butter or cooking spray. You can also line the pan with parchment paper for easy removal.
Step 2: Make the Cake Batter
In a large mixing bowl, add the cake mix, milk, oil, egg whites, sour cream, and vanilla extract. Using a hand mixer or whisk, beat everything together until the batter becomes smooth and creamy. Make sure there are no dry lumps.
Step 3: Add the Sprinkles
Gently fold in the red and green sprinkles using a spatula. Do not overmix, as this can cause the colors to bleed into the batter.
Step 4: Bake the Cake
Pour the batter evenly into the prepared pan. Tap the pan gently on the counter to remove air bubbles. Bake the cake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
Step 5: Cool the Cake
Remove the cake from the oven and allow it to cool completely in the pan. This step is very important because frosting a warm cake will cause the frosting to melt.
🍥 How to Make Cream Cheese Frosting
- In a large bowl, beat the softened butter and cream cheese together until smooth and creamy.
- Add vanilla extract and mix well.
- Slowly add powdered sugar, one cup at a time, beating on low speed after each addition.
- Increase the mixer speed and beat for another 1–2 minutes until the frosting becomes light, fluffy, and silky smooth.
🎂 Assembling the Christmas Cake
Once the cake is fully cooled, spread the cream cheese frosting evenly over the top using a spatula or knife. Decorate with extra Christmas sprinkles to give the cake a festive holiday look.
🎄 Variations & Custom Ideas
