Directions: Funfetti Bundt Cake Birthday Cake

Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Grease and flour your bundt pan thoroughly to prevent sticking. You can use a non-stick spray or butter and flour.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, and salt. This step ensures that the leavening agent is evenly distributed throughout the flour.
Step 3: Cream Butter and Cream Cheese
In a large mixing bowl, use your electric mixer to cream together the unsalted butter and cream cheese until smooth and fluffy, about 2-3 minutes.
Step 4: Add Sugar and Vanilla
Gradually add the granulated sugar and continue beating until the mixture is light and fluffy. Mix in the vanilla extract until well combined.
Step 5: Incorporate Eggs
Add the eggs one at a time, ensuring each is fully incorporated before adding the next. Scrape down the sides of the bowl as needed.
Step 6: Combine Wet and Dry Ingredients
With the mixer on low speed, alternate adding the flour mixture and the whole milk and canola oil. Start and end with the flour mixture. Mix until just combined, being careful not to overmix.
Step 7: Fold in Sprinkles
Gently fold in the rainbow sprinkles using a rubber spatula until evenly distributed throughout the batter.
Step 8: Bake the Cake
Pour the batter into the prepared bundt pan, smoothing the top if necessary. Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted in the center comes out clean.
Step 9: Cool the Cake
Once baked, allow the cake to cool in the pan for about 10 minutes. Then, carefully invert it onto a wire rack to cool completely.
Step 10: Make the Frosting
In a medium bowl, beat the cream cheese and unsalted butter until smooth. Gradually add the sifted confectioners’ sugar, mixing until well combined. Add the vanilla extract, salt, and milk, adjusting the consistency as needed.
Step 11: Frost the Cake
Once the cake is completely cooled, place it on a serving plate. Use an offset spatula to spread the cream cheese frosting over the top and let it drip down the sides.
Step 12: Decorate
Finish off by generously sprinkling rainbow sprinkles all over the frosted cake. Add optional rainbow nonpareils or sparkler candles for a festive touch!
Vegan & Vegetarian Swaps
If you’re looking to make this Funfetti Bundt Cake Birthday Cake vegan or vegetarian, consider these swaps:
- Butter: Use vegan butter instead of unsalted butter.
- Eggs: Substitute each egg with 1/4 cup of unsweetened applesauce or a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water).
- Milk: Replace whole milk with almond milk, soy milk, or any plant-based milk.
- Cream Cheese: Use a vegan cream cheese alternative for the frosting.
What I Learned Testing
Throughout the testing of this Funfetti Bundt Cake Birthday Cake, I discovered that careful measuring is crucial for achieving the right texture. Overmixing the batter can lead to a dense cake, so mixing until just combined is the way to go. Additionally, letting the cake cool completely before frosting is essential to prevent the frosting from melting off. Finally, the choice of sprinkles makes a significant difference in the cake’s appearance, so be sure to use the right type.
Cooling, Storing & Rewarming
Once your Funfetti Bundt Cake Birthday Cake is baked and frosted, allow it to sit at room temperature for up to 2 days, covered with plastic wrap or in an airtight container. If you need to store it longer, refrigerate it for up to a week. To rewarm, simply slice a piece and microwave it for 10-15 seconds for a delightful, soft texture.
Frequently Asked Questions
