Ingredients for Birthday Cake Donuts

Donuts:

1 ¼ cup all-purpose flour
1 tsp baking powder
1 large egg
½ cup granulated sugar (or substitute with ⅓ cup honey)
4 tbsp unsalted butter, melted
1 tsp birthday cake extract
⅓ cup milk (regular or almond milk)
⅛ tsp salt

Frosting:

1 cup powdered sugar
1 tbsp unsalted butter
1 ½ tbsp heavy whipping cream
½ tsp vanilla extract
Rainbow nonpareil sprinkles

How to Make Birthday Cake Donuts Step-by-Step

Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C). Grease a donut baking pan with butter or nonstick spray to ensure the birthday cake donuts release easily after baking.

Step 2: Mix the Donut Batter

In a large microwave-safe bowl, melt the butter. Stir in the sugar and salt. Whisk in the egg, then mix in the birthday cake extract and milk. Gently fold in the flour and baking powder until smooth. The batter should be thick and scoopable, not runny.

Step 3: Fill and Bake

Spoon or pipe the batter into your donut pan, filling each mold about ¾ full. Bake for 10 minutes, or until the birthday cake donuts spring back when lightly touched. Allow them to cool in the pan for 5 minutes before transferring to a wire rack.

Step 4: Make the Frosting

While the donuts cool, melt the butter in a microwave-safe bowl. Whisk in the vanilla extract, powdered sugar, and heavy cream until smooth and spreadable. Add water 1 tsp at a time if the frosting is too thick.

Step 5: Frost and Decorate

Once the birthday cake donuts have fully cooled, spread the glaze over the tops with a spatula. Immediately decorate with rainbow sprinkles to lock in the party vibes.

Tips for Perfect Birthday Cake Donuts Every Time

Don’t Overmix: Mix the batter just until the ingredients are combined to avoid tough donuts.
Use a Piping Bag: Transfer batter to a piping bag (or zip-top bag with the tip cut off) for easy and mess-free filling.
Let Them Cool Completely: Frosting will melt and slide off if the donuts are still warm.
Double the Batch: These go fast! Make a double batch for larger gatherings or freeze extras for later.

Creative Ways to Enjoy Birthday Cake Donuts

These birthday cake donuts are delightful just as they are, but you can get creative with how you serve them:

Mini Donuts for Party Favors: Use a mini donut pan to make bite-sized versions, perfect for gifting or kids’ parties.
Add a Candle: Make one special donut the “cake” and add a candle on top for a birthday breakfast.
Serve with Ice Cream: Slice in half and sandwich ice cream in the center for an indulgent twist.
Glaze Variations: Try strawberry, chocolate, or lemon glaze instead of vanilla for fun flavor variations.

How to Store Birthday Cake Donuts

Birthday cake donuts can be stored in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days or freeze (unfrosted) for up to 1 month. To serve from frozen, let them thaw at room temperature, then frost and decorate.
