Equipment & Ingredients
To make this birthday cake blondies you will need these ingredients:
- Butter
- White Chocolate Chips
- Eggs
- White Sugar
- Vanilla Extract
- Almond Extract
- All Purpose Flour
- Salt
- Confetti Sprinkles
- Powdered Sugar
- Heavy Cream
- Pink Food Dye
As for the equipment, the list is much shorter! You will just need:
Whip Up the Blondie Batter
Pre heat the oven to 300 degrees Fahrenheit. To start the blondie batter heat up the butter in the microwave or a saucepan. In a bowl with the white chocolate chips, pour the hot butter on top and let sit for 5 minutes. Then stir the chocolate chips until they are fully melted and smooth.
In a separate bowl add the eggs and whip with a whisk or hand mixer until foamy. Then add in the sugar, vanilla extract and almond extract, whipping once again and combined.
The whipped, foamy eggs will help the birthday blondies rise since this recipe doesn’t need any leaveners such as baking soda and powder.
Now go ahead and mix together the white chocolate and whipped egg mixture. Fold together using a rubber spatula. Then go in with the dry ingredients of salt and flour, folding together once again until combined. Now go in with the confetti sprinkles, folding the birthday cake blondies batter one more time to have the finished batter.
Bake The Birthday Blondies
Pour the batter into a 9×9 baking dish lined with parchment paper. Bake in the oven for 25 minutes or until a toothpick is inserted and comes out clean. As shown in the picture above you should notice a nicely browned blondie. Let these cool for at least 30 minutes while you start making the buttercream frosting for the birthday cake blondies.
Buttercream Frosting
This quick buttercream frosting is super quick and easy just like these blondies! Start by adding the butter to a mixing bowl with the vanilla extract. Blend together until combined. Then add the powdered sugar. Use a hand mixer to blend everything together until a thick buttercream frosting forms. Dye the frosting pink with a few drops of dye.
Once the birthday cake blondies have cooled, spread the buttercream all over the top, spreading evenly. Last, but not least sprinkle the blondies with more confetti sprinkles. Place in the fridge and allow the buttercream to chill a bit. Cut the blondies into 9 even bars and enjoy!
