How to Top Cake Mix Blondies
Cake mix blondies are one of the easiest desserts to make, but the right toppings can transform them from simple treats into eye-catching bakery-style bars. Whether you’re baking for birthdays, festive celebrations, bake sales, or gifting, adding colorful sprinkles is a quick and fun way to elevate your blondies.
Why Use Sprinkles on Blondies?
Unlike cakes that are covered with frosting, blondies have a chewy, buttery surface that pairs perfectly with decorative toppings. Sprinkles instantly add:
• Bright vibrant colors
• Crunchy texture
• Festive appearance
• Professional-looking presentation
• Endless customization for different occasions
Whether you’re making classic vanilla, Funfetti, chocolate chip, or caramel blondies, sprinkles are an effortless finishing touch.
Best Ways to Top Cake Mix Blondies
1. Sprinkle Before Baking
This method gives the sprinkles a slightly baked-in appearance.
How to do it:
• Pour blondie batter into the baking pan.
• Evenly scatter sprinkles over the surface.
• Bake as directed.
This works best with:
• Jimmies
• Confetti sprinkles
• Sugar crystals
Avoid using delicate metallic decorations that may lose their shine during baking.
2. Sprinkle After Baking
For the brightest colors and crispest finish, decorate after baking.
Simply:
• Let the blondies cool slightly.
• Spread a thin layer of buttercream, chocolate ganache, melted white chocolate, or royal icing.
• Add sprinkles before the topping sets.
This method creates vibrant, professional-looking blondies.
3. White Chocolate Drizzle + Sprinkles
One of the most popular bakery-style finishes.
Instructions:
1. Melt white chocolate.
2. Drizzle over cooled blondies.
3. Immediately add sprinkles.
4. Allow the chocolate to set before slicing.
The white chocolate acts as edible glue while adding extra sweetness.
4. Buttercream Decoration
If you’re serving blondies at parties, pipe small buttercream swirls on top.
Finish each swirl with:
• Sprinkle Mixes
• Pearls
• Confetti sprinkles
This turns simple blondies into elegant dessert bars.
Tips for Decorating Blondies
• Allow blondies to cool before decorating with chocolate or buttercream.
• Add sprinkles immediately after applying melted chocolate or icing so they stick properly.
• Avoid adding too many large sprinkles, as they can make slicing difficult.
• Use a sharp knife and wipe it clean between cuts for neat edges.
• Store decorated blondies in an airtight container.
How to Store Decorated Blondies
Proper storage helps keep your blondies fresh.
• Room temperature: Up to 4 days in an airtight container.
• Refrigerator: Up to 1 week.
• Freezer: Up to 3 months (freeze before decorating for the best results).
Keep decorated blondies away from direct sunlight and humidity to preserve the colors of the sprinkles.
FAQ
1. Can I bake sprinkles directly on top on blondies?
Yes. Jimmies, confetti sprinkles, and sugar sprinkles hold up well during baking. Decorative metallic or delicate sprinkles are better added after baking.
2. Do sprinkles melt in the oven?
Most sprinkles keep their shape, although some colors may soften slightly depending on the baking temperature and time.
3. What’s the best topping to help sprinkles stick?
Melted white chocolate, buttercream, chocolate ganache, royal icing, and cookie icing all work well as edible “glue”.
4. When should I add sprinkles to blondies?
You can add them either before baking or immediately after applying melted chocolate or frosting to cooled blondies.
5. Can I freeze decorated blondies?
Yes, but for the best appearance, it’s recommended to freeze plain blondies first and decorate them after thawing.
