Step-by-Step Instructions
Preheating and Preparation
- Preheat the oven to 350°F (175°C).
- Prepare the baking pan with parchment paper.
Start by lining a 9x13 inch pan with parchment. This helps with easy removal later. The overhang on the sides is key for lifting out the blondies.
Mixing Wet Ingredients
- Cream together butter and brown sugar.
- Add eggs and vanilla extract.
In a large bowl, mix the softened butter with brown sugar. Use an electric mixer to blend them until light and fluffy. This takes about 2-3 minutes. Next, add the eggs one at a time. Mix well after each addition. Pour in the vanilla extract and stir until smooth.
Combining Dry Ingredients
- Whisk together dry ingredients in a separate bowl.
- Gradually add dry mixture to wet mixture.
In another bowl, whisk the flour, baking powder, baking soda, sea salt, and yellow cake mix. Once well blended, add this dry mix to the wet mix. Stir gently until just combined. Be careful not to overmix, as this can change the texture.
Adding Final Touches
- Fold in sprinkles and white chocolate chips.
- Pour batter into prepared baking pan.
Use a spatula to fold in the colorful sprinkles and white chocolate chips. This adds fun and flavor! Pour the batter into the lined pan and spread it evenly. For extra fun, sprinkle some more colorful sprinkles on top.
Baking Process
- Bake for 20-25 minutes and check for doneness.
- Allow cooling and cut into squares.
Place the pan in the oven and bake for 20-25 minutes. To check if they are done, insert a toothpick in the center. It should come out clean or with a few moist crumbs. Once baked, let them cool in the pan for about 10 minutes. Use the parchment to lift them out. Transfer to a wire rack to cool completely. After cooling, cut into squares and enjoy!
Tips & Tricks
Perfecting the Texture
To get the best texture for your Funfetti cake batter blondies, avoid overmixing the batter. Overmixing makes them dense and tough. Mix just until you see no dry flour. Using room temperature ingredients helps too. When butter and eggs are warm, they mix better. This gives your blondies a soft, chewy texture.
Enhancing Flavor
For a fun twist, consider adding extracts or flavorings. Almond extract adds a nice touch. You can also use high-quality white chocolate chips. They melt beautifully and add a creamy sweetness. The better the chocolate, the richer the taste.
Presentation Suggestions
A great way to impress is to drizzle melted white chocolate on top. This makes your blondies look fancy and adds extra sweetness. Serve them on colorful plates for a pop of color. This simple step makes your dessert even more inviting and fun.
Pro Tips
- Use Room Temperature Ingredients: Ensure your eggs and butter are at room temperature for better emulsification, resulting in a smoother batter.
Variations
Flavor Variations
You can easily change the flavor of your blondies. Here are some fun ideas:
- Add nuts for crunch: Walnuts or pecans give a nice texture.
- Substitute chocolate cake mix for a chocolate version: This makes a rich, chocolaty treat.
Dietary Adjustments
Want to make these blondies fit your diet? Try these swaps:
- Gluten-free options using almond or coconut flour: This works well if you avoid gluten.
- Vegan substitutions for eggs and butter: Use flax eggs and coconut oil instead.
Festive Themes
Make your blondies special for any occasion:
- Use seasonal sprinkles: Choose holiday-themed sprinkles for festive flair.
- Customize for birthdays with colored frosting: Add bright frosting to delight anyone celebrating.
Storage Info
Best Storage Practices
To keep your blondies fresh, place them in an airtight container. This will help them stay moist and soft. You can store them at room temperature for about three days. If you want them to last longer, refrigerate them. Just remember, they might lose a bit of their softness in the fridge.
Freezing Tips
If you want to enjoy these blondies later, freezing is a great option. First, cut the blondies into squares. Wrap each piece in plastic wrap, then place them in a freezer bag. This helps prevent freezer burn. They'll be good for up to three months in the freezer.
When ready to eat, take them out and let them thaw at room temperature. You can also warm them up in the oven at 350°F (175°C) for about 10 minutes. This will bring back that fresh-baked taste. Enjoy your sweet treat!
