Preparation Phase & Tools to Use

Equipping yourself with the right tools makes all the difference in the kitchen. To whip up these delightful blondies, you’ll want to gather a few essential items:

8×8 Square Baking Pan: A must for ensuring that your blondies cook evenly, creating that perfect chewy middle and golden edges.
Parchment Paper: Lining your pan with parchment not only prevents sticking but also makes lifting out your blondies a breeze once they cool.
Mixing Bowls: Having a good set of mixing bowls is vital for combining your ingredients seamlessly, especially when dealing with thick batters.
Wooden Spoon or Rubber Spatula: Your best friends for mixing! These tools enable you to fold ingredients together without overworking the dough, preserving that wonderful chewy texture.

Before you dive in, here’s a simple tip: ensure your ingredients are at room temperature. This little step will help create a smoother batter that bakes to perfection.

Ingredients for Funfetti Cake Batter Blondies

1 box (15.25 oz) Pillsbury Funfetti Cake Mix: This pre-mixed delight serves as the foundation of the blondies, bringing sweetness and flavor.
1/3 cup Wesson Vegetable Oil: The oil adds moisture and ensures the blondies remain soft and chewy.
2 large Eggland’s Best Eggs: Eggs bind the ingredients together, adding richness and a slight lift.
1/3 cup whole milk: This brings creaminess to the batter, enhancing the flavor and texture.
1/2 cup Betty Crocker Rainbow Sprinkles (extra, for topping): These colorful gems sprinkle joy on top, making each blondie a visual treat as well as a tasty one.

For those looking to put their own spin on this recipe, consider substituting the cake mix with gluten-free varieties or replacing vegetable oil with melted coconut oil for a tropical twist.

How to Make Funfetti Cake Batter Blondies

Preheat your oven to 350°F (175°C). Line an 8×8 square baking pan with parchment paper and give it a light grease with non-stick spray for easy removal.
In a large mixing bowl, combine the entire box of Pillsbury Funfetti Cake Mix, Wesson Vegetable Oil, the two large Eggland’s Best Eggs, and whole milk. Stir with a wooden spoon until a thick, sticky batter forms. Enjoy the scent of sweet vanilla as you mix.
Spread the sticky batter into the prepared baking pan, ensuring even coverage. Generously sprinkle the top with the extra Betty Crocker Rainbow Sprinkles—these add a delightful crunch once baked!
Bake in the preheated oven for 25-30 minutes. Look for the edges to turn golden brown and the center to set—this should mean your blondies are ready! Allow them to cool completely in the pan. Once cooled, lift them out using the parchment paper and slice into adorable squares.

Chef’s Notes & Helpful Tips

Make-Ahead Tips: You can prepare the batter a day in advance and store it in the refrigerator. Just give it a gentle stir before cooking!

Common Mistakes to Avoid

Overmixing the Batter: This can lead to tough blondies. Mix just until the ingredients are combined for that perfect chewy texture.

Incorrect Baking Times: Ovens often vary in temperature. Keep an eye on them near the end of the baking time to prevent drying out.
