Key ingredients for sheet pan funfetti cookie bars
- 1 cup butter (softened to room temperature)
- 1 ½ cups brown sugar
- 2 large eggs
- 1 Tablespoon vanilla
- 2 teaspoons baking powder
- 1 teaspoon salt
- 3 cups flour
- 2 cups white chocolate chips
- 1 cup sprinkles
Ingredient notes & swaps
- Butter: Softened butter is crucial for the right consistency; if you’re in a pinch, you can use margarine, but the flavor will differ slightly.
- Flour: All-purpose flour gives the bars structure. Avoid using whole wheat for a denser texture; cake flour can yield a fluffier cookie.
- Sugar: Brown sugar adds moisture and a slight caramel flavor, but you can use granulated sugar in half the amount as a substitute, adjusting for the loss of moisture.
Step-by-step instructions
To make these delicious sheet pan funfetti cookie bars, follow these easy steps for a delectable treat:
- Preheat the oven to 350℉.
- In a large mixing bowl, cream together the softened butter and brown sugar until light and fluffy.
- Mix in the eggs and vanilla until well combined.
- Add the baking powder, salt, and flour and mix until no streaks remain.
- Fold in the white chocolate chips and sprinkles, reserving some for topping.
- Spray a half baking sheet (18 x 13 inch) with nonstick cooking spray, then spread the dough out evenly in the pan.
- Top with the reserved sprinkles for a colorful finish.
- Bake for 20-25 minutes, or until the center is set and the edges are golden brown.
- Let cool completely before cutting into squares.
Pro Tip: Let the bars cool completely before slicing for cleaner edges and to help them hold their shape.
Visual cues to look for include a largely set center and edges that have turned a beautiful golden brown, making the aromas wafting from the oven hard to resist.
Helpful cooking tips
- Ensure your butter is at room temperature for smooth blending.
- For added texture, consider adding chopped nuts or crushed cookies to the mix.
- If you prefer a more cake-like texture, slightly increase the flour by a quarter cup.
- For a fun twist, use different types of chocolate chips or even a mix of colors in your sprinkles.
Serving suggestions
These cookie bars are perfect as-is for a satisfying snack, but they really shine with a few extra touches. Consider serving them warm, topped with a scoop of vanilla ice cream or a drizzle of melted chocolate for a decadent dessert. For parties, placing the bars on a colorful platter can brighten up any table, and they pair wonderfully with a glass of milk or a cup of coffee.
How to store & freeze
Store any leftover cookie bars in an airtight container at room temperature for up to a week. If you’d like to keep them longer, try freezing them! Simply wrap each square tightly in plastic wrap and place them in a labeled freezer bag. They can be frozen for up to three months; just allow them to thaw at room temperature before serving.
How to fix common issues
If your cookie bars turn out dry, it may be due to too much flour or overbaking. Be sure to measure flour accurately and keep a close eye on the baking time. To remedy any potential sogginess, if you notice the batter has not set after the recommended time, let it bake a few more minutes while watching carefully to prevent burning.
Recipe variations
If you’re feeling adventurous, here are a few fun variations to try with your sheet pan funfetti cookie bars:
- Swap in different types of chocolate, such as dark or milk chocolate chips.
- For a fruity flavor, fold in mini marshmallows or dried fruit.
- To enhance the vanilla flavor, you can substitute half of the butter for flavored extracts like almond or coconut.
Common questions
Can I use salted butter instead of unsalted?
Yes, you can use salted butter, but be cautious with the added salt in the recipe. You might want to reduce the salt to half a teaspoon to balance the flavors.
How do I know when the cookie bars are done?
The edges should be golden brown, and when you gently press the center, it should feel set with a slight bounce back. The aroma will be delightful and indicate they are ready.
Can these cookie bars be made dairy-free?
Yes, substitute the butter with a dairy-free margarine or coconut oil, and use dairy-free chocolate chips, ensuring all other ingredients used are dairy-free.
Can I double the recipe?
Absolutely! Just use two sheet pans to bake simultaneously or bake in batches, but monitor the baking time, as it might vary slightly when doubling the ingredients.
How long do these cookie bars last?
When stored properly in an airtight container, they can last at room temperature for up to one week and in the freezer for three months.
Sheet pan funfetti cookie bars are an incredible way to celebrate any occasion with minimal effort and maximum joy. They’ll quickly become a staple in your baking repertoire, ensuring every gathering is sweetly memorable!
