Funfetti Oreo Bars Ingredients
- 1 cup (226 g) butter, melted
- 1 ¼ cup (250 g) sugar
- ½ cup (100 g) light brown sugar, tightly packed
- 2 eggs + 1 egg yolk (room temperature preferred)
- 2 teaspoons vanilla extract
- 2 ½ cups (285 g) all-purpose flour
- 2 teaspoons cornstarch
- ½ teaspoon baking powder
- 1 teaspoon salt
- ½ cup (85 g) mini semisweet chocolate chips
- 16 + 5 Oreo cookies
- ¼ cup colored sprinkles
How to Make Funfetti Oreo Bars
- Preheat your oven to 350°F (177°C) and prepare a 9×9 inch pan by lining it with parchment paper or lightly greasing and flouring it.
- In a large bowl, combine the melted butter, sugar, and light brown sugar. Stir until well mixed.
- Add the eggs and egg yolk one at a time, stirring well after each addition. Then, stir in the vanilla extract.
- In a separate medium-sized bowl, whisk together the flour, cornstarch, baking powder, and salt.
- Gradually mix the dry ingredients into the wet ingredients until fully combined. Stir in the chocolate chips and colored sprinkles.
- Spread half of the batter evenly into the prepared pan. Press 16 Oreo cookies into an even layer over the batter.
- Drop the remaining batter by spoonfuls over the Oreo layer and use a spatula or knife to spread it evenly.
- Gently break the remaining 5 Oreos into pieces and press them into the top of the batter, if desired.
- Bake for 35-40 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean or with a few moist crumbs.
- Allow to cool before cutting into bars. Serve slightly warm for the best experience!
How to Serve Funfetti Oreo Bars for Maximum Wow Factor
These bars are perfect on their own, but for an extra special treat, serve them warm with a scoop of vanilla ice cream or a dollop of whipped cream. Pro tip: Drizzle with melted chocolate or caramel sauce for a decadent dessert that’ll impress any crowd!
Storing and Reheating Tips for Freshness
Store leftover bars in an airtight container at room temperature for up to 3 days or in the fridge for up to a week. To reheat, pop them in the microwave for 10-15 seconds for that just-baked warmth. For longer storage, wrap individual bars tightly and freeze for up to 2 months.
Fun Variations to Mix It Up
Swap out the mini chocolate chips for white chocolate or butterscotch chips for a different flavor twist. You can also use different cookie varieties like Golden Oreos or even peanut butter-filled ones. Feeling adventurous? Add a layer of Nutella or peanut butter between the Oreos and batter for an extra indulgent treat!
Time-Saving Hacks for Busy Bakers
To save time, melt the butter in the microwave instead of on the stove. Use pre-measured dry ingredients or a kitchen scale for quicker prep. If you’re in a rush, skip breaking the Oreos on top—they’ll still taste amazing!
Essential Equipment for Perfect Bars
A 9×9 baking pan is key for this recipe, and lining it with parchment paper makes cleanup a breeze. Use a sturdy spatula to spread the batter evenly, and a toothpick or cake tester to check for doneness. For extra precision, a kitchen scale ensures accurate measurements.
