Why You’ll Love It
So much flavor: While brownies are flavored with cocoa, blondies are flavored with vanilla and brown sugar, for a lighter flavor. These also have almond flavoring for max flavor!
Party-perfect: The rainbow sprinkles make these blondies look super-festive and ideal for any kind of party. Everyone’s going to want one.
Simple to whip up: There isn’t much more to do here than combine the batter ingredients, add Oreo chunks and sprinkles on top and bake the blondies in the oven.
Minimal prep time: It only takes about ten minutes to make the batter and get the blondies ready to go in the oven. If you’re making lots of other birthday foods at the same time, that’s good to know!
Birthday Cake Blondie Ingredients
A complete list of ingredients and amounts can be found in the recipe card below.
Golden Oreos: Although these have the same cream filling as regular Oreos, they are flavored with vanilla instead of chocolate.
Vanilla and almond extract: To add flavor to the blondies.
Brown sugar: When paired with the vanilla flavor, you end up with a mouthwatering caramel-like result.
White sugar: For sweetness.
Unsalted butter: Unsalted butter adds a lovely buttery flavor to these blondie cookie bars.
Rainbow sprinkles: To add that party-perfect flair!
Eggs: You need a whole egg plus an egg yolk for the batter.
Butter: Melt it first. Melted butter mixes in easily.
Salt: Just a pinch, to offset the sweetness and make it pop.

Make the blondie batter: Pulse Oreos in the food processor and then combine with the flour, baking powder, cornstarch, and salt. In another large bowl, beat the brown sugar and white sugar with the butter, then mix in the whole egg and egg yolk. Add almond and vanilla extract and mix. Now combine the wet ingredients with the flour mixture and mix until evenly incorporated.
Prepare the blondies for baking: Pour the batter into a parchment paper lined baking pan and smooth it level on top. Add Oreo chunks and colorful sprinkles on top, pressing them in a little.
Bake the blondies and serve: Bake the blondies until done, then cool slightly before slicing and serving.
Substitutions and Variations
Gluten-free option: If you want a gluten-free version, use gluten-free Golden Oreos (find them here) instead of regular ones and gluten-free flour instead of all purpose flour.
Golden Oreos: Swap Golden Oreos with classic chocolate or lemon Oreos.
Include some add-ins: Mix in white chocolate chips, butterscotch chips, chopped walnuts, or chopped pecans.
Add frosting on top: Spread a layer of cream cheese frosting or vanilla frosting over the cooled blondies. If you do this, add the sprinkles on top of the frosting instead of before baking the blondies.
Serving Suggestions
Appetizers: Begin your birthday party feast with roasted party nuts and any of these birthday party appetizers.
Party snacks: Fun dishes to serve up include Cajun shrimp deviled eggs, chips and party dips, and air fryer sweet potato tots.
Desserts: Finish with these birthday cake blondies and a glass of champagne or you could bring out the jello shots!
How to Store Birthday Cake Blondies
Store: Oreo birthday blondies can be stored in an airtight container on the counter for up to 3 days or in the refrigerator for up to 5 days.
Freeze: Wrap each blondie in plastic wrap, put them in a freezer-safe bag and freeze for up to 3 months.
Thaw: Thaw at room temperature before serving.
Top Tips
Making Oreo crumbs: Pulse the Oreos in a food processor until crumbly but not too fine. You can also put the cookies in a gallon-size Ziploc bag and break them apart with a mallet or rolling pin.
No over-mixing: Don’t overmix when you add the dry ingredients to the wet ingredients, otherwise you might end up with dense blondies.
Check for doneness: When the edges are golden brown, check whether a toothpick inserted into the center comes out clean. If so, your blondies are done.
Birthday Oreo Blondies FAQs
I like to add a scoop of vanilla ice cream and some fudge, caramel or chocolate sauce (for a sweet treat with all the birthday feels!) You might like to add some chopped fresh fruit as well.
No, you can just use an electric mixer and a mixing bowl.
