Rainbow Chip fans, listen up! These blondies—stacked with sugar cookie dough, birthday cake sandwich cookies and Rainbow Chip cake batter, all drizzled with your favorite Rainbow Chip frosting—are the next thing you need to bake. ASAP. Yeah, they’re as amazing as they sound!
One of the best things about these bars is they are way simpler to make than they look. The main ingredient list is short: Betty Crocker sugar cookie mix, Betty Crocker Super Moist™ Party Rainbow Chip cake mix, Oreo™ birthday cake flavor creme sandwich cookies and Rainbow Chip frosting. (For the complete list of ingredients and measurements, check out the full recipe below.)
First, preheat your oven to 350°F and grease a 13x9-inch pan and line it with parchment paper. Next, prepare the cookie dough as directed on the pouch. Break the dough into pieces and scatter across the bottom of the prepared pan, and then, using your hands or an offset spatula, press the dough into a thin, even layer.
Next up is the Oreo cookie layer. You’ll need 24 cookies for this recipe, which makes 24 bars. This means every square gets its own little surprise inside! Place the cookies on top of the sugar cookie layer in even rows.
For the final layer, make the Rainbow Chip cake batter by beating the cake mix, water, melted butter and eggs together. This batter is thicker than cake batter typically is in order to achieve the density of blondies. Spread the batter evenly in the pan so it completely covers both cookie layers.
Bake for about 30 minutes, or until a toothpick inserted in the center comes out clean. Allow the bars to cool completely. All that’s left after that is to drizzle with Rainbow Chip frosting! Simply microwave some frosting in a bowl for a few seconds until it’s thin enough to drizzle over the bars.
