How to Make Super Easy Oreo Cake Bars

Preheat the oven to 350°F (175°C). Grease a 9 × 13-inch baking dish and line the bottom with parchment paper for easy removal later.

Crush the Oreo cookies into fine crumbs. You can use a food processor or a rolling pin to get them nice and fine. The filling adds extra creaminess to your cake!
-
Combine the flour, cocoa powder, sugar, baking powder, salt, and crushed Oreo cookies in a large bowl. Mix well to ensure the dry ingredients are evenly distributed.

What should I do if my cake bars turn out dry?
Very! If your bars end up dry, remember to check your oven’s temperature; it might run hot. Also, measure your ingredients accurately, as too much flour can lead to a dry texture. Next time, try underbaking slightly—aim for a toothpick with a few moist crumbs when testing for doneness.
