The recipe makes the most of a handy packaged brownie mix, so they're fast to fix. If you don't have the mini M&Ms, use chocolate chips instead. Our kids love these rich fudgy squares with a scoop of ice cream.—Jennifer Trenhaile, Emerson, Nebraska

"This is a big hit at our local volunteer fire department! After the first batch, it was immediately requested again. Now, I make two batches. However, I make two trays of brownies and only use one batch of oat topping and sprinkle over the top of the two trays. Elimating the bottom layer. quick, easy and upgrades brownies to a new level of crunch. It is a winner!"

"I liked the ease of the recipe by using a boxed brownie mix. Next time I think I will try putting all the oat mixture on the bottom- as I would have liked that layer thicker."

"Delicious and easy! I used dark chocolate M&M's and did not add nuts as these were for a church dinner. Will make them again."

"I made this recipe, but shortened steps. I made the brownie recipe and put all the the oatmeal, nut, brown sugar mixture all on the top. I didn't have the M - Ms. They still turned out delicious. I will probably make them that way again. I'm all for easy.
