Ranking #1 in nearly every "favorite cookie" poll, the chocolate chip cookie is pretty much the go-to cookie of choice for both kids and grownups alike.

Cake mix and oats make the crust and topping that surrounds a sweet raspberry jam filling in these simple dessert bars.

1 package (15-18 ounce size) yellow cake mix
1 1/2 cup quick-cooking oats
3/4 cup melted butter
1 jar (12 ounce size) raspberry jam
1 tablespoon water
Preheat the oven to 375 degrees F.
Combine the cake mix and oats in a large bowl. Mix well. Stir in the melted butter, mixing until the cake mix and oats are crumbly.
Place approximately 3 cups of the cake mixture in a 9x13-inch baking dish. Pat the mixture firmly to form a crust.
Combine the jam and water in a bowl and whisk until combined. Spread the jam mixture evenly over the cake mix crust.
Sprinkle the remaining cake mix mixture evenly over the raspberry filling. Pat gently (the filling may not be completely covered).
Place the raspberry bars in the oven and bake at 375 degrees F for 25 minutes. Remove the pan from the oven and let the bars cool completely before cutting into squares. Store the bars in an airtight container at room temperature for up to 1 week or freeze for up to 3 months.
For an even layer of raspberry filling, drop dollops of the jam mixture over the crust and then gently spread it with the back of a spoon or an offset spatula.
If the topping isn't browning to your liking, you can broil the bars for a minute or two at the end of baking, watching closely to avoid burning.
Allowing the bars to cool completely before cutting will help you get cleaner slices.
For a more decadent treat, drizzle melted white chocolate over the cooled bars before cutting.
Try different cake mix flavors like white, lemon, or chocolate with different jams for a variety of tastes.
Yes, you can use any flavor of jam you prefer, such as strawberry, apricot, or blackberry, to change up the taste of your bars.
For a gluten-free version, use a gluten-free cake mix and ensure your oats are certified gluten-free.
Using fresh or frozen raspberries directly might result in a different texture and moisture content. For a similar effect, you could make a quick raspberry compote by cooking down the berries with a bit of sugar and then use that as your filling.
Chopped almonds, walnuts, or pecans can be mixed into the crumbly cake mix and oat mixture.
You can use old-fashioned oats instead; the texture will be slightly different but still delicious. Pulse them a few times in a food processor if you prefer a finer texture.
Since the sweetness primarily comes from the cake mix and jam, choose a cake mix with lower sugar content and a reduced-sugar jam to lower the overall sugar content.
Yes, you can substitute the melted butter with a neutral oil like vegetable or canola oil. The texture might change slightly but will still be tasty.
Large Mixing Bowl: For combining the cake mix and oats, and mixing in the melted butter to create a crumbly texture.
Measuring Cups and Spoons: For measuring the quick-cooking oats and water needed for the recipe.
Medium Bowl: For combining the jam and water for the fruit filling layer.
Whisk: For combining the raspberry jam and water in a bowl.
9x13-inch Baking Dish: For baking the raspberry bars in the oven.
Spatula: For spreading the jam mixture evenly over the crust and for patting down the remaining cake mixture on top.
Cooling Rack (optional): Can be used to cool the bars completely after baking, allowing for better air circulation.
Knife or Pizza Cutter: To cut the cooled raspberry bars into squares for serving.
Vanilla Ice Cream: Serve a scoop of vanilla ice cream alongside the raspberry bars to add creaminess and balance the tartness of the raspberries. The cool temperature and smooth texture contrast well with the chewy bars.
Lemon Glaze: Drizzle a lemon glaze over the finished bars for a zesty kick. The acidity of the lemon complements the sweetness of the jam.
Greek Yogurt: Pair the raspberry bars with a dollop of Greek yogurt for a refreshing touch. The tanginess of the yogurt offsets the sweetness of the bars.
Powdered Sugar Dusting: Lightly dust the raspberry bars with powdered sugar before serving. It adds visual appeal, while the sweetness of the sugar counters the tart raspberry flavor.
Mint Leaves: Garnish with fresh mint leaves for a pop of color and an aromatic element.
Chocolate Drizzle: A light drizzle of chocolate atop the bars adds a decadent layer. The richness of the chocolate pairs nicely with the fruity raspberry jam.
Chopped Nuts: Sprinkle toasted almonds or walnuts on top of the bars for added texture and flavor.
Cheese Plate: Offer the bars as part of a cheese plate, featuring soft cheeses like Brie or goat cheese. The creaminess of the cheese and the tartness of the raspberry jam create a nice contrast.

So easy and delicious! They no longer make 18 oz. boxed cake mixes; they're all now 15.25 oz. But the recipe still works. I love the versatility: you can substitute just about any flavor of jam or preserves. I made it with peach preserves. Will try it next with sour cherry preserves, white cake mix, and will add a half a teaspoon of almond extract to the cake mix-oat mixture. Slivered almonds might be good on it too.

These are very good, but 12oz of jam was too much. I used chocolate cake mix (couldn't find 18oz, they just had 15oz) and blackberry jam with chocolate chips on top. They fall apart easily but they're still delicious.

These bars are sooo good! I made them to the exact recipe the first time. The 2nd time I switched things up a bit. I use my own homemade raspberry jam and substitute 1 Tbsp of lemon juice for the water. I add a bit of milk to 1/2 the crumb mixture just for the bottom half, then for the top half I add 1/2 cup chopped pecans. My Tuesday night Trivia team raved. I'm going to try them next using my homemade cherry jam.

For a family reunion I made this recipe and the Almond Raspberry Diamond recipe. I like to compare. This one was the big favorite. It was so much easier to make too. The crust clung to the jam. Perfect crumblyness. The Almond recipe was more cake like and I thought the jam separated the layers too much. I used a homemade, low sugar raspberry freezer jam that had been in the freezer 2 years too long for both recipes and the raspberry flavor was still wonderful. Fast, easy and amazingly tasty. This is a new favorite. So quick and easy!
