What Could Be More Perfect For July 4 And All Summer Long

I waited until I had a gaggle of people around to eat these American flag oven s'mores. It finally happened last night. An unwelcome downpour of rain at a birthday party made a campfire impossible. Oven s'mores to the rescue!

Even though I'm a little late to the party with this post, I think they'd be perfect all summer long, right up through the all-American Labor Day holiday weekend. Just the process of making them is fun and easy, and it definitely got the birthday party guests involved!

You need chocolate, marshmallows, colorful sanding sugar, a little butter or cooking spray, and a thirteen-by-nine-inch pan. Everything you need is at Walmart!

A disposable pan works fine, but I could not resist using my vintage blue Pyrex baking dish to frame the oven s'mores! (Papa Steve found mine at a garage sale!)

Why You'll Love Oven S'mores ❤❤❤

You'll love these oven s'mores because they're fun to make, and the sanding sugar gives the toasted marshmallows an over-the-top crunchy goodness!

You can make them in any weather, any time of day or night, and you can absolutely make them ahead and bake them later!

How To Make Festive "S'merican" S'mores

Lightly butter or spray a thirteen-by-nine-inch pan and lay unwrapped plain Hershey bars on the bottom of the pan. Now that I have made them once, next time, I will make a double layer of Hershey bars or put about a half-inch of chocolate chips in the bottom of the pan. How could more chocolate ever be wrong?

Make a workstation with plates, skewers, cups of water, and sanding sugars. We used all disposable dishes but that is optional. The water should be deep enough to dunk a marshmallow. I used a separate plate for each color of sugar.

Now, the fun begins! Use a skewer to spear a marshmallow and dip it in water. Next, roll it in colored sanding sugar so it's coated all around the outside. Place it on the chocolate bars in rows, using the photo as a guide.

We used more marshmallows than the original model we saw, filling the pan completely. When we were done, we used almost a full bag of large marshmallows.

Let the marshmallows dry for about fifteen minutes while you tidy up and preheat the oven to 450 degrees. Before we made the flag oven s'mores, I did not know how much the white sanding sugar would do to enhance the color and flavor of the white stripes, but it is an amazing touch; don't skip it!!

Pop the pan into the 450-degree oven for seven to ten minutes. The marshmallows will puff and brown and get all gooey and toasty, and the chocolate will melt. Your nose will tell you when they're almost done because that toasted marshmallow fragrance will fill the kitchen!

Break graham crackers into small rectangles to use as dippers. Enjoy this dip while it's warm and gooey. We kept going back for more bites and even put some on top of our homemade ice cream! We all agree that the added sparkle, crunch, and sweetness of the sanding sugar sent this right over the top!

I'm all inspired now, and I want to make more! I want to try making them in the microwave and try threading the sugared and dried marshmallows on a skewer and toasting them like usual over a fire. I'll report back soon!

This is one of those clever ideas that involves the guests so much and tastes so yummy, I hope to make it an annual tradition for the summer holidays!
