This easy Independence Day treat is the kind of back-pocket dessert recipe that earns a permanent place in summer cooking. Using dry muffin mix powder as the base keeps the ingredient list short and the prep especially simple, while still baking into a soft, crowd-friendly bar that is ideal for cookouts, fireworks parties, and last-minute holiday gatherings. A few pantry staples turn an everyday baking mix into something festive, colorful, and surprisingly satisfying.
Serve these bars slightly warm or fully cooled with fresh strawberries, blueberries, and a dollop of whipped topping for a red, white, and blue presentation. They also pair nicely with vanilla ice cream, lemonade, iced tea, or coffee if you are setting out a dessert table for a holiday picnic or backyard meal.
4-Ingredient Oven Baked Independence Day Treat
Servings: 12
Ingredients
1 box dry unbaked muffin mix powder, about 13 to 16 ounces
2 large eggs
1/2 cup melted butter
1/3 cup red, white, and blue sprinkles
Directions
1. Preheat the oven to 350°F and lightly grease an oven-safe casserole dish, about 8x8 inches or similar in size.
2. Pour the dry muffin mix powder into the prepared casserole dish or into a mixing bowl if you prefer stirring before transferring.
3. Add the eggs and melted butter, then stir until a thick batter forms. Fold in most of the sprinkles, reserving a small amount for the top.
4. Spread the batter evenly in the dish and scatter the reserved sprinkles over the surface for a festive finish.
5. Bake for 22 to 28 minutes, or until the top is set and lightly golden and a toothpick inserted in the center comes out with just a few moist crumbs.
6. Let the treat cool for at least 15 minutes before cutting into squares and serving.
Variations & Tips
Berry Topping: For a fresher holiday look, spoon chopped strawberries and blueberries over the cooled bars just before serving. This adds color and a little tartness that balances the sweetness.
Mix Choice: Blueberry, corn muffin, and vanilla-style muffin mixes all work well here. If your muffin mix is already quite sweet, keep the sprinkles moderate so the final bars do not become overly sugary.
Pan Size Tip: An 8x8-inch dish will give you thicker bars, while a slightly larger dish will produce a thinner, more cookie-bar style treat. Start checking early if using a larger pan, since baking time may be shorter.
Texture Upgrade: If you want a softer, richer result, do not overbake. Pull the dish from the oven as soon as the center is set; residual heat will finish the job as it rests.
Make-Ahead Tip: These bars hold well for a day or two in an airtight container, making them practical for party prep. Add any whipped topping or fresh fruit right before serving so everything stays neat and bright.
