Strawberry Jam Bars: A Slice of Sunshine

Every summer, my grandmother’s kitchen transformed into a jam-making factory. Jars of vibrant, ruby-red strawberry jam lined the countertops, their sweet aroma filling the air. While she meticulously canned batch after batch, a simpler treat was often whipped up with the surplus: these delightful strawberry jam bars. The buttery, crumbly crust, the sweet-tart jam, and the crunchy cornflake topping—it was summer in a single bite, a taste that instantly transports me back to those sun-drenched days.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 30 minutes
• Total Time: 45 minutes
• Yields: 24 bars
• Dietary Type: Vegetarian

Ingredients

• ½ cup butter or margarine, softened
• ½ cup packed brown sugar
• 1 large egg
• 1 (18 ¼ ounce) package white cake mix or yellow cake mix
• 1 cup finely crushed corn flakes
• 1 ½ cups strawberry jam or strawberry preserves

Equipment Needed

• Mixing bowl
• Measuring cups and spoons
• 13 x 9 inch baking pan
• Grease for pan
• Wire rack

Instructions

1. Preheat your oven to 350°F (175°C). Ensure the oven rack is positioned in the center for even baking.
2. In a mixing bowl, cream together the softened butter or margarine and packed brown sugar until the mixture is light and smooth. Using an electric mixer will expedite this process, but it can also be done by hand with some extra elbow grease.
3. Add the egg to the creamed butter and sugar, and mix well until fully incorporated. The mixture should be consistent and homogenous.
4. Gradually add the dry cake mix and crushed corn flakes to the wet ingredients. Mix until just combined. Be careful not to overmix, as this can result in a tough crust.
5. Reserve 1 ½ cups of the dough mixture for the topping. This is crucial for the signature crumbly top of the bars. Set this portion aside.
6. Press the remaining dough evenly into a greased 13 x 9 inch baking pan. A lightly floured hand or the back of a spoon can help prevent the dough from sticking while pressing it down. Make sure the base is even in thickness for uniform baking.
7. Carefully spread the strawberry jam or strawberry preserves evenly over the crust. Avoid getting jam on the sides of the pan, as it can burn during baking.
8. Sprinkle the reserved dough evenly over the jam layer. Gently press down the sprinkled dough to help it adhere to the jam.
9. Bake at 350°F (175°C) for 30 minutes, or until the bars are golden brown. The edges should be slightly darker than the center, and the topping should be nicely browned. If the topping starts to brown too quickly, you can loosely tent the pan with aluminum foil for the last 10 minutes of baking.
10. Remove the pan from the oven and cool completely on a wire rack before cutting into bars. Cooling completely is essential, as the jam will firm up as it cools, making the bars easier to cut and handle.
11. Cut into bars of your desired size.

Expert Tips & Tricks

• For a richer flavor, use browned butter in the crust. Simply melt the butter in a saucepan over medium heat and cook until the milk solids turn brown and the butter smells nutty. Let it cool slightly before using.
• If your jam is too thick to spread easily, warm it gently in a saucepan over low heat or in the microwave in short bursts until it becomes more pliable.
• To prevent the corn flakes from becoming soggy, crush them just before adding them to the dough.
• For a more decorative touch, use a fork to create a pattern on the surface of the jam before adding the topping.
• For easier cutting, chill the bars in the refrigerator for about 30 minutes before slicing.
• Don’t have corn flakes? Try using crushed graham crackers, oats, or even chopped nuts for the topping.

Serving & Storage Suggestions

These strawberry jam bars are delicious served at room temperature. They are perfect as an afternoon snack, a sweet treat with coffee or tea, or as part of a dessert buffet.

To store, keep the bars in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. For longer storage, you can freeze the bars for up to 2 months. Wrap them individually in plastic wrap before placing them in a freezer-safe container to prevent freezer burn. Thaw overnight in the refrigerator before serving.

FAQs (Frequently Asked Questions)

Q: Can I use a different size pan?
A: While a 13 x 9 inch pan is recommended, you can use a different size pan. However, you may need to adjust the baking time accordingly. For a smaller pan, the bars will be thicker and may require a longer baking time.

Q: My crust is too crumbly. What did I do wrong?
A: This can happen if you overmixed the dough or if your butter was too soft. Be sure to mix the dough until just combined and use butter that is softened but not melted.

Q: Can I make these bars ahead of time?
A: Yes, these bars can be made ahead of time. They can be stored at room temperature for up to 3 days or in the refrigerator for up to a week.

Q: My jam is bubbling over during baking. What should I do?
A: This can happen if you used too much jam or if your oven is too hot. Reduce the amount of jam slightly and make sure your oven temperature is accurate.

Q: Can I use fresh strawberries instead of jam?
A: While it’s not a direct substitution, you can use fresh strawberries. You’ll need to macerate them with sugar and a little cornstarch to create a jam-like consistency before spreading them on the crust. This will require adjusting the amount of sugar and cornstarch depending on the sweetness and juiciness of the berries.
