Ingredients

For the Oatmeal Crust and Topping:

1 cup margarine
2 cups packed light brown sugar
2 eggs
1 teaspoon vanilla extract
1 teaspoon powdered instant coffee
3 cups quick-cooking oats
2 1/2 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt

For the Chocolate Filling:

1/2 cup margarine
2/3 cup cocoa
1/2 cup sugar
1 (14 ounce) can sweetened condensed milk
1 1/2 teaspoons vanilla

Equipment Needed

Large mixing bowl
Electric mixer
Measuring cups and spoons
Jelly roll pan (approximately 10×15 inches)
Medium saucepan
Wooden spoon or spatula

Instructions

Preheat your oven to 350 degrees F (175 degrees C). Generously grease and flour a jelly roll pan (approximately 10×15 inches). This ensures the bars release easily after baking.
In a large mixing bowl, cream together 1 cup of margarine and 2 cups of packed light brown sugar using an electric mixer until the mixture is light and fluffy. This step is crucial for creating a tender and delicious crust.
Add 2 eggs, 1 teaspoon of vanilla extract, and 1 teaspoon of powdered instant coffee to the creamed mixture. Mix until well combined. The coffee enhances the chocolate flavor beautifully, even though it’s subtle.
In a separate bowl, combine 3 cups of quick-cooking oats, 2 1/2 cups of all-purpose flour, 1 teaspoon of baking soda, and 1/2 teaspoon of salt. Whisk together to ensure even distribution of the dry ingredients.
Gradually add the dry ingredients to the creamed mixture, mixing on low speed until just combined. The batter will be quite stiff.
If necessary, stir in the last part of the dry ingredients by hand to avoid overmixing. Overmixing can lead to a tough crust.
Reserve approximately 2 cups of the dough mixture. This will be used as the topping.
Press the remaining dough evenly over the bottom of the prepared jelly roll pan. Use your fingers or the back of a spoon to ensure a consistent layer.
Now, prepare the chocolate filling. In a medium saucepan, melt 1/2 cup of margarine over low heat.
Stir in 2/3 cup of cocoa and 1/2 cup of sugar. Mix until well combined.
Add 1 (14 ounce) can of sweetened condensed milk to the saucepan.
Cook, stirring constantly, until the filling is smooth and thick. This usually takes a few minutes. Be patient and keep stirring to prevent scorching.
Remove the saucepan from the heat and stir in 1 1/2 teaspoons of vanilla.
Spread the chocolate filling evenly over the oatmeal mixture in the pan.
Sprinkle the reserved oatmeal mixture over the chocolate filling. Crumble it with your fingers for an even distribution.
Bake for 25 minutes, or until the top is golden brown. Keep an eye on the bars towards the end of the baking time to prevent burning. The chocolate filling will remain soft.
Let cool completely before cutting into bars. The filling will set up more as it cools.

Expert Tips & Tricks

For an extra layer of flavor, add a pinch of sea salt to the chocolate filling. It enhances the sweetness and creates a wonderful contrast.
If your dough is too sticky to press into the pan, lightly flour your fingers or the back of a spoon.
Don’t overbake the bars! The chocolate filling should be soft, not dry.
For a richer chocolate flavor, use dark cocoa powder.
To make cutting easier, chill the bars in the refrigerator for about 30 minutes before slicing.
If you don’t have a jelly roll pan, you can use a 9×13 inch baking pan, but the bars will be thicker and require a longer baking time. Check for doneness after 30 minutes.

Serving & Storage Suggestions

These Chocolate Filled Oatmeal Bars are delicious served warm with a scoop of vanilla ice cream or a dollop of whipped cream. They’re also great enjoyed at room temperature with a glass of milk or a cup of coffee.

Store leftover bars in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week. You can also freeze the bars for up to 2 months. Thaw them in the refrigerator overnight before serving. To reheat, warm individual bars in the microwave for a few seconds or in a preheated oven at 350 degrees F (175 degrees C) for a few minutes.

Variations & Substitutions

Gluten-Free: Use a gluten-free all-purpose flour blend in place of the regular all-purpose flour. Be sure to choose a blend that contains xanthan gum for the best texture.
Dairy-Free: Substitute the margarine with a dairy-free butter alternative. Ensure the butter alternative is suitable for baking.
Nut-Free: This recipe is naturally nut-free, but always double-check the labels of your ingredients to ensure they are processed in a nut-free facility, especially if you have severe allergies.
Spice it up: Add a teaspoon of cinnamon or a pinch of cayenne pepper to the oatmeal mixture for a warm, spicy twist.
Add Nuts: Add 1/2 cup of chopped walnuts or pecans to the oatmeal mixture for a crunchy texture.
Chocolate Chips: Sprinkle chocolate chips on top of the chocolate filling before adding the oatmeal topping for extra chocolate goodness.

FAQs (Frequently Asked Questions)

Q: Can I use regular rolled oats instead of quick-cooking oats?

A: While you can, the texture will be slightly different. Quick-cooking oats are finer and will create a more cohesive crust. If using rolled oats, pulse them in a food processor a few times to break them down slightly.

Q: My chocolate filling is too thick. What should I do?

A: Add a tablespoon or two of milk (dairy or non-dairy) to thin it out slightly. Stir until smooth.

Q: Can I make these bars ahead of time?

A: Absolutely! They’re a great make-ahead dessert. Bake them as directed and store them in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.

Q: My topping is browning too quickly. What can I do?

A: Tent the pan with aluminum foil to prevent further browning.

Q: Can I use a different kind of chocolate?

A: You can experiment with using melted chocolate chips in the filling instead of cocoa powder. Semi-sweet or dark chocolate would both work well. Be sure to adjust the amount of sugar accordingly.
