Ingredients

For the Streusel Base and Topping:

• 1 1/4 cups quick oats, uncooked
• 1 1/4 cups all-purpose flour
• 1/2 cup firmly packed brown sugar
• 1 teaspoon baking powder
• 1/4 teaspoon salt
• 7/8 cup margarine, melted

For the Filling:

• 1 cup raspberry jam or raspberry preserves
• 1/2 cup white chocolate chips (divided)
• 1/4 cup toasted chopped almonds

Equipment Needed

A few essential kitchen tools will make preparing these bars a breeze:

• An 8-inch square baking pan
• A large mixing bowl
• A medium mixing bowl
• A measuring cup set
• A measuring spoon set
• A spatula or spoon for stirring
• A wire cooling rack
• An oven

Instructions

Crafting these Raspberry Streusel Bars is a delightful process, starting with the crumble that forms both the base and the topping.

1. Begin by preheating your oven to 350°F (175°C). This ensures the oven is at the optimal temperature for even baking from the moment the pan goes in.
2. In a large mixing bowl, combine the quick oats, all-purpose flour, firmly packed brown sugar, baking powder, and salt. Whisk these dry ingredients together thoroughly to ensure the leavening and seasoning are evenly distributed.
3. Add the melted margarine to the dry ingredients in the large bowl. Stir with a spatula or spoon until the mixture comes together and resembles coarse crumbs. You want it to be well combined but still crumbly.
4. Reserve 1 cup of this crumb mixture aside. This will be used for the topping.
5. Take the remaining crumb mixture and press it firmly onto the bottom of an 8-inch square pan to form the base. Ensure it’s pressed down evenly to create a solid foundation for the filling.
6. Bake this crust in the preheated oven for 10 minutes. This initial bake helps to set the crust and prevent it from becoming soggy.
7. While the crust is baking, prepare the filling. Once the crust has had its initial bake, carefully remove the pan from the oven.
8. Spread the raspberry jam or preserves evenly over the baked crust. Be sure to spread it all the way to within about 1/4 inch of the edges to prevent it from bubbling over during the final bake.
9. Next, sprinkle 1/2 cup of the white chocolate chips evenly over the raspberry layer. These will melt into a sweet, creamy component of the filling.
10. Now, turn your attention to the reserved 1 cup of crumb mixture. In the medium mixing bowl, combine this reserved crumb mixture with the remaining 1/4 cup white chocolate chips and the toasted chopped almonds. Gently toss these together with a spoon or fork.
11. Sprinkle this almond and white chocolate chip streusel mixture evenly over the raspberry layer. Press down lightly into the fruit layer to help it adhere and create a cohesive topping.
12. Return the pan to the preheated oven and bake for 30 to 35 minutes, or until the streusel topping is golden brown and the jam is bubbly around the edges. The aroma filling your kitchen at this stage will be heavenly!
13. Once baked to perfection, carefully remove the pan from the oven and place it on a wire cooling rack. It is crucial to cool completely on the wire rack before cutting. This allows the bars to set properly, making them easier to slice and preventing them from falling apart.
14. After the bars have cooled entirely, cut into squares. Serve and enjoy the delightful blend of textures and flavors.

Expert Tips & Tricks

To elevate these already delightful bars, consider these professional insights:

• Jam Consistency: For the neatest filling, use a jam or preserves that is not overly runny. If your jam is quite loose, you can simmer it gently in a small saucepan for a few minutes to thicken it slightly before spreading.
• Toasting Almonds: To get the most flavor from your almonds, toast them gently in a dry skillet over medium-low heat until fragrant, or spread them on a baking sheet and toast in the oven for a few minutes at 350°F. Watch them closely, as they can burn quickly.
• Even Streusel Distribution: When pressing the base, aim for a uniform thickness. This ensures even baking and a delightful crust. For the topping, gently press it down so it adheres to the jam but doesn’t completely seal it, allowing for some bubbling.
• Cooling is Key: Resist the urge to cut into these bars while they’re warm. The cooling process is vital for achieving clean cuts and a pleasant texture. Allowing them to cool completely at room temperature will yield the best results.

Serving & Storage Suggestions

These Raspberry Streusel Bars are wonderfully versatile. Serve them as a delightful afternoon treat with a cup of tea or coffee, or as a simple yet elegant dessert after dinner. They are also a fantastic addition to a brunch spread.

For storage, these bars will keep well at room temperature in an airtight container for up to 2 days. If the weather is warm or humid, or if you have any remaining after 2 days, it’s best to store them in the refrigerator. They will maintain their quality in the fridge for up to a week. To enjoy a chilled bar, you can serve it directly from the refrigerator. If you prefer them at room temperature, allow them to sit out for about 20-30 minutes before serving. These bars also freeze beautifully; wrap them tightly in plastic wrap and then in aluminum foil, and they can be frozen for up to 2 months. Thaw overnight in the refrigerator.

Variations & Substitutions

While the classic combination of raspberry and white chocolate is divine, feel free to experiment!

• Other Berries: Replace the raspberry jam with strawberry, blackberry, or mixed berry jam for a different fruity twist.
• Chocolate Swap: If white chocolate isn’t your favorite, consider using milk chocolate chips or even dark chocolate chips. A mix of two types of chocolate can also be delicious.
• Nut Alternatives: If you have an almond allergy or simply prefer something else, toasted chopped pecans or walnuts would make excellent substitutes for the almonds. You could also omit the nuts entirely.
• Oat Varieties: While quick oats work wonderfully for a tender base, you could experiment with using rolled oats (old-fashioned oats) for a chewier texture. You might need to process them briefly in a food processor to break them down slightly.

FAQs

Q: Can I use fresh raspberries instead of jam?
A: While fresh raspberries are lovely, they contain more moisture. If you choose to use fresh berries, toss about 2 cups of fresh raspberries with 2 tablespoons of cornstarch and 2 tablespoons of sugar before spreading them on the crust. This will help thicken the juices.

Q: My streusel mixture seems too dry or too wet. What should I do?
A: If the mixture seems too dry and crumbly, add a teaspoon of melted margarine at a time until it holds together slightly when squeezed. If it appears too wet and paste-like, add a tablespoon of flour at a time until it reaches a crumbly consistency.

Q: How can I make sure the bars cut cleanly?
A: Allowing the bars to cool completely is the most important step for clean cuts. Once cooled, use a sharp knife and wipe it clean between cuts for the neatest slices.

Q: Can I make these bars gluten-free?
A: To make these bars gluten-free, you would need to substitute the all-purpose flour with a gluten-free all-purpose flour blend. Ensure your oats are also certified gluten-free. The texture might vary slightly depending on the gluten-free flour blend used.

Q: What kind of margarine is best for this recipe?
A: A good quality stick margarine that you melt yourself will work best. Tub margarines can sometimes contain more water, which can affect the texture of the streusel.
