Ingredients

For the Crumble / Base & Topping:

• 1 ½ – 2 Tassen Mehl (Allzweck)
• 1 Tasse brauner Zucker (light brown sugar), leicht gepackt
• ½ TL Backpulver
• 1 TL Salz
• 1 Tasse (ca. 225 g) kalte Butter, gewürfelt

• Saft von 3 Zitronen (ca. 6–8 EL; je nach Größe)
• Zitronenschale von 3 Zitronen

How to Make Lemon Oatmeal Crumble Bars

Step 1: Preheat the Oven

Preheat your oven to about 180 °C / 160 °C if using convection. Line a square baking dish (approximately 22–23 cm) with parchment paper for easy removal.

Step 2: Prepare the Crumble

In a large mixing bowl, combine:
1. Haferflocken
2. Mehl
3. Brauner Zucker
4. Backpulver
5. Salz

Add the cold butter cubes to the mixture and use your fingers or a pastry cutter to rub them together until you form a sandy texture with crumbles.

Step 3: Divide the Mixture

Take about half of the crumble mixture and press it firmly into the bottom of your prepared baking dish to form an even layer.

Step 4: Make the Filling

In another bowl, mix together:
1. Gezuckerte Kondensmilch
2. Zitronensaft
3. Zitronenschale

Stir until you have a smooth, creamy filling.

Step 5: Assemble Your Bars

Pour the lemon filling evenly over the oat base in your baking dish. Sprinkle the remaining crumble mixture on top of the filling.

Step 6: Bake

Place your assembled bars in the preheated oven and bake for about 25–30 minutes or until the crumble topping turns golden brown.

Step 7: Cool & Serve

Allow your Lemon Oatmeal Crumble Bars to cool completely before cutting them into squares. For an extra refreshing treat, serve chilled from the refrigerator!

How to Serve Lemon Oatmeal Crumble Bars

Lemon Oatmeal Crumble Bars are a delightful treat that can be enjoyed in various ways. Whether you’re serving them at a gathering or enjoying them on a quiet afternoon, these bars can be paired with different accompaniments to enhance their flavor.

With Fresh Berries

• Adding a mix of fresh berries like strawberries, blueberries, or raspberries can provide a refreshing contrast to the zesty lemon filling.

Drizzled with Honey

• A light drizzle of honey on top can add extra sweetness and create a lovely presentation on your dessert table.

Paired with Yogurt

• Serving these bars with a dollop of yogurt, whether plain or flavored, can give a creamy texture that balances the tartness of the lemon.

Accompanied by Whipped Cream

• Lightly sweetened whipped cream adds an airy touch that complements the dense texture of the crumble bars beautifully.

Enjoyed with Tea or Coffee

How to Perfect Lemon Oatmeal Crumble Bars

To achieve the best results when making Lemon Oatmeal Crumble Bars, consider these helpful tips:

• Use cold butter: Cold butter helps create a flaky and crumbly texture in both the base and topping, ensuring your bars are perfectly baked.
• Measure ingredients accurately: Accurate measurements are crucial for the right consistency. Use measuring cups and spoons for precision.
• Don’t overmix: When preparing the crumble mixture, mix just until combined. Overmixing can lead to dense bars instead of light and crumbly ones.
• Let them cool completely: Allowing the bars to cool completely before slicing ensures clean cuts and better presentation.

Best Side Dishes for Lemon Oatmeal Crumble Bars

When serving Lemon Oatmeal Crumble Bars, consider pairing them with these delectable side dishes for a complete experience:

1. Minted Fruit Salad – A light fruit salad tossed with fresh mint adds brightness and complements the lemon flavor beautifully.
2. Vanilla Ice Cream – The creaminess of vanilla ice cream provides a rich contrast against the tartness of the lemon filling.
3. Coconut Chia Pudding – A creamy coconut chia pudding offers a nutritious side that pairs well with the sweet and tangy bars.
4. Almond Biscotti – Crunchy almond biscotti makes for a delightful companion, adding texture and flavor variety.
5. Citrus Sorbet – A refreshing citrus sorbet enhances the lemon theme while providing a cool treat on warm days.
6. Herbed Cheese Spread – A spreadable herbed cheese adds savory notes that balance out the sweetness of the bars beautifully.

Common Mistakes to Avoid

When making Lemon Oatmeal Crumble Bars, small mistakes can lead to big disappointments. Here are some common pitfalls to watch out for:

• Incorrect Measurements: Using too much or too little of any ingredient can affect texture and flavor. Always measure carefully using proper measuring tools.
• Not Chilling the Butter: If the butter is not cold enough, the crumble won’t achieve the desired texture. Make sure to use chilled butter for a crumbly topping.
• Overmixing the Filling: Mixing the filling too vigorously can introduce air and create a less creamy texture. Stir gently until just combined for a smooth consistency.
• Skipping the Cooling Time: Cutting into the bars before they cool can cause them to fall apart. Allow them to cool completely before slicing for clean edges.
• Using Different Citrus Fruits: Substituting lemons with other fruits can drastically change the flavor profile of your bars. Stick with lemons for that signature taste.
