How to Make Lemon Crumb Bars
Step 1: Prepare the Crust
Preheat your oven to 350°F (175°C). In a large bowl, mix together the flour, sugar, baking powder, melted butter, and salt until crumbly. This mixture creates a buttery crust that holds everything together. Reserve 1/2 cup of this mixture for topping later. Press the remaining mixture firmly into the bottom of an 8×8-inch baking pan lined with parchment paper. Bake it for about 12-15 minutes until it turns lightly golden. This initial bake sets up a delicious base for your bars.
Step 2: Make the Lemon Filling
In another bowl, whisk together the eggs, sugar, flour, lemon juice, and lemon zest until smooth. This step is crucial because it combines all those bright flavors into a luscious filling that contrasts beautifully with the crumbly crust.
Step 3: Assemble the Bars
Once your crust is baked and slightly cooled, pour the lemon mixture evenly over it. Then sprinkle that reserved crumb mixture on top! This will create a lovely texture contrast between the creamy filling and the crunchy topping.
Step 4: Bake Again
Bake everything together for an additional 20-25 minutes or until the filling is set and the top is lightly golden. The aroma wafting through your kitchen during this time will be irresistible!
Step 5: Cool and Serve
Allow your bars to cool completely before placing them in the refrigerator for at least an hour. Chilling helps them firm up nicely. When you’re ready to serve, slice them into squares and dust with powdered sugar if desired—this adds such a lovely touch!
Now you have a refreshing dessert that’s sure to impress! Enjoy sharing these Lemon Crumb Bars with family and friends!
Pro Tips for Making Lemon Crumb Bars
Creating the perfect lemon crumb bars can be a delightful experience with just a few helpful tips.
- Use fresh ingredients: Fresh lemons and high-quality butter will enhance the flavor of your bars, making them more vibrant and delicious.
- Don’t skip the chilling step: Allowing the bars to chill in the refrigerator helps set the filling properly, ensuring a clean slice and a refreshing taste.
- Adjust sweetness to your taste: If you prefer a tangier flavor, feel free to reduce the sugar in the lemon filling slightly. This will balance out the sweetness of the crust.
- Check for doneness: To ensure your bars are perfectly baked, look for a lightly golden top and a filling that is set but still slightly jiggly in the center—this guarantees a moist texture.
- Experiment with flavors: Consider adding a pinch of ginger or vanilla extract to the crust for an extra layer of flavor.
