- 1.5 cups all-purpose flour: The essential building block for creating the crust and topping.
- ½ teaspoon baking soda: Helps the crust rise slightly for a fluffy texture.
- ¼ teaspoon salt: Enhances and balances the sweetness of the bars.
- 1 cup sour cream or Greek yogurt: Provides creaminess and tang to the filling.
- ¾ cup granulated sugar: Sweetens the filling perfectly, creating a delightful contrast with the lemon.

Recipe Steps for Creamy Lemon Crumb Bars

Making these Creamy Lemon Crumb Bars is a delightful process that you’ll love. With a few simple steps, you’ll have a treat that is sure to impress. Let’s dive in!
- Line an 8-inch square baking pan with aluminum foil or parchment paper, making sure it hangs over the edges for easy removal later. This will allow you to lift the bars out without any fuss once they’re baked. Set the lined pan aside.
- Preheat your oven to 375 degrees F (190 degrees C). It’s important to have your oven ready, so the bars bake evenly. While it preheats, you can prepare the crust mixture.
- In a medium mixing bowl, stir together the crust and topping ingredients: the melted butter, brown sugar, flour, baking soda, and salt. Use a fork or your fingers to combine until the mixture resembles coarse crumbs. Save ¾ cup of this mixture for the topping later.
- In another medium mixing bowl, mix all the filling ingredients: sour cream, granulated sugar, flour, egg, vanilla extract, and the lemon juice and zest. Use an electric mixer to blend everything until smooth and creamy. The filling should be thick but pourable.
- Press down the remaining crust mixture firmly into the bottom of the prepared pan. This creates a solid base for the filling. Don’t skip this step—make sure it’s compact.
- Pour the creamy filling over the crust, spreading it evenly with a spatula. You want every bite to have that luscious lemon flavor, so take your time with this step.
- Sprinkle the reserved crumb mixture over the filling, covering it evenly for a nice crunchy topping. This will create a delightful contrast in texture.
- Bake in the preheated oven for 25 to 28 minutes. Look for a golden brown topping and a set filling—there should be no jiggly bits in the center when you gently shake the pan. The smell will be incredible!
- Once baked, remove the pan from the oven and allow it to cool completely at room temperature. This step is crucial for cutting clean bars later. Let them rest for at least an hour.
- Using the overhanging foil or parchment paper, lift the bars out of the pan. Cut them into squares or rectangles, and they’re ready to be served!
Things Worth Knowing
