How to Make Oatmeal Lemon Cream Bars
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your bars bake evenly.
Step 2: Prepare the Crust Mixture
In a large mixing bowl:
1. Combine the all-purpose flour, rolled oats, salt, and baking soda. Stir until well mixed.
2. Add both sugars (granulated sugar, light brown sugar) to the dry mixture.
3. Pour in the melted unsalted butter and vanilla extract. Mix until crumbly.
Step 3: Press into Pan
Take about two-thirds of the crust mixture and press it evenly into the bottom of a greased 9×13-inch baking pan to form a solid base.
Step 4: Make the Lemon Filling
In another bowl:
1. Whisk together the sweetened condensed milk, lemon zest, lemon juice, and egg yolks.
2. Add in an additional half teaspoon of vanilla extract. Mix until smooth.
Step 5: Assemble the Bars
Pour the lemon filling over the crust in the baking pan. Spread it evenly with a spatula.
Step 6: Add Remaining Crust Topping
Sprinkle the remaining crust mixture over the top of the lemon filling, covering it as evenly as possible.
Step 7: Bake
Bake in your preheated oven for about 40 minutes or until golden brown on top. The filling should be set when you gently shake the pan.
Step 8: Cool and Serve
Allow your Oatmeal Lemon Cream Bars to cool completely in the pan before cutting them into squares. Enjoy this delicious treat!

Common Mistakes to Avoid
When making Oatmeal Lemon Cream Bars, it’s easy to make a few common errors that can impact the final outcome. Here are some mistakes to watch for:
- Skipping the Zest: Not incorporating lemon zest can dull the flavor. Always remember to zest your lemons for that extra zing!
- Overmixing the Crust: Mixing too much can lead to tough bars. Combine just until ingredients are moistened for a perfect crumbly texture.
- Ignoring Cooling Time: Cutting the bars too soon can cause them to crumble. Allow them to cool completely for clean slices.
- Using Fresh Lemon Juice: Bottled lemon juice lacks freshness. Opt for fresh lemons for the best taste and aroma in your creamy filling.
- Not Measuring Ingredients Accurately: Inaccurate measurements can ruin your recipe. Use proper measuring cups and spoons for precision.
