Ingredients and Preparation
Hereโs what youโll need to make these delightful oatmeal lemon crรจme bars:
- Old-Fashioned Oats: The base of the bars, offering a hearty and chewy texture. Oats are a great source of fiber, which helps with digestion and keeps you feeling full longer.
- Flour: All-purpose flour helps to bind the oats together and gives structure to the bars. You can substitute it with whole wheat flour for added nutrition.
- Butter: Adds richness and flavor to the crust. It also helps in holding the oats and flour together.
- Sugar: A little sugar is added to sweeten the oatmeal base. You can replace it with honey, maple syrup, or a sugar alternative if you prefer.
- Eggs: Eggs are crucial for binding the ingredients and creating a soft, cakey texture in the bars.
- Lemon Juice and Zest: The star of the recipe, providing the signature tartness and freshness that makes these bars stand out. Lemon is rich in vitamin C and antioxidants, making these bars a healthy treat.
- Sweetened Condensed Milk: This creamy filling is what gives the bars their smooth texture and sweetness, creating a rich lemon crรจme layer that contrasts beautifully with the oatmeal base.
Alternative Ingredients:
- You can swap the sweetened condensed milk with coconut milk or another dairy-free alternative if you want a non-dairy version of the bars.
- If you donโt have lemon or prefer a different citrus, lime would work well as a substitution for the lemon juice and zest.
Step-by-Step Instructions
Step 1: Preheat your oven to 350ยฐF (175ยฐC). Grease a 9ร13-inch baking pan or line it with parchment paper for easy removal of the bars after baking.
Step 2: In a large mixing bowl, combine the old-fashioned oats, flour, butter, sugar, and eggs. Use a spoon or your hands to mix everything together until it forms a crumbly dough. This mixture will be used as the base of the bars.
Step 3: Press about 3/4 of the oat mixture into the prepared pan, spreading it evenly to form a crust. Set the remaining oat mixture aside for the topping.
Step 4: In a separate bowl, whisk together the sweetened condensed milk, lemon juice, lemon zest, and egg. Pour this lemon crรจme filling over the oatmeal crust, spreading it evenly with a spatula.
Step 5: Sprinkle the remaining oat mixture over the lemon filling, covering it evenly.
Step 6: Bake the bars in the preheated oven for 25-30 minutes, or until the top is golden brown and the lemon filling is set. The filling should slightly firm up, but still be a bit soft in the center when you remove the pan from the oven.
Step 7: Allow the bars to cool completely in the pan before slicing. This will help the lemon filling set and make it easier to cut the bars into neat squares.
Beginner Tips and Notes
- Donโt overmix the oat crust: When youโre mixing the oats, flour, butter, sugar, and eggs, be careful not to overwork the dough. You want it to be crumbly but still able to hold together. Overmixing can make the texture too dense.
- Let them cool completely: As tempting as it may be to dig in right away, be sure to let the bars cool completely. This ensures the filling has time to set, making it easier to cut the bars into perfect squares.
- Adjust the sweetness: If you prefer a less sweet treat, you can reduce the amount of sugar or condensed milk in the recipe, as the lemon filling will provide plenty of natural sweetness.
- Storage: If you have leftover bars, store them in an airtight container at room temperature for up to 3 days, or refrigerate them for a longer shelf life. You can also freeze them for up to a month.
Serving Suggestions
These oatmeal lemon crรจme bars can be enjoyed on their own, but here are a few ways to elevate the experience:
- Serve with a dollop of Greek yogurt on the side for a creamy, tangy contrast to the sweetness of the bars.
- Pair with a hot cup of tea or coffee for a comforting breakfast or afternoon snack.
- Add a sprinkle of powdered sugar or a drizzle of honey for an extra layer of sweetness.
Storage Tips: If you have leftovers, store the bars in an airtight container. Theyโll keep for up to 3 days at room temperature, or up to a week in the refrigerator. For longer storage, you can freeze them for up to a month. Just be sure to wrap them well in plastic wrap or store them in a freezer-safe container.
