Step by Step Instructions for Microwave Lemon Bars

Making Microwave Lemon Bars is a breeze! Follow these simple steps to create a luscious treat that will impress everyone. It’s all about layering the flavors and baking them to perfection. Let’s get started!
Lightly grease a 9×9 inch microwave-safe baking dish or line it with parchment paper for easy removal. This ensures that your Microwave Lemon Bars won’t stick.
In a mixing bowl, whisk together 1 cup of all-purpose flour, 3 tablespoons of powdered sugar, and 1 tablespoon of lemon zest. This combination will form the base of your crust, so make sure it’s well mixed.
Stir in 6 tablespoons of melted butter until the mixture resembles wet sand. This will create a crumbly yet cohesive crust.
Press the crust mixture into the prepared baking dish evenly, ensuring it’s tightly packed. The crust should be slightly thicker at the edges.
Microwave the crust on high for three minutes at 80% power. After three minutes, check to see if it’s firm to the touch. If it’s still soft, heat for an additional 30 seconds at 80% power. Set aside to cool.
In a separate bowl, beat together 1 cup of granulated sugar, 2 tablespoons of lemon zest, 3 large eggs, and 1/3 cup of fresh lemon juice until well combined.
Add in 1 tablespoon of all-purpose flour, 1/2 teaspoon of baking powder, and 1/4 teaspoon of salt. Continue beating for another 2 to 3 minutes until the mixture is smooth and slightly thickened.
Pour the lemon filling over the cooled crust in the baking dish, making sure it’s evenly distributed. This will create that luscious top layer that defines your Microwave Lemon Bars.
Microwave the bars for three minutes at 80% power. Check the center; it should be set with a slight jiggle, similar to Jell-O. If it isn’t set, microwave for an additional minute at 80% power and check again.
Once done, allow the lemon squares to cool completely at room temperature. Then, refrigerate them for several hours or overnight to set properly.
Finally, cut into squares, dust with powdered sugar, and sprinkle additional lemon zest on top if desired. Keep these delicious treats refrigerated until serving!
Things Worth Knowing
- Use a microwave-safe dish: Ensure your baking dish is specifically labeled for microwave use to avoid any mishaps.
- Check for doneness: The filling should be just set; it can continue to firm up as it cools.
- Chill before serving: This allows the flavors to meld and enhances the texture of the bars.
- Experiment with zest: Feel free to use zest from other citrus fruits for a unique twist.
Change It Up

If you’re looking to personalize your Microwave Lemon Bars, here are some fun tips to consider:
- Add a berry twist: Mixing in fresh blueberries or raspberries can provide a delightful contrast to the lemon flavor.
- Adjust the sweetness: Feel free to reduce the sugar for a less sweet but still delicious treat.
- Top with whipped cream: A dollop of whipped cream adds richness and makes for an elegant presentation.
- Infuse with herbs: Try adding a hint of mint or basil to elevate the flavor profile.
- Experiment with gluten-free options: Use gluten-free flour to make these bars suitable for those with dietary restrictions.
- Serve with a fruit compote: Pair these bars with a homemade fruit compote for a fresh and vibrant dessert.
