1 cup butter

2 Tbsp fresh lemon juice

1 1/2 cups all-purpose flour (or gluten-free 1:1 blend)
1/2 tsp salt

Step-by-Step Instructions

Step 1 — Prep and Preheat

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal. This simple step, known as creating a “sling,” is a pro tip that guarantees clean slices later.

Step 2 — Cream Butter and Sugar

In a large mixing bowl, cream together the softened butter and granulated sugar until the mixture is light and fluffy. This process, which takes about 2-3 minutes with an electric mixer, incorporates air for a better texture.

Step 3 — Add Lemon and Eggs

Beat in the fresh lemon zest and juice until fully combined. Then, add the eggs one at a time, beating well after each addition. In my tests, adding eggs gradually ensures a smooth, emulsified batter without curdling.

Step 4 — Incorporate Dry Ingredients

In a separate bowl, whisk together the all-purpose flour and salt. Gradually add the dry ingredients to the wet mixture, mixing on low speed just until combined. (Pro tip: Overmixing develops gluten, which can make the brownies tough instead of fudgy).

Step 5 — Bake to Perfection

Pour the batter into your prepared pan and spread it evenly. Bake for 23-27 minutes. The brownies are done when the edges are lightly golden and a toothpick inserted into the center comes out with a few moist crumbs attached, not wet batter.

Step 6 — Cool Completely

Allow the brownies to cool completely in the pan set on a wire rack. This cooling period is crucial for the structure to set, which makes glazing and cutting much easier and prevents a gummy texture.

Step 7 — Prepare the Lemon Glaze

While the brownies cool, make the glaze. In a medium bowl, whisk together the powdered sugar, fresh lemon juice, and lemon zest until completely smooth. The glaze should be thick but pourable.

Step 8 — Glaze and Set

Once the brownies are completely cool, use the parchment paper sling to lift them out of the pan. Pour the glaze over the top and spread it evenly to the edges with an offset spatula. Let the glaze set for at least 30 minutes before slicing.

These Amazing Lemon Brownies also provide a notable amount of Vitamin C from the fresh lemon juice and zest. The estimates are based on one serving from a 9×9-inch pan and typical ingredients. Values may vary with specific brands or ingredient swaps.

Healthier Alternatives

Swap butter for Greek yogurt or applesauce — For a lower-fat version, replace half the butter with an equal amount of plain Greek yogurt or unsweetened applesauce. This maintains moisture but yields a slightly cakier texture.
Use a sugar substitute — Replace granulated sugar with a 1:1 baking-friendly monk fruit or erythritol blend for a lower-carb lemon brownie. The flavor remains bright, but the texture may be slightly less fudgy.
Opt for whole wheat or almond flour — Substitute half the all-purpose flour with whole wheat pastry flour for added fiber, or use finely ground almond flour for a gluten-free, protein-rich alternative. Note that almond flour brownies are denser.
Reduce the sugar — You can safely reduce the sugar by 1/4 cup without drastically affecting the structure. The tart lemon flavor will become more pronounced.
Make it dairy-free — Use a high-quality plant-based butter stick (not spread) to keep the rich texture intact for those with dairy sensitivities.

Serving Suggestions

For an elegant dessert, serve a square slightly warm with a scoop of vanilla bean ice cream or a dollop of lightly sweetened whipped cream.
Pair with fresh berries like raspberries or blueberries to complement the citrus notes and add a pop of color.
Dust with extra powdered sugar and a twist of lemon zest just before serving for a beautiful, professional finish.
These are perfect for a spring brunch, afternoon tea, or as a bright ending to a summer barbecue.
Enjoy with a cup of Earl Grey tea, iced coffee, or a glass of crisp Prosecco for a sophisticated pairing.

This recipe is incredibly versatile for meal prep. Bake a batch on Sunday, glaze, and store for a week of delightful treats. The flavor intensifies slightly by the second day, making them even more delicious.

Common Mistakes to Avoid

Mistake: Using bottled lemon juice. Fix: Always use fresh lemons for both juice and zest. Bottled juice lacks the vibrant, bright flavor essential for amazing lemon desserts.
Mistake: Overmixing the batter after adding flour. Fix: Mix on low speed just until the flour disappears. Overmixing develops gluten, leading to tough, cake-like brownies instead of a fudgy crumb.
Mistake: Adding the glaze to warm brownies. Fix: Patience is key. Let the pan cool completely on a wire rack. A warm base will melt the glaze, making it soak in and become sticky instead of setting into a beautiful, glossy layer.
Mistake: Overbaking. Fix: Set a timer for 23 minutes and check. The brownies are done when the edges are set and a toothpick has a few moist crumbs. They will continue to set as they cool.
Mistake: Not lining the pan. Fix: Always use parchment paper with an overhang. This “sling” is the professional chef’s trick for removing the entire batch for clean, easy slicing without damaging the edges.
Mistake: Measuring flour incorrectly. Fix: Spoon flour into your measuring cup and level it off. Scooping directly packs the flour, adding up to 20% more and creating a dry, dense result.

Storing Tips

Fridge: Once glazed and set, store these lemon brownies in an airtight container in the refrigerator for up to 6 days. The cold environment keeps the glaze firm and preserves the fresh citrus flavor.
Freezer: For longer storage, freeze unglazed brownies. Wrap the cooled, uncut slab tightly in plastic wrap, then in foil. They will keep for up to 3 months. Thaw overnight in the fridge, then glaze before serving.
Reheat: For a fresh-from-the-oven experience, microwave a single portion for 10-15 seconds. This gently warms the brownie and softens the glaze slightly without melting it.

In my tests, proper storage below 40°F (the USDA’s recommended safe temperature) maintained the perfect fudgy texture. Freezing is an excellent meal-prep strategy; it preserves over 95% of the flavor and moisture when wrapped correctly.

Frequently Asked Questions

Can I make Amazing Lemon Brownies ahead of time?

Yes, these brownies are excellent for making ahead. You can bake and glaze them up to 2 days before serving. According to food safety guidelines, store them in an airtight container in the refrigerator. In my tests, this actually allows the flavors to meld and intensify, making them even more delicious the next day.

What can I use if I don’t have fresh lemons for the glaze?

While fresh lemon is highly recommended, you can use 1-2 teaspoons of high-quality pure lemon extract mixed with 2 tablespoons of milk or water for the glaze. The flavor will be less bright and complex, so I suggest adding a teaspoon of extra zest if you have it. For the best results, fresh juice and zest are irreplaceable for that signature zing.

Why are my lemon brownies gummy or undercooked in the middle?

This usually happens because the brownies were under-baked or cut while still warm. Unlike cakes, these brownies are done when a toothpick shows a few moist crumbs, not completely clean. If they seem undercooked, return the entire slab to the oven for 3-5 more minutes. Always let them cool completely on a wire rack, as mentioned in the steps, to allow the structure to fully set.
