Kitchen Tools You’ll Need
- 8” square baking dish
- Parchment paper
- Cooking spray
- Medium-sized mixing bowl
- Hand mixer
- Toothpick
- Knife
Ingredients
- 1 15.25 oz box of yellow cake mix (provides a soft, cake-like texture)
- 1 box lemon instant pudding (adds moisture and a rich lemon flavor)
- 1/3 cup lemon juice (contributes acidity and brightness)
- 2 large eggs (binds ingredients and adds structure)
- 1 teaspoon lemon zest (optional for enhanced citrus flavor)
- 1 cup powdered sugar (sweetens and creates a smooth glaze)
- 1 tablespoon lemon juice (for glaze, adds tartness)
- Lemon zest for garnishing (optional, adds a fresh touch)
How to Make Lemon Brownies
Step 1. Start by lining an 8-inch square baking dish with parchment paper, ensuring you leave some overhang. This will help lift the brownies out easily once they’re baked. Spray the lined dish with cooking spray to prevent sticking.
Step 2. Preheat your oven to 350 degrees. This ensures the brownies will bake evenly and helps achieve a light golden color on the edges as they rise and set during baking.
Step 3. In a medium-sized mixing bowl, combine the yellow cake mix, lemon instant pudding, lemon juice, eggs, and lemon zest if you’re using it. Using a hand mixer, blend on low to medium speed until the mixture is smooth and free of lumps, achieving a thick yet pourable batter.
Step 4. Pour the batter into the prepared baking dish and use a spatula to spread it evenly across the pan. This helps the brownies bake uniformly, so every piece has the same delicious texture and flavor.
Step 5. Place the baking dish in the preheated oven and bake for 22 to 24 minutes. Check for doneness by inserting a toothpick into the center; it should come out clean or with a few crumbs—this indicates the brownies are ready.
Step 6. Once baked, remove the dish from the oven and allow the brownies to cool in the pan for about 10 minutes. This slight cooling helps them set without becoming overly dry.
Step 7. Carefully lift the brownies out of the pan using the parchment paper overhang and place them on a wire rack to cool completely. This cooling step is essential for achieving the right texture when you cut them into squares.
Step 8. To make the glaze, mix the powdered sugar with the tablespoon of lemon juice in a small bowl until smooth. The glaze should be pourable but thick enough to stay on top of the brownies.
Step 9. Drizzle the glaze over the cooled brownies, allowing it to gently coat the top. For an added touch, sprinkle some lemon zest on top to enhance the citrus aroma and brightness.

Serving Suggestions
These lemon brownies are versatile and can be enjoyed in various ways. They make a refreshing breakfast option or a perfect snack alongside your afternoon coffee or tea.

Pro Tips for Best Results
- Use fresh lemon juice: This enhances the flavor and brightness of the brownies.
- Don’t overmix the batter: Mix just enough to combine the ingredients to keep the brownies light and fluffy.
- Test the brownies early: Ovens can vary, so checking a bit earlier ensures you don’t overbake them.
- Let them cool completely: This helps the texture firm up, making them easier to cut into clean squares.
- Adjust glaze consistency: If the glaze is too thin, add a bit more powdered sugar until you achieve the desired thickness.
- Try with or without lemon zest: Experimenting with or without the optional zest will allow you to adjust the lemon intensity to suit your taste.
Common Mistakes to Avoid
- Overbaking the brownies: This can lead to a dry texture. Keep an eye on them during the last few minutes and check doneness early.
- Not lining the baking dish: This makes it difficult to remove the brownies cleanly. Always use parchment paper for easy lifting.
- Ignoring the cooling step: Cutting into warm brownies can lead to a gooey mess. Always let them cool completely before slicing.
- Forgetting to add eggs: Eggs are crucial for binding the ingredients. Make sure to include them for the right texture.
- Not using a toothpick test: Skipping this step can result in either undercooked or overcooked brownies. Check for doneness to get the perfect bake.
- Lacking proper storage: Leaving brownies uncovered may dry them out. Store them in an airtight container to keep them fresh.
Variations & Substitutions
If you feel adventurous, you can modify the lemon flavor to your liking. You might consider adding a handful of white chocolate chips for added sweetness and creaminess. Alternatively, swapping the yellow cake mix for a gluten-free option allows those with dietary preferences to enjoy this treat.
Storage & Reheating
These lemon brownies can be stored at room temperature in an airtight container for about 2 to 3 days. If you want to keep them longer, they can be refrigerated for up to a week.
