Let’s Make it Together
Preheat Your Oven: Start by preheating your oven to 350°F (175°C). Meanwhile, grab a 9×13-inch baking dish and lightly grease it to prevent sticking.
Combine Lemon Goodness: In a bowl, mix together fresh lemon juice and zest with granulated sugar and water until well blended. The mixture should smell heavenly!
Add Cake Mix and Butter: Spread dry cake mix evenly over the lemon mixture in the baking dish. Then melt your butter and drizzle it generously over the top—no need to stir! It will work its magic while baking.
Bake Until Golden Brown: Pop that beauty into your preheated oven and let it bake for about 45 minutes or until golden brown on top. The aroma will have everyone asking what’s cooking!
Cool and Dust with Sugar: Once baked, take it out to cool slightly. If you’re feeling fancy, sprinkle some powdered sugar on top before serving—it’s like giving your cake a little snow shower.
Enjoy each slice warm or chilled; either way, it’s pure bliss!
