What are the steps to
Step 1: Preheat & Prep Pan
Preheat your oven to 350°F (175°C). Grease and lightly flour an 8×8 inch baking pan. If you want to remove a piece of paper, line it with parchment paper. I find the parchment paper makes cleanup a snap! Do this first so you are not scrambling later.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the flour, sugar, baking powder, and salt. Set aside. Make sure everything is well combined. This helps to distribute the baking powder evenly, which is important for a good rise.
Step 3: Cut in Butter
How do you cut butter in a pastry blender or your fingertips until the mixture resembles coarse. The smaller the pieces of butter the better. The cold butter is what makes it nice and crumbly. This is crucial for that perfect texture!
Step 4: Add Wet Ingredients
In a small bowl, whisk together the egg and vanilla extract. Set aside. Add flour mixture and mix until just combined. Do not overmix! Overmixing will develop the gluten and make the base tough. It should be crumbly, not a dough ball.
Step 5: Press into Pan
Press the mixture into the prepared pan. I like to use the bottom of a measuring cup to get nice and even. Don’t worry if it looks a little crumbly, it will bake up perfectly.
Step 6: Prepare Filling
In a medium bowl, whisk together the flour, salt, and sugar for the lemon filling. Add the lemon juice, eggs, melted butter, and lemon zest. Whisk until smooth. What is the zest of lemon?
Step 7: Pour Filling
What’s the best way to spread the lemon filling over the crust?
Step 8: Make Streusel
In a small bowl, combine the flour, brown sugar, and cinnamon (if using) for the streusel topping. How do you cut butter into coarse crumbs?
Step 9: Sprinkle Streusel
Sprinkle the streusel topping evenly over the lemon filling. Don’t be shy, you want a good layer of crumble!
Step 10: Bake
Bake for 30-35 minutes, or until streusel is golden brown and filling is set. Is it true that a toothpick inserted into the center should come out clean?
Step 11: Cool and Glaze
Let the squares cool completely in the pan before glazing. If they are still warm, the glaze will melt. This is important because if they’re not, they will not be able to keep up with the temperature. In a small bowl, whisk together the powdered sugar, milk (or lemon juice), and vanilla extract. Set aside. How do I use) until smooth. Drizzle over the cooled squares.
Step 12: Slice and Serve
Slice into squares and serve. Enjoy every single bite! I like to cut them into smaller squares, because they are pretty rich. What is the best way to prepare this recipe for slicing? What makes them less gooey and easier to cut?

Top Tips for Perfecting Your Lemon Streusel Squares
Okay, friends, I’ve made these lemon streusel squares countless times, so I’ve learned a few tricks along the way to ensure they turn out perfectly every time:
Butter Temperature: The key to a good crumble is cold butter! Make sure your butter is very cold when you cut it into the flour mixture for both the base and the streusel. This creates those little pockets of fat that melt during baking, resulting in a tender, crumbly texture.
Mixing Advice: Don’t overmix the base! Overmixing will develop the gluten in the flour, resulting in a tough base. Mix until just combined, and don’t worry if it’s a little crumbly.
Zest is Best: Don’t skimp on the lemon zest! The zest is where all the lemon flavor is concentrated. Make sure to zest your lemons before you juice them, and use a microplane or fine grater to get the most flavor.
Ingredient Swaps: If you don’t have brown sugar for the streusel, you can use granulated sugar instead. It will still be delicious, but the brown sugar adds a nice molasses flavor.
Baking Tips: Keep an eye on the squares while they’re baking. Ovens can vary, so they may need a few extra minutes or a few minutes less. You want the streusel to be golden brown and the filling to be set.
Glaze Variations: For an extra lemony glaze, use lemon juice instead of milk. You can also add a teaspoon of lemon zest to the glaze for even more flavor. I also tested a glaze made with orange juice once. It was pretty amazing!
I also learned the hard way that you really do need to let them cool completely before glazing. Otherwise, you end up with a sticky mess. Trust me on this one!
Storing and Reheating Tips
Here’s how to keep your lemon streusel squares fresh and delicious:
Room Temperature: You can store them at room temperature in an airtight container for up to 2 days. Make sure they’re covered to prevent them from drying out.
Refrigerator Storage: For longer storage, keep them in the refrigerator in an airtight container for up to 5 days. They’ll be a little denser when cold, but still delicious!
Freezer Instructions: You can also freeze them for up to 2 months. Wrap them tightly in plastic wrap, then place them in a freezer-safe container. Thaw them overnight in the refrigerator before serving.
Glaze Timing Advice: I recommend glazing them right before serving for the best results. If you glaze them ahead of time, the glaze may become a little sticky.
I always make a double batch and freeze half for later. It’s so nice to have a sweet treat on hand whenever a craving strikes!
