Ingredient Notes & Helpful Tips
Butter: Make sure your butter is fully softened for easy creaming and a light texture.
Frozen Blueberries: Microwaving them briefly helps soften them so they mix evenly into the dough. Be sure they cool slightly before adding.
Lemon Zest: Fresh zest adds the most flavor. Avoid the white pith, which can taste bitter.
Crumb Topping: This recipe makes a generous amount,
don’t be afraid to pile it on.
Baking Tips for Success
Don’t overmix: Folding gently keeps the cookies tender.
Watch the centers: They should look soft but not wet when you pull them from the oven.
Use parchment paper: This prevents excess browning on the bottoms.
Troubleshooting
My cookies spread too muchThe dough may not have been chilled long enough. Be sure to refrigerate for at least 15–30 minutes before baking. Also double-check that your butter was softened, not melted.
My cookies are dry or crumblyThis usually means too much flour was added. Spoon and level your flour instead of scooping directly from the bag, and avoid overbaking.
The crumb topping fell offLightly press the crumb topping into the dough before baking. This helps it stick without flattening the cookie.
The centers look underbakedThese cookies are meant to be soft in the middle. If they look wet rather than just soft, bake for 1–2 additional minutes or allow them to finish setting on the baking sheet.
The bottoms browned too quicklyMake sure you’re using parchment paper and baking on the center rack. If needed, lower the oven temperature slightly or bake one tray at a time.
My glaze melted or soaked inThe cookies were still warm. Always let them cool completely before drizzling the glaze so it sets nicely on top.
