What You Need to Bake

• Mix-Ins and Substitution Ideas

• For some crunch and nuttiness, fold ½ cup chopped walnuts or pecans into the batter or sprinkle them on top before baking.
• Use melted butter instead of vegetable oil for a richer, buttery flavor—just swap it 1:1.
• Want muffins instead? Pour the batter into a lined muffin tin and bake for 18 to 22 minutes. Perfect for grab-and-go snacks.
• If you’re not a lemon fan, try swapping lemon zest and juice for orange for a sweeter, milder citrus taste.
• Make it a bit heartier by replacing up to half a cup of the flour with whole wheat flour.

Storing, Freezing, and Reheating

• At room temperature, keep your Lemon Zucchini Coffee Cake covered tightly with a cake dome or in an airtight container. It stays fresh for about 2 to 3 days.
• If you want it to last longer, refrigerate it for up to 5 to 7 days. Just bring it back to room temperature before serving to enjoy the best flavor.
• Freeze individual slices or the whole cooled cake wrapped tightly in plastic wrap and foil. It keeps well for up to 2 months. Thaw it in the fridge overnight or on the countertop for a few hours.
• To warm up, pop slices in the microwave for 10 to 20 seconds or heat in a 325°F (160°C) oven for 8 to 12 minutes until warmed through.

Answers to Common Questions

• Can I swap yellow squash for the zucchini? Absolutely! Yellow summer squash works just as well and you can use it one-to-one.
• Do I need to peel the zucchini? Nope! Keeping the peel on saves prep time and adds nice color and nutrients. Just wash it well before shredding.
• Is it possible to make this gluten-free? Yes, just replace the all-purpose flour with a 1:1 gluten-free baking flour. Watch the texture as gluten-free blends can vary, and you might need to reduce baking time slightly or add a bit of xanthan gum if your blend doesn’t include it.
• Why is my cake soggy in the middle? Usually from too much moisture in the zucchini or not baking long enough. Make sure to squeeze the shredded zucchini well and test with a toothpick before taking it out.
• Can I prep this ahead of time? You can! Bake it a day ahead and keep it covered at room temperature or in the fridge. Slices also freeze well for longer storage.
