Instructions
- If using fresh lemon juice, squeeze lemons into a small bowl. Skip this step if using lemon juice from the bottle.
2. With a small grater, grate the yellow squash into a small bowl and set aside. I like using a finer grater so the yellow squash pieces aren't as big.
3. In a stand mixer, combine the dry ingredients and mix until well incorporated.
4. In a separate bowl, add the wet ingredients. Mix well until it is a smooth mixture.
5. Pour the mixed wet ingredients into the stand mixer bowl with the combined dry ingredients. Combine the wet and dry ingredients to make a batter.
6. Add grated yellow squash, lemon zest (optional), and poppyseeds into the batter. Mix well until both the poppyseeds and yellow squash are incorporated.
7. Divide the batter into 12 equal muffin liners or a well greased muffin tin.
6. Bake for 15 minutes or until the center is set. Remove from the muffin tin and enjoy!
Hint: Yellow squash is the same as summer squash and crooked neck squash! So if you have summer squash ready to be used, this is a perfect recipe for you. Or try this same recipe with zucchini.
Substitutions

Equipment
To make these delicious homemade muffins you will need a stand mixer, muffin tin, and muffin liners. I love using silicone muffin liners and my KitchenAid Stand Mixer.
Storage
Store muffins in an airtight container for 3-4 days. They are better fresh, but if they are several days old, reheat in the microwave for 10-15 seconds.
Freeze in an air tight container for up to 1 month. Thaw in the refrigerator and then reheat in the microwave for 10-15 seconds.
Toddler Friendly
These are a perfect muffin for little hands. These toddler friendly muffins are healthier than other muffins, have yellow squash in them that can easily go undetected for picky eaters. My kids eat these up without blinking and eye!
Top tip
Because yellow squash is abundant in the summer, make the night before when it's cooler outside as to not run the hot oven during the heat of the day. You will have a delicious breakfast ready in the morning. A great make ahead treat or meal.

- A great way to check for doneness is to put a toothpick down the center of a muffin and if it comes back clean, they are done.
- Another helpful way is to lightly tap the top center of the muffin. It should bounce back and not cave down.
