Zucchini Pineapple Crumble Top Muffins

Zucchini is one of those garden plants that always seem like a good idea to plant until you’re harvesting 4-5 a day with no end in sight. I personally love pan frying my zukes with a little bit of onion and finishing it with a dusting of parm, but sometimes you just need something to satisfy your sweet tooth (and also to eat for breakfast…)

Zucchini-to shred or purée?

Most zucchini recipes I find call for shredded zucchini. And that is a perfectly fine way to make this recipe. It’s very easy, simply peel the zucchini and then shred it with a box grater or the shredding disk on your food processor.

I personally am super lazy so I just take my zucchini for a spin in the food processor. It makes the zucchini more of a purée, like applesauce. Which makes for a smoother batter and no bits of zucchini in the final baked muffin. This sometimes makes things a little easier when feeding them to small people who are skeptical of things like vegetables in their muffins.

When you have way too much zucchini…

Zucchini is one of those wonderful vegetables that can be frozen. I like to freeze my purée in 2 cup portions. I simply bag up 2 cups, remove the air, and freeze. Then when I NEED some zucchini pineapple muffins in the middle of winter, I can thaw a bag and whip up a batch.

A few notes on muffins:

Muffins come together quickly in one bowl using only a spoon or whisk to stir. You stir together the wet ingredients and then fold in the dry ingredients, leaving lumps in the batter (a batter that is too smooth will create a uniform crumb, more like a cake). *Sugar acts like a wet ingredient when making muffins or quick breads because it melts when it’s baked.

Muffins also typically rely on chemical leaveners to help achieve height. In this case we’re looking at both baking soda and baking powder.
