A Must-Bake Summer Cake

I’m gonna get straight to it on this one, y’all! This Zucchini Cake with Cinnamon Cream Cheese Frosting is amazing! A must-bake this summer while zucchini is in abundance!

This cake is so moist from 2 packed cups of shredded zucchini. And it’s perfectly sweet from the rich cream cheese frosting. A hint of cinnamon in both the cake and frosting brings it to a whole new level of deliciousness that you just have to taste to believe!

We’re pretty much eating zucchini at every meal these days because it’s so cheap, fresh and nutritious! I shred it into pancakes for breakfast, cut it into sticks for dipping in hummus at lunch, grill it alongside chicken breasts for dinner, and of course, bake it into a yummy cake that we can eat for dessert all week long!

Perfect Cinnamon Cream Cheese Frosting

Icing, Frosting and Glaze: What’s the difference?

What’s the difference between icing, frosting and glaze? It’s so easy to get confused! Because depending on where you’re from, these terms might be used interchangeably. Frosting is soft and spreadable.

The difference between it and icing is mostly texture and what you do with it. But here’s a crash course on the differences between icing, frosting and glaze and when to use them.

Icing is thin, made from powdered sugar, milk and sometimes a flavoring, like vanilla. It firms up as it dries but stays pliable. You drizzle icing on cinnamon rolls and scones.
Glaze is also thin but it hardens almost completely as it dries. It’s typically made from powdered sugar, sometimes butter, and a liquid (like milk, water, or juice). You glaze a donut.
Frosting is soft, creamy and spreadable. It’s usually made from butter or cream cheese, confectioners sugar and flavorings. You frost cakes and cupcakes.

This cake can be frozen for up to 2 months, but I recommend slicing it into individual slices and wrapping each slice in plastic wrap to protect it from freezer burn.
