Treats with Summer Squash

When I planted our summer squash,  I made sure to do two yellow squash plants:  a crooked neck and a yellow zucchini.  I knew only one green zucchini plant would be enough.  I didn’t realize that the yellow squash would grow faster than the green ones!   So here is a recipe for a “not too sweet” coffee cake to use up that extra summer squash from the garden.

Summer Time 2020

This is certainly a strange year due to COVID19,  and I miss all my former activities directing choirs and playing in a community band,   but I’m grateful to be home on the ranch,  growing a garden, and using this time to make new friends through my blog!   Let me know if you try my recipes, and share photos on Instagram.  If you hashtag #MimiAvocado I’ll see them!
