Wow, 3.5 year old twin boys!!! You must be a master of thriving amid chaos!
I have a 7 year old daughter, who sometimes helps out with baking. Because of my baking habit, she has developed very discerning tastes and won’t eat shortening-based frostings and the like. Her favorite thing is to wield the pastry bag. She’s good at making drop stars.
Her favorite Cake Bible dessert is an apple variation of the Pineapple Upsidedown Cake, though really she loves anything made with the Sour Cream Butter Cake.
Even with just one child, though, I often will prep things after she goes to bed. And I love making things like the Brioche, which can be made in steps spread out over three or four days. It’s hard to find large blocks of time for time-sensitive projects.
