The thing I like about coffee cake is that it isn’t just for breakfast or brunch, it’s also nice to whip up for a homey weeknight dessert. Our whole family adores the strawberry rhubarb combination in this coffee cake, with our homegrown rhubarb and fresh strawberries from Wegmeyer Farms, and the crispy topping and the holes in the top crust, which fill up with ice cream or whipped cream like floating puddles of milky goodness. It’s a dream of a cake that’s easy to make and perfect for a family meal.
If you don’t have buttermilk, you can make an easy substitute. Just stir together 1 tablespoon lemon juice with enough milk to make 1 cup, then allow it to rest at room temperature for about 10 to 15 minutes before using.
