Alisa Fleming ~ This gluten-free coffee cake recipe was shared with us by my friend Colette Martin, from her cookbook Learning to Bake Allergen-Free. All of Colette’s recipes are free of gluten, dairy, eggs, soy, and nuts, and she has tried just about every substitute you can think of!
For this gluten-free coffee cake recipe, Colette recommends using one of the following gluten-free flour blends: Authentic Foods Multi Blend Gluten Free Flour, Jules Gluten Free All Purpose Flour, Authentic Foods GF Classical Blend (includes xanthan gum), or King Arthur Flour Gluten Free Multi-purpose Flour (includes xanthan gum). If you prefer from scratch, she does offer a few homemade flour blends in Learning to Bake Allergen-Free that can be used cup for cup in this recipe.
The technique used here to create the streusel topping is one that is used frequently in Learning to Bake Allergen-Free for making cookie dough and pie crusts. But, you are here for a gluten-free coffee cake recipe, not pie crust, so lets get back to it. From Colette:

Notes
Note that the shortening for the cake is used at room temperature, whereas the shortening for the topping is used cold. Plan to let just the 4 tablespoons sit out to soften and leave the remainder in the fridge until you need it for the streusel.

Gorgeous coffee cake! Thanks so much for sharing, Alisa.
I love that Collette’s recipes are this terrific, but free of so much that many of us can’t tolerate.
