Frequently Asked Questions

Can I make this recipe gluten-free?

Yes, you can substitute all-purpose flour with a gluten-free flour blend. Ensure the blend contains xanthan gum for proper texture. The baking powder and soda should also be gluten-free. The cake should turn out well, but the texture may differ slightly from the original.

What can I use instead of buttermilk?

If you don’t have buttermilk, you can make a quick substitute by mixing 1 cup of milk with 1 tablespoon of vinegar or lemon juice. Let it sit for about 5 minutes before using. Alternatively, plain yogurt or sour cream can also work as a replacement, diluted with a bit of water if necessary.

Can I freeze the coffee cake?

Yes, this coffee cake freezes well. Allow it to cool completely, then wrap it tightly in plastic wrap and aluminum foil before freezing. It can be stored for up to 2 months. To enjoy, thaw it overnight in the refrigerator and reheat as needed.
