Recipe Steps
Step 1
Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan. This will ensure your cake doesn’t stick and comes out easily.
Step 2
Cream together the butter and sugar in a large bowl until light and fluffy. This process incorporates air and helps the cake rise.
Step 3
Add the eggs one at a time, mixing well after each addition. Stir in vanilla extract and lemon zest if using for added flavor depth.

Storage Options
Keep your leftover coffee cake at room temperature, wrapped tightly in plastic wrap or stored in an airtight container, to retain its moist texture for up to three days. To freeze, wrap each slice individually in plastic wrap and place in a freezer-safe bag. To enjoy, let it thaw at room temperature or warm it up in the oven at 350°F for about 10 minutes.
Variations & Substitutions
For a healthier twist, try using whole wheat flour or a mixture of whole wheat and all-purpose flour. Substitute sugar with coconut sugar or a sweetener of your choice. You can also swap blueberries for raspberries or sliced apples for a different flavor variation. Feel free to add nuts or oats to the streusel for extra crunch.
Serving Suggestions

Frequently Asked Questions
Can I use frozen blueberries? Yes, you can use frozen blueberries. Do not thaw them before adding as it can introduce extra moisture to the batter. Simply toss them in a bit of flour to prevent sinking and fold them in carefully.

Can I make this cake ahead of time? Absolutely! This cake can be made a day in advance. Allow it to cool completely, then cover securely. Its flavors often deepen after a day, making it even more delicious.
