Karlynn’s Recipe Notes
- Skill Level: This is a very easy recipe.
- Total Time: This cake takes approximately 60 minutes to make.
- Variations: Try this cake with different berries, or even mixed berries. Use whichever nuts you like best, mix some right into the cake, or skip them entirely if you don’t enjoy them.
- Tools Needed: For this recipe, you’ll need two medium bowls, a small bowl, a pastry cutter or fork, a whisk, and a 9×9 baking pan.

What You’ll Need For Ingredients
Sour Cream: Sour cream is the best ingredient for moist and tender coffee cake. Its acidity helps tenderize the gluten strands in coffee cake, making it soft and tender. If you haven’t got sour cream, plain yogurt will work for this purpose.
Nuts: This recipe calls for walnuts, which are common in coffee cakes and are usually more affordable than other nuts. Pecans also work well and even slivered almonds or filberts would be an excellent choice for the topping in this recipe.
Blueberries: Fresh or frozen should both be fine for this recipe. If you haven’t got blueberries handy, you could try a different type of berry. Strawberries, cut up small, would be lovely, as would raspberries or blackberries.

This is a brief overview of the recipe. The full list of ingredients and step-by-step instructions are in the recipe card below.
- Preheat oven to 350°F. Grease 9×9 pan and set aside.

Storage Instructions
Once it’s fully cooled, you can store this coffee cake at room temperature for 2-3 days. The streusel topping will help it not to dry out, but you may want to cover it at least loosely. Eat at room temperature or warm it up in the microwave for a few seconds.
Freezer: Freeze individual slices of coffee cake, separated by pieces of wax paper or parchment paper, in a sealed container for 3-4 months. That way you can take out and defrost individual slices. You can warm it up in the microwave or eat it cold.
