Cinnamon
Ground cinnamon adds warm flavor to the sweet crumb topping.
Milk
Regular dairy milk works well, but your preferred milk alternative can also be used.
How to Make Easy Blueberry Coffee Cake
1. Preheat the Oven
Preheat your oven to 350°F.
Grease an 8-inch or 9-inch square baking dish or line it with parchment paper.
2. Make the Crumb Topping
In a small bowl, combine:
- Flour

Mix until evenly combined.

In a separate bowl, whisk together:
- Egg
- Milk
- Melted butter
- Vanilla extract
Mix until smooth.
5. Combine the Batter
Pour the wet ingredients into the dry ingredients.
Gently stir until just combined.
Do not overmix.
The batter should be thick.
6. Add the Blueberries
Gently fold the fresh blueberries into the cake batter.
Be careful not to crush them.

Tips for the Best Blueberry Coffee Cake
Don’t Overmix the Batter
Mix only until the ingredients are combined.
Overmixing can make the cake dense.
Use Fresh or Frozen Blueberries
Both work well.
If using frozen blueberries, add them directly from the freezer.
Toss Blueberries with Flour
If your blueberries tend to sink, gently toss them with 1 teaspoon of flour before folding them into the batter.
Use Cold Butter for the Crumb Topping
Cold butter helps create a crumbly, bakery-style topping.
Check the Cake Before Removing It
Start checking the cake around 40 minutes.
Baking times can vary depending on your oven and baking dish.
