Ingredients

Below is an overview of the ingredients and instructions for this recipe. Be sure to scroll down to the recipe card below for the complete details! 

Cake Batter

  • All-Purpose Flour – If needed, you can substitute a 1:1 gluten-free all-purpose flour to keep this recipe gluten-free. 
  • Granulated Sugar – You can substitute monk fruit sweetener to keep the sugar content lower. 
  • Baking Powder (aluminum free) – Make sure it’s fresh! This helps the cake become light and fluffy. 
  • Eggs – These add a richer flavor and provide structure to the cake, helping it hold its shape. 
  • Milk – Whole milk will yield the richest taste, but low-fat or dairy-free milk will also work. 
  • Melted Butter – Unsalted butter is best. Or, opt for plant-based butter if needed. 
  • Blueberries – Use fresh blueberries or frozen blueberries! 

Streusel Topping

  • Flour – Forms the base of the topping. Again, if needed, gluten-free flour will work. 
  • Sugar – We don’t recommend using a sugar substitute for the topping as it tends to become grainy. 
  • OatmealRolled oats add a satisfying crumbly texture. 
  • Butter – Adds a rich flavor.

Instructions

Before you begin, be sure to preheat your oven, and grease a glass pan with non-stick cooking spray! 

  1. Mix the dry ingredients. Add the flour, baking powder, sugar, and salt in a large mixing bowl. Set it aside. 
  2. Whisk the wet ingredients. In a separate bowl, whisk the milk, melted butter, and eggs. 
  3. Combine the wet and dry ingredients. Pour the wet ingredients into the bowl with the flour mixture. Mix just until no streaks remain. 
  4. Transfer. Pour the cake batter into the prepared pan. Sprinkle the blueberries on top, and set it aside. 
  5. Prepare the topping. In a third bowl, add all the ingredients for the topping. Use a pastry cutter, fork, or your hands to cut the butter into the mixture. A crumbly, sand-like texture will form! 
  6. Add the topping. Sprinkle the crumb topping evenly on top of the cake batter. 
  7. Bake. Transfer the pan to the oven, and bake until the cake is fluffy. A toothpick inserted into the center should come out clean. 
  8. Cool. Allow the cake to cool slightly. Then, slice, and serve!

Flavor Variations 

Feel free to experiment with different ingredients and flavor combinations to make this blueberry coffee cake recipe your own! 

  • Swap the Berries – Replace the blueberries with any other berries you like best such as strawberries, raspberries, or blackberries. 
  • Add Extracts – Incorporate vanilla extract or almond extract for extra depth. 
  • Include Spice – Add a dash of cinnamon, nutmeg, or allspice to incorporate warmth into the cake. 
  • Add Citrus – Mix lemon juice or lemon zest into the batter for a refreshing touch of citrus. 
  • Make Muffins – Pour the batter into a greased muffin pan instead! Fill the cups ⅔ of the way full, and adjust the baking time as needed for blueberry coffee cake muffins. 

How to Store

Once cooled, you can store leftover coffee cake in an airtight container at room temperature for up to three days

You can also freeze leftovers for up to three months! To do so, double-wrap the cake with plastic wrap and aluminum foil, and transfer it to a sealable bag. Thaw in the fridge overnight before serving.

Notes

Substitutes – Monk fruit sweetener may be substituted for the sugar in this recipe. However, using all monk fruit sweetener in the topping results in a harder crust-like topping rather than a loose crumble topping. I prefer to use monk fruit sweetener in the cake and use regular white sugar in the topping. Plant based butter, non-dairy milk and gluten free 1:1 baking flour may be substituted, if needed.
 
Optional Glaze – Mix ¼ cup powdered sugar with 1 teaspoon milk until a thin glaze forms (add more powdered sugar or milk, if needed) and drizzle over cake when ready to serve.
