5 Reasons Why You Need This Coffee Cake in your life
- It's easy to make!
- The coffee cake is light and fluffy, with flavors of vanilla and almond in each bite. So good!
- The homemade blueberry pie filling's fresh taste and texture are wonderful, thanks to the beautifully plump blueberries! And nothing beats the smell of blueberries in the oven!
- Adding the drizzled simple glaze to the top brings all the flavors together nicely!
- It's really, REALLY good served warm!
Coffee cakes, in general, to me are just a great treat to make for when company is coming over or if you have family in town for the weekend!
How to Make the Recipe
Let's do a quick run-through on how to make this super easy blueberry swirl coffee cake recipe.
Whisk the dry ingredients. This includes all-purpose flour and baking powder.
Beat the wet ingredients next. Start with the unsalted butter and vegetable shortening. Then add the granulated sugar, vanilla extract, almond extract, and finally, the eggs.
Combine the dry and wet together. The final step is to gradually add in the whisked dry ingredients with the wet, mixing together until just combined. Do not over-mix the cake batter.
Alternate between the batter and filling. Using a spoon, add ⅔ of the coffee cake batter to the bottom of the prepared 13-inch x 9-inch pan. Then add all of the homemade blueberry pie filling. The final step is adding the remaining coffee cake batter by the spoonful over the top.
Bake the blueberry swirl coffee cake. Bake for 40-45 minutes at 350ºF or until the top of the coffee cake is a nice light golden brown.
Make the glaze. While the coffee cake begins to cool, whisk together the powdered sugar and milk. You can use any dairy type of milk. I used 1%. Immediately drizzle it over the top of the coffee cake and serve!
Homemade Blueberry Pie Filling
I absolutely love making pie fillings! Ever since I made my Homemade Cherry Pie, I've been hooked! This blueberry pie filling recipe requires only five ingredients, isn't overly sweet, and takes roughly 15 minutes to make. The only hard part is waiting for it to cool down!
Blanch the blueberries. An important step that should not be skipped. After this is done, drain the blueberries and keep them warm in a bowl covered with a towel.
Make the filling. It takes roughly 7-8 minutes to see the sugar fully dissolve and the clear jel to thicken into the filling.
Add in the blanched blueberries. Once done, remove the pan from the heat, and add in the blanched blueberries. Stir it all together, then spoon it into a large bowl (preferably glass) to cool completely. It takes anywhere from 2-3 hours to cool the pie filling down.
Why Do You Blanch Blueberries Before Adding Them to the Pie Filling?
I just need to mention first that blanching the blueberries does not mean you are cooking them. Blanching is boiling the fruit at a high temperature to stop the enzymes from causing the flavors to break down.
How Long Will This Homemade Blueberry Pie Filling Keep?
If kept in a tightly sealed container, this homemade blueberry pie filling will last up to a week in the refrigerator. If you're into canning, you can can this pie filling as well!
What Baking Tools Are Needed?
For the homemade blueberry pie filling, you'll need:
- Large saute pan or sauce pan
- Slotted spoon or colander
- Medium-size bowl
- Clean, kitchen towel
For the coffee cake, you'll need:
- 13-inch x 9-inch baking pan. I love using my Nordic Ware pan because it also has a lid.
- Flour-based baking spray. I will forever swear by Baker's Joy!
- Hand mixer or stand mixer fitted with a paddle attachment
- Whisk, spatula, and spoon
For the simple glaze, you'll need:
- Medium-size bowl
You will need a 13 inch x 9 inch baking pan.
Mix 1 cup (or 120 grams) of powdered sugar with 2-3 tablespoons of milk, then whisk together. Pour over the top of the warm coffee cake.
Yes, absolutely! You can even try a cherry, peach, or raspberry pie filling in instead too. Store-bought pie fillings are typically in 21 ounce cans. You can choose to use just 1, 21 ounce can for this recipe, or—for a little extra filling—you can buy two cans and use ¼ cup of the second can.
The best way is to keep it stored in a tightly sealed container in the refrigerator. The blueberry pie filling will last up to one week. If you're into canning, you can can this pie filling instead.
This coffee cake recipe yields approximately 12 slices or squares. You can cut them smaller, if you prefer.
To cool completely, which is best for this recipe, will take 2-3 hours.
Yes. It's important to do this step because it will stop the enzymes from causing the flavors to break down.
No they are not the same thing and should not be used as a substitute for this recipe. Clear Jel has little to no after taste compared to other corn starches, and does a great job of thickening the pie filling and keeping the juices clear. If you plan to use this recipe for canning, the USDA recommends using this over other thickeners.
