Ingredients Notes
Here are a few key ingredients needed for this blueberry breakfast cake.
Butter - This will be softened.
Eggs – Make sure they’re at room temperature before beginning.
Flour – All-purpose flour is used in this recipe.
Lemon – Both lemon zest and lemon juice are used in this recipe.
Blueberries – Make sure to use fresh, and not frozen. Frozen berries hold a lot more liquid, therefore making the batter runnier and affecting the entire bake.
Yogurt - You can also substitute this for kefir or buttermilk. To make 1/2 cup of buttermilk, stir 1/2 cup of milk with 1/2 tbsp of lemon juice or vinegar. Allow to sit on your counter for at least 10 minutes before using.
Step by step instructions
Here is how to make and bake these blueberry breakfast cake. You will need a 9x9 baking pan lined with parchment paper, 3 mixing bowls, a spatula, and an electric handheld mixer.
Step 1 – Prep. For easy removal of the cake, place parchment paper on the bottom and 2 sides of the pan. Lightly grease the other two sides and then set aside.
Step 2 - Mix dry ingredients. In a medium sized bowl, add in flour, baking powder, and salt. Stir to combine and set aside.
Step 3 - Cream the butter and sugar. In a large bowl, add softened butter, white sugar, and lemon zest. Beat with an electric mixer on medium speed for 2-3 minutes until it's light and fluffy. Make sure to scrap the sides of the bowl.
Step 4 - Add in wet ingredients. Add in the egg, egg yolk, vanilla, yogurt, and lemon juice. Continue mixing on medium speed until smooth.
Step 5 - Add in dry ingredients. Combine the dry and wet ingredients until a soft batter forms. Do not over-mix!
Step 6 – Add blueberries. Gently toss the blueberries in 1-2 tsps of flour before adding them into the mixing bowl. This will help absorb any liquid they may have from washing. Then add into the bowl and mix in a few times.
Step 7 - Bake. Spread the batter into the prepared pan evenly and sprinkle extra white sugar on top. This will give you a sweet crunchy top.
Bake for 35-45 minutes. After 30 minutes I would start checking with a toothpick to see if it's ready. A toothpick should come out clean.
