The BEST Quick & Easy Moist Blueberry Muffins
If you haven’t discovered the many things you can make with boxed cake mix besides cake, you’re in for a treat. These moist blueberry muffins are incredibly simple, made with just a few everyday ingredients. They’re perfect for breakfast, a mid-day snack, or an after-school treat — even picky eaters tend to gobble them up.
Muffins are my go-to for busy mornings and quick snacks. They bake fast, store well, and travel easily for lunches, sports practice, or road trips. Make a batch on the weekend and you’ll have a convenient grab-and-go option all week.

Easy Cake Mix Blueberry Muffins
- 1 box yellow, white, or lemon cake mix
- 2 tbsp flour
- 1 tsp baking powder
- 3 eggs
- 2/3 cup milk
- 1/3 cup vegetable oil
- 2 cups fresh or frozen blueberries (note: frozen berries can turn the batter purple)

Combine all ingredients except the blueberries and mix until smooth. Gently fold in the blueberries, reserving a few to press on top of each muffin for a pretty finish. Spoon the batter into a prepared muffin tin and bake at 375°F for 15–20 minutes, or until a toothpick inserted in the center comes out clean.
Helpful Tips
- To help prevent berries from sinking, toss them with a tablespoon of flour before folding into the batter.
- This base works with lots of mix-ins: diced strawberries, bananas, chopped nuts, chocolate chips, cinnamon, or raisins all work well.

Quick & Easy Moist Blueberry Muffins (Made With Cake Mix)
Ingredients
- 1 box yellow, white, or lemon cake mix
- 2 tbsp flour
- 1 tsp baking powder
- 3 eggs
- 2/3 cup milk
- 1/3 cup vegetable oil
- 2 cups fresh or frozen blueberries *see notes
Instructions
-
Preheat oven to 375°F and line a muffin pan with paper cups or grease the pan well.
-
In a large bowl, combine the cake mix, flour, baking powder, eggs, milk, and oil. Stir until evenly mixed.
-
Gently fold in the blueberries, saving a few to place on top of each muffin if desired.
-
Spoon the batter into the prepared muffin cups, filling them nearly to the top.
-
Bake 15–20 minutes, or until a toothpick inserted in the center comes out clean. Cool slightly before serving.
Notes
- Fresh blueberries usually give the best texture and appearance. Frozen berries can discolor the batter and are more likely to sink.
- To keep berries from sinking, toss them with a tablespoon of the dry mix before folding into the batter. Setting a few berries on top of each muffin right before baking also helps.
