Ingredients

• ½ cup vegetable oil

How to Make Cake Mix Blueberry Muffins

Step 1: Prepare the Oven

Preheat your oven to 350°F (175°C).

Line a 12-cup muffin pan with paper liners or lightly grease each cup.

Step 2: Mix the Batter

In a large mixing bowl, combine:

• Yellow cake mix
• Eggs
• Vegetable oil
• Milk
• Vanilla extract

Mix until smooth and well combined. Do not overmix.

Step 3: Add the Blueberries

Toss the blueberries with the tablespoon of flour to help prevent them from sinking.

Gently fold the blueberries into the batter using a rubber spatula.

Step 4: Fill the Muffin Cups

Divide the batter evenly among the prepared muffin cups, filling each about ¾ full.

Sprinkle the tops with coarse sugar if desired.

Step 5: Bake

Bake for 18–22 minutes, or until the tops are lightly golden and a toothpick inserted into the center comes out clean.

Step 6: Cool and Serve

Allow the muffins to cool in the pan for about 5 minutes.

Transfer to a wire rack to cool completely or enjoy warm with butter.

Tips for Perfect Muffins

• Coat blueberries in flour to keep them evenly distributed.
• Do not overmix the batter.
• Use room-temperature eggs for a smoother batter.
• Fill muffin cups evenly for uniform baking.
• Fresh blueberries give the best texture, but frozen berries work well too.

Frequently Asked Questions

Can I use frozen blueberries?

Yes. Add them directly from the freezer without thawing to prevent excess moisture and color bleeding.

Can I use white cake mix?

Absolutely. White, yellow, vanilla, or butter cake mix all work well.

Why coat the blueberries in flour?

A light coating of flour helps suspend the berries in the batter so they don’t sink to the bottom during baking.

Can I make mini muffins?

Yes. Bake mini muffins for 10–12 minutes.

Can I add a crumb topping?

Definitely! A simple mixture of butter, flour, brown sugar, and cinnamon creates a delicious bakery-style streusel.

How do I know when they’re done?

Insert a toothpick into the center of a muffin. If it comes out clean or with a few moist crumbs, they’re ready.
