Equipment
- kitchen scale optional but recommended
- mixing bowls
- jumbo muffin tin
- jumbo muffin liners
- rubber spatula
Ingredients
- 1 White Super Moist Cake Mix 14oz
- ¾ cup kefir plain room temperature
- ½ cup vegetable oil
- 3 large eggs room temperature
- 1 ½ cup blueberries fresh or frozen
Streusel Topping
- ¼ cup all-purpose flour
- 2 tbsp sugar
- 2 tbsp brown sugar light or dark
- 3 tbsp old fashioned oats
- pinch fine sea salt
Instructions
- Preheat oven to 425 F. Empty cake mix contents into a medium bowl.
- Add kefir, vegetable oil, and eggs and mix on medium-high until well combined. Scrape down the bowl.
- Add blueberries and use a rubber spatula to fold into the batter. Fold in until just evenly distributed.
- Place muffin cups into muffin pan. Use a cookie scoop to scoop batter and fill the muffin cavity ¾ full.
- In a separate small bowl, combine all ingredients except cold butter and mix thoroughly.
- Add cold butter to the streusel mix and use a pastry cutter, fork, or fingers to help combine the butter into the dry ingredients.
- Add a thin layer of the streusel mix to the top of the muffin batter. Lightly pat the streusel onto the batter to ensure it helps stick while baking.
- Bake at 425 F for 6 minutes. Then reduce the oven temperature to 375 F but DO NOT open the oven door. Bake an additional 22 - 24 minutes, or until muffin tops are golden brown.
- Remove from oven and place on a wire rack to cool.
Notes
Kitchen scale is recommended. While I do share the volume measurements, I always recommend a kitchen scale.
Measuring Dry Ingredients should always be done using the spoon and level method if you are not using a kitchen scale.
Room Temperature Ingredients. I recommend the kefir and large eggs to be at room temperature to help the ingredients mix easily.
Do not fill to the brim because this will cause the batter to flood over and create wonky-looking muffins!
Baking initially at a high temperature will help your muffins quickly rise to create a beautiful dome. Lowering the temperature soon after will allow for an even distribution of baking.
