How to Make Low-Sugar Blueberry Protein Muffins with Sourdough Discard

Step 1: Preheat the Oven

Preheat your oven to 350° F to ensure it’s hot enough when your muffins go in.

Step 2: Prepare the Muffin Tin

Line a muffin tin with paper liners. This will prevent sticking and make cleanup easier.

Step 3: Mash the Blueberries

Using a fork, lightly mash the blueberries in a bowl. This will help release their juices during baking.

Step 4: Combine Dry Ingredients

In a medium-large mixing bowl, combine all dry ingredients:
1. Add flour.

3. Mix in brown sugar, baking soda, baking powder, salt, and mashed blueberries.

2. Add vanilla extract and whole milk.
3. Crack in eggs and whisk until everything is blended smoothly.

Step 6: Combine Mixtures

Gently fold the wet ingredients into the dry mixture until just combined. Avoid over-mixing; it’s okay if there are clumps!

Step 7: Spoon Batter into Muffin Tins

Spoon the batter into prepared muffin tins. For extra flavor, top each muffin with additional blueberries if desired.

Step 8: Bake Muffins

Bake in the preheated oven for about 30 minutes total. Rotate the pan halfway through for even cooking.

Step 9: Cool Down

Once baked, allow cooling for about 15 minutes before serving or storing. Enjoy your delightful muffins!

Common Mistakes to Avoid

Baking can be tricky, especially when making Low-Sugar Blueberry Protein Muffins with Sourdough Discard. Here are some common mistakes to avoid:

  • Skipping the Room Temperature Ingredients: Using cold butter, eggs, or milk can lead to uneven mixing. Always bring these ingredients to room temperature for better results.

  • Not Measuring Ingredients Accurately: Incorrect measurements can alter the texture and flavor. Use proper measuring cups and spoons for accuracy.
  • Ignoring Temperature Settings: Baking at the wrong temperature can lead to undercooked or burnt muffins. Preheat your oven and check with an oven thermometer if necessary.
  • Using Old or Expired Ingredients: Fresh ingredients yield the best results. Check expiration dates on your flour and baking powder before starting.
