Moist muffins combining creamy peanut butter with sweet guava preserves for a nostalgic PB&J-inspired treat.

# What You'll Need:

→ Dry Ingredients

01 - 2 cups all-purpose flour
02 - 1 teaspoon baking powder
03 - 1/2 teaspoon baking soda
04 - 1/4 teaspoon salt

→ Wet Ingredients

05 - 1/2 cup creamy peanut butter
06 - 1/2 cup unsalted butter, melted and cooled
07 - 1 cup granulated sugar
08 - 2 large eggs
09 - 1 cup whole milk
10 - 1 teaspoon vanilla extract

→ Filling and Topping

11 - 2/3 cup guava preserves or guava jelly
12 - 1/4 cup roasted peanuts, chopped

# Steps:

01 - Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners or lightly grease with butter.
02 - In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
03 - In a large bowl, beat together peanut butter, melted butter, and sugar until smooth and creamy.
04 - Add eggs one at a time, mixing well after each. Stir in milk and vanilla extract until fully incorporated.
05 - Gradually fold the dry ingredients into the wet mixture until just combined. Do not overmix.
06 - Fill each muffin cup halfway with batter. Add 1 generous teaspoon of guava preserves to the center of each.
07 - Spoon remaining batter over the preserves to cover completely.
08 - Sprinkle chopped peanuts on top of each muffin.
09 - Bake for 20 to 22 minutes, or until a toothpick inserted into the edge comes out clean.
10 - Cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

# Expert Insights:

01 -
  • They hit that sweet spot between indulgent and light, so you don't feel guilty grabbing seconds.
  • The guava surprise inside keeps each bite interesting and makes them feel more special than a standard muffin.
  • They actually stay moist for days, which means less stress about stale baked goods.
02 -
  • Never—and I mean never—skip the cooling step on the wire rack, or they'll steam themselves into a dense, gummy mess at the bottom.
  • The guava preserves make all the difference between a good muffin and one that tastes like something special, so don't cheap out or use jelly if preserves are available.
03 -
  • Room temperature eggs and milk blend more smoothly into the peanut butter mixture, creating a silkier batter that results in tender muffins.
  • Always insert the toothpick into the edge or top of the muffin, never through the guava center, because the jam will always look wet and might trick you into overbaking.
