Ingredients You’ll Need
(Serves 12 | Prep Time: 10 minutes | Cook Time: 25 minutes | Total Time: 35 minutes)
- 1 cup creamy peanut butter
- 1 cup brown sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1 cup chopped strawberries
- 1/2 cup M&M candies (or chocolate chips if you prefer)
How to Make M&M Strawberry Peanut Butter Blondies
1. Preheat the Oven
Set your oven to 350°F (175°C) and grease a 9×9-inch baking pan or line it with parchment paper for easy removal.
2. Mix Peanut Butter and Sugar
In a large bowl, combine the creamy peanut butter and brown sugar. Stir until smooth and well blended — this forms the rich, sweet base of your blondies.
3. Add Eggs and Vanilla
Crack in the eggs and add the vanilla extract. Stir until everything is combined into a smooth, glossy batter.
4. Add Dry Ingredients
Sprinkle in the all-purpose flour, baking powder, and salt. Stir gently until just combined — don’t overmix or the blondies can turn out dense.
5. Fold in Strawberries and M&Ms
Carefully fold in the chopped strawberries and M&M candies. The pops of color and fruity sweetness make these blondies really stand out.
6. Pour into the Pan
Spread the batter evenly into the prepared baking pan. Use a spatula to smooth the top.
7. Bake
Place the pan in the oven and bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
8. Cool and Cut
Let the blondies cool in the pan for 10 minutes, then carefully lift them out and cut into squares.
9. Serve and Enjoy
These blondies are delicious warm, but I also love them at room temperature with a glass of cold milk or a cup of coffee.
Tips for the Best Peanut Butter Blondies
- Use room-temperature ingredients for the smoothest batter.
- Pat strawberries dry after chopping to prevent excess moisture in the blondies.
- Swap M&Ms for chocolate chips or peanut butter chips if desired.
- Let them cool slightly before slicing to help them hold their shape.
- Store leftovers in an airtight container for up to 3 days — if they last that long!
Fun Variations to Try
- Add crushed pretzels for a salty crunch.
- Use white chocolate chips for an extra-sweet twist.
- Add a swirl of strawberry jam before baking for more berry flavor.
- Top with a drizzle of melted chocolate for a bakery-style finish.
