What You’ll Need

• salted butter– For most of my recipes I use salted butter, unsalted works fine too.
• white chocolate chips– Find the white chocolate chips in the baking isle of the grocery store.
• brown sugar– I used light brown sugar for the blondies, dark brown sugar works as well.
• large eggs– For consistency, I use large eggs in all of my cooking and baking.
• pure vanilla extract- Use pure vanilla for best tasting results.
• sour cream– Use full fat sour cream for the recipe.
• all-purpose flour– Flour is the main dry ingredient in the blondies.
• baking soda– Baking soda helps the blondies rise during baking.
• kosher salt– Kosher salt is a coarse salt commonly used in cooking and baking. I prefer it over table salt.
• mini chocolate chips– If you can’t find mini chocolate chips, regular are fine too.
• creamy peanut butter– Any favorite brand of peanut butter is fine.

How To Make Blondies

1. Preheat oven to 350 degrees F. and line an 8×8 inch baking dish with parchment paper.
2. Melt butter in microwave safe bowl until hot. Stir in ¾ Cup white chips until melted and smooth. In a large bow whisk the eggs and sour cream and vanilla until well combined then add the brown sugar, stirring until well combined.
3. Add the flour, baking powder, salt, and baking soda until dough forms.
4. Stir in melted white chips/butter mixture then add white and chocolate chips.
5. Pour blondie batter into baking dish, spreading evenly.
6. Spoon dollops of creamy peanut butter over top of batter then take a knife to run peanut butter through batter, making swirls as you go. Top with more chocolate chips.
7. Bake for 30-35 minutes, or until cooked through and just starting to turn golden around the edges. Let cool completely before digging in!

Start with a large mixing bowl and combine the wet ingredients.

Add dry ingredients along with the melted butter/white chocolate chip mixture.

Add more white chocolate chips and mini chocolate chips.

Stir to combine. This dough is so unbelievably delicious.

Place dollops of creamy peanut butter evenly on top of blondie dough.

Take a knife and and swirl peanut butter into blondies. Bake for 30-35 minutes, or until center is set. Remove from oven and let cool before cutting into squares.

Cut bars into squares and serve room temperature or slightly warmed.

Serve blondies either room temperature or try serving warm with a scoop of vanilla ice cream on top.
