Espresso Chocolate Chip Blondies with Brown Sugar Frosting Cooking Guide

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your blondies bake evenly.
Step 2: Prepare the Baking Pan
Grease an 8×8 inch baking pan or line it with parchment paper for easy removal.
Step 3: Mix the Wet Ingredients
In a large mixing bowl, whisk together the melted unsalted butter, light brown sugar, and vanilla extract until well combined. Add in the egg and whisk until the mixture is smooth.
Step 4: Add the Espresso
Stir in the instant espresso granules into the wet mixture, ensuring they are fully dissolved.
Step 5: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour and salt. Gradually add this to the wet mixture, stirring until just combined.
Step 6: Fold in the Chocolate Chips
Gently fold in the semi-sweet chocolate chips, mixing until they are evenly distributed throughout the batter.
Step 7: Bake the Blondies
Pour the batter into the prepared baking pan, spreading it evenly. Bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean with a few moist crumbs.
Step 8: Cool the Blondies
Once baked, remove the blondies from the oven and let them cool in the pan for about 10 minutes. Then, transfer them to a cooling rack to cool completely.
Step 9: Make the Brown Sugar Frosting
In a mixing bowl, beat together the softened unsalted butter and light brown sugar until creamy. Add the vanilla extract and a pinch of salt, mixing until smooth. Gradually add in powdered sugar until the frosting reaches your desired consistency.
Step 10: Frost the Blondies
Once the blondies are completely cooled, spread the brown sugar frosting evenly over the top. Cut into squares and serve!
How to Make It Lighter

- Substitute half of the butter with unsweetened applesauce for a lower-fat version.
- Use a sugar substitute in place of brown sugar if desired.
- Replace the semi-sweet chocolate chips with dark chocolate chips for a richer flavor with less sugar.
- Consider using whole wheat flour for added fiber and nutrients.
Slip-Ups to Skip
- Don’t overmix the batter after adding the flour; this can lead to dense blondies.
- Make sure not to skip the cooling step before frosting; warm blondies will melt the frosting.
- Check your oven’s temperature; an oven that runs hot can overbake the blondies.
- Using fresh espresso granules is key; stale granules can result in a lack of flavor.

If you want to prep ahead, these Espresso Chocolate Chip Blondies with Brown Sugar Frosting freeze beautifully! Simply wrap individual squares in plastic wrap and place them in an airtight container.

Your Questions, Answered
Can I use decaf espresso granules?
Absolutely! Decaf espresso granules will work just as well if you want to enjoy the flavor without the caffeine kick.
How should I store these blondies?
Store them in an airtight container at room temperature for up to a week. If frosted, keep them refrigerated to maintain the frosting’s texture.
Can I add nuts to the recipe?
Yes, feel free to fold in some chopped nuts like walnuts or pecans for added texture and flavor!
What if I don’t have instant espresso granules?
