Ingredients for the Best Peanut Butter Caramel Blondies Recipe

• 6 tablespoons unsalted butter, melted – Melted butter gives these chewy blondies their rich, buttery texture and helps create soft centers with slightly crisp edges.
• 3/4 cup packed light or dark brown sugar – Brown sugar adds moisture and a deep caramel-like sweetness that makes these peanut butter dessert bars extra flavorful.
• 2 teaspoons vanilla extract – Vanilla enhances the peanut butter and caramel flavors while adding warmth to every bite.
• 1 large egg, room temperature – A room-temperature egg mixes more easily into the batter and helps create tender, chewy blondie bars.
• 1/4 teaspoon salt – A little salt balances the sweetness and brings out the rich peanut butter flavor.
• 1/3 cup creamy peanut butter – Use a smooth, no-stir peanut butter for the best texture. It blends evenly into the batter and keeps the blondies soft and moist.
• 3/4 cup all-purpose flour – Flour provides structure while keeping these homemade blondies tender and perfectly chewy.
• 1 cup mini Rolo candies (or chopped regular Rolos) – These add pockets of gooey caramel throughout the blondies, making every bite rich and delicious.
• Caramel sauce, for drizzling (optional) – A warm drizzle of caramel sauce adds an extra layer of sweetness and makes these easy peanut butter caramel blondies even more irresistible.
• Vanilla ice cream, for serving (optional) – Serve a warm blondie with a scoop of vanilla ice cream for a classic bakery-style dessert.

How to Make the Best Peanut Butter Caramel Blondies

Step 1: Prepare the Baking Pan

Preheat your oven to 350°F (175°C). Line an 8-inch square baking pan with parchment paper, leaving an overhang on two sides. This makes it easy to lift the blondies out of the pan for clean slicing.

Step 2: Mix the Wet Ingredients

In a large microwave-safe bowl, melt 6 tablespoons of unsalted butter and let it cool for about a minute. Whisk in the brown sugar and vanilla extract until smooth, then add the room-temperature egg and whisk until the mixture becomes lighter and glossy. Finally, stir in the creamy peanut butter and salt until fully combined.

Step 3: Add the Dry Ingredients

Gently fold the all-purpose flour into the wet mixture using a spatula. Mix just until no dry streaks remain. Overmixing can make the blondies dense instead of soft and chewy, so stir only until everything is incorporated.

Step 4: Fold in the Caramel

Add about three-quarters of the mini Rolo candies to the batter and gently fold them in. Spread the batter evenly into the prepared pan, then press the remaining Rolos over the top so every bite is filled with gooey caramel.

Step 5: Bake Until Golden

Bake the peanut butter caramel blondies for 20–22 minutes on the center oven rack. The edges should look set while the center remains slightly soft. The blondies will continue to firm up as they cool, giving them their perfect chewy texture.

Step 6: Cool and Serve

Let the blondies cool in the pan for at least 15 minutes before lifting them out with the parchment paper. Slice into squares and serve as they are, or drizzle with warm caramel sauce and enjoy with a scoop of vanilla ice cream for an extra-special homemade dessert.

Expert Tips for the Best Peanut Butter Caramel Blondies

Use Room-Temperature Ingredients

Let the egg sit at room temperature for about 10–15 minutes before mixing. A room-temperature egg combines more easily with the melted butter, creating a smooth batter and helping the blondies bake evenly.

Don’t Overmix the Batter

After adding the all-purpose flour, gently fold the batter just until no dry streaks remain. Overmixing can develop too much gluten, making the blondies firm instead of soft, buttery, and chewy.

Bake in a Metal Pan

For the best results, use a light-colored metal baking pan instead of glass. Metal distributes heat more evenly, giving you golden edges, a perfectly baked center, and that classic bakery-style blondie texture.

Don’t Overbake

Keep an eye on the oven during the last few minutes of baking. The edges should look set while the center remains slightly soft. The blondies will continue to firm up as they cool, giving them their signature chewy texture without drying out.

Cool Before Slicing

Allow the blondies to cool in the pan for at least 15 minutes before lifting them out and cutting into squares. This gives the gooey caramel time to set slightly, making the bars easier to slice while still staying soft and delicious.

Finish with Extra Caramel

For an extra indulgent dessert, press a few additional Rolo candies on top before baking and drizzle the cooled blondies with warm caramel sauce before serving. Pair them with a scoop of vanilla ice cream for a rich homemade dessert that’s perfect for parties, holidays, or weekend baking.

Ingredient Substitutions for Peanut Butter Caramel Blondies

Mini Rolos

If you don’t have mini Rolos, use 1 cup chopped full-size Rolos instead. They’ll melt into delicious pockets of caramel and give the blondie bars a slightly chunkier texture.

All-Purpose Flour

Replace the all-purpose flour with an equal amount of a 1:1 gluten-free baking flour blend. This keeps the homemade blondies tender while making them suitable for a gluten-free diet.

Unsalted Butter

Plant-based stick butter works well as a substitute for unsalted butter. It creates a similar soft, buttery texture while making the recipe dairy-free if paired with dairy-free caramel candies.

Creamy Peanut Butter

Swap the creamy peanut butter for smooth almond butter or sunflower seed butter if preferred. The blondies will still be chewy and delicious, although the flavor will be slightly different.

Brown Sugar

Light and dark brown sugar can be used interchangeably in this peanut butter caramel blondies recipe. Dark brown sugar creates a deeper caramel flavor, while light brown sugar produces a lighter, buttery sweetness.

How to Store Peanut Butter Caramel Blondies

Room Temperature

Store the blondies in an airtight container at room temperature for up to 3 days. Keep them in a cool, dry place to maintain their soft texture and rich peanut butter flavor.

Refrigerator

For longer storage, refrigerate the blondie bars in a sealed airtight container for up to 1 week. The caramel will become firmer when chilled, so let the blondies sit at room temperature for 10–15 minutes before serving for the best texture.

Freezer

Wrap each blondie individually in plastic wrap, then place them in a freezer-safe bag or airtight container. Freeze for up to 3 months. This is a great option for making these easy peanut butter dessert bars ahead of time.

Reheating

Thaw frozen blondies at room temperature for about 1 hour. For a warm, gooey dessert, microwave one blondie for 15–20 seconds and drizzle with caramel sauce or serve with a scoop of vanilla ice cream.
