What Exactly is a Blondie?

Before we dive in, let’s talk about the amazing base for our Peanut Butter Blondie Ice Cream Sandwiches. A blondie is essentially a brownie without the cocoa. Instead of a deep chocolate flavor, its primary notes are vanilla, butterscotch, and brown sugar. The secret to a great blondie is its texture: it should be dense and chewy, never light or cakey. This is often achieved by using melted butter instead of creamed butter, which is exactly what we do in this recipe. This sturdy, chewy texture makes it the absolute perfect choice for an ice cream sandwich.

The Key Ingredients for Your Comfort Dessert

Each component in these Peanut Butter Blondie Ice Cream Sandwiches is chosen to maximize flavor and create the perfect chewy, creamy texture.

• The Peanut Butter Blondies:
  • Melted Unsalted Butter: Using melted butter is the key to a dense, chewy blondie.
  • Brown & Granulated Sugar: The combination provides moisture, sweetness, and that signature butterscotch flavor.
  • Room Temperature Peanut Butter: Using smooth, room-temperature peanut butter allows it to mix seamlessly into the batter and makes it easy to drizzle and swirl into the ice cream.
  • Eggs & Vanilla: For richness, binding, and classic flavor.
  • Flour, Cinnamon, Salt, Baking Powder: The dry ingredients provide the structure. A hint of cinnamon beautifully complements the peanut butter.
• The Ice Cream Filling:
  • Vanilla Ice Cream: A high-quality vanilla ice cream is the perfect creamy, neutral canvas for the double dose of peanut butter in this recipe for Peanut Butter Blondie Ice Cream Sandwiches.

Step-by-Step Guide to Your Blondie Masterpiece

This recipe involves baking the blondies, then assembling and freezing the final sandwiches. Following the cooling and freezing times is crucial for a neat, sliceable result.

Part 1: Bake the Peanut Butter Blondies

1. Prepare Your Pans: Preheat your oven to 350°F. Grease two 8-inch square baking dishes with nonstick cooking spray. Line them with parchment paper, leaving about a 1-inch overhang or “wing” on two opposite sides. These wings are essential for lifting the blondies out of the pans later.
2. Mix the Dry Ingredients: In a large bowl, whisk together the flour, brown sugar, granulated sugar, cinnamon, salt, and baking powder. Breaking up any clumps of brown sugar now is key.
3. Mix the Wet Ingredients: In a separate medium bowl, whisk together the melted butter, vanilla extract, eggs, and 3/4 cup of the room-temperature peanut butter until smooth.
4. Combine and Bake: Pour the wet ingredients into the dry ingredients. Use a wooden spoon or a spatula to stir everything together until just combined. Do not overmix. Divide this batter evenly between your two prepared baking dishes and spread it out in a smooth layer.
5. Bake and Cool Completely: Bake the blondies for 23-28 minutes, or until the centers are just set and a toothpick inserted comes out with moist crumbs, not wet batter. It is crucial to let the blondies cool completely in their pans on a wire rack. Adding ice cream to even a slightly warm blondie will result in a melted mess.

Part 2: Assemble and Freeze Your Ice Cream Sandwiches

1. Prepare the Ice Cream: While the blondies cool, let your 2 pints of vanilla ice cream soften at room temperature until they are easy to spread.
2. Assemble the Layers: Once the blondies are completely cool, you are ready to build your giant Peanut Butter Blondie Ice Cream Sandwich. Spread the softened ice cream in an even layer over one of the blondies (while it’s still in its pan).
3. Add the Peanut Butter Swirl: Drizzle the remaining 1/2 cup of peanut butter over the top of the ice cream. Use an offset spatula or a butter knife to gently swirl the peanut butter into the ice cream, creating beautiful ribbons of flavor.
4. Top and Freeze: Carefully lift the second blondie out of its pan using the parchment wings and place it on top of the ice cream layer. Gently press down.
5. Freeze Until Solid: Cover the pan with plastic wrap and place it in the freezer until the ice cream is completely firm, which will take about 4 hours, or preferably overnight. This long freeze is essential for getting clean cuts.

Part 3: Slice and Serve

1. Unmold and Slice: Using the parchment wings, lift the entire frozen blondie block out of the pan and onto a cutting board. Use a large, sharp knife to trim the edges for a neat look if you desire.
2. Cut into Squares: Cut the block into 1 1/2- to 2-inch squares to create your individual Peanut Butter Blondie Ice Cream Sandwiches. For the cleanest cuts, run your knife under hot water and wipe it dry between each slice.
3. Store and Enjoy: Wrap the individual sandwiches in plastic wrap or place them in an airtight container and store them in the freezer until ready to serve.
