Tender coffee-infused bars with buttery crumb topping and rich coffee flavor are perfect for breakfast or an afternoon treat. These bars deliver a delightful balance of sweetness, texture, and aroma for any dessert lover.

I first baked these Coffee Butter Streusel Bars for an early morning get-together with friends. The aroma alone had everyone asking for the recipe before the bars even cooled!

Ingredients

  • All-purpose flour (for streusel and base): Adds structure and tenderness to the bars and crumb topping
  • Light brown sugar: Provides moisture and a deep caramel flavor to the streusel
  • Unsalted butter: Adds richness and helps create a tender crumb for both layers
  • Ground cinnamon: Infuses warmth and spice into the topping
  • Fine sea salt: Balances sweetness and enhances flavors
  • Baking powder: Leavens the bar base for a soft texture
  • Granulated sugar: Sweetens the coffee bar base
  • Large egg: Binds ingredients and adds structure
  • Pure vanilla extract: Adds aromatic flavor to the base
  • Strong brewed coffee: Gives the bars their signature flavor; also used in the glaze
  • Powdered sugar (optional glaze): Adds a touch of sweetness to finish the bars

Instructions

Prep Pan and Oven:
Preheat oven to 350°F (175°C). Line an 8x8-inch (20x20 cm) baking pan with parchment paper, leaving overhang for easy removal.
Make Streusel:
In a medium bowl, combine flour, brown sugar, cinnamon, and salt. Add cold butter cubes and cut in with a pastry cutter or fingers until mixture resembles coarse crumbs. Refrigerate until ready to use.
Prepare Base:
In a small bowl, whisk flour, baking powder, and salt. In a large bowl, cream together softened butter and granulated sugar until light and fluffy. Beat in the egg, vanilla, and brewed coffee until combined.
Combine Wet and Dry:
Gradually add the dry ingredients to the wet mixture, mixing just until incorporated. Spread batter evenly into the prepared pan.
Add Streusel:
Sprinkle the chilled streusel mixture evenly over the batter.
Bake:
Bake for 30–35 minutes, or until the top is golden and a toothpick inserted into the center comes out clean.
Cool & Glaze:
Cool completely in the pan. For the glaze, whisk powdered sugar and brewed coffee until smooth, then drizzle over cooled bars.
Slice & Serve:
Lift bars from the pan using parchment paper and cut into 12 squares.
