Warm, Nutty, and Irresistible: The Ultimate Peanut Butter Coffee Cake Recipe You Didn’t Know You Needed

Coffee cake is a timeless comfort, but this peanut butter coffee cake recipe takes it to a whole new level. Rich in protein, naturally sweet, and deeply satisfying, this cake brings together the nutty warmth of peanut butter with the deep character of Vietnamese specialty coffee.

Why Peanut Butter + Coffee Cake Works: The Science of Savor

Nut butters like peanut butter provide mid-palate creaminess and enhance the caramel and chocolatey notes found in medium to dark roast coffees. The oils and proteins in peanuts carry and extend aromatic compounds when baked, especially when paired with coffees high in polyphenols and caramelized sugars. This makes Bazan Coffee’s Vietnamese beans-especially Krong Năng Fine Robusta-an ideal match.

Ingredients (Serves 8–10)

• 1 ½ cups all-purpose flour

• 1 teaspoon baking powder

• ½ teaspoon baking soda

• ¼ teaspoon salt

• ½ cup unsalted butter, softened

• ¾ cup creamy natural peanut butter (unsweetened)

• ¾ cup brown sugar

• 2 large eggs

• ½ cup brewed Bazan Coffee (strong and cooled)

• ½ cup sour cream or Greek yogurt

• 1 teaspoon vanilla extract

Optional Crumble Topping:

• ¼ cup rolled oats

• 2 tablespoons brown sugar

• 2 tablespoons peanut butter

• 1 tablespoon chopped peanuts

Step-by-Step Instructions

Step 1: Brew the Coffee

Use Bazan’s Fine Robusta – Krong Năng for bold flavor or Special Vietnam Blend for smooth, nutty undertones. Brew strong (2x normal ratio) and let it cool.

Step 2: Prepare the Batter

In a bowl, whisk together flour, baking powder, baking soda, and salt. In a separate bowl, cream butter, peanut butter, and brown sugar until fluffy. Beat in eggs one at a time, then add the cooled coffee, sour cream, and vanilla extract.

Gradually mix in the dry ingredients until just combined.

Step 3: Bake It

Pour batter into a greased 8-inch square pan. For the crumble, mix all topping ingredients and sprinkle over the batter. Bake at 350°F (175°C) for 35–40 minutes, or until a toothpick comes out clean.

Step 4: Cool and Serve

Let the cake cool for 15–20 minutes before slicing. Serve with a cup of hot or iced Bazan Coffee for the ultimate pairing.

Why Bazan Coffee is the Best Pairing

Peanut butter demands a coffee with backbone. Bazan Coffee’s Vietnamese beans-grown in mineral-rich Bazan soil-offer the depth and structure to cut through nut oils and sugar. The anaerobic fermentation used in Krong Năng Robusta brings out caramel, cocoa, and honey notes, complementing the savory-sweet nature of peanut butter.

Recommended Pairings:

• Fine Robusta – Krong Năng: Bold, dark, honeyed-perfect with peanut butter

• Special Vietnam Blend: Arabica-Robusta balance, rounded and smooth

• Cau Dat Arabica: Brighter and floral for contrast lovers

Pro Tips for Best Results

• Use natural peanut butter for cleaner flavor and better texture

• Cool coffee before adding to the batter to avoid curdling

• Add dark chocolate chips to the batter for extra richness

• This cake keeps well-store at room temperature for up to 3 days

The New Revolution: Fine Robusta from Vietnam

For years, Robusta has been overshadowed by Arabica, often dismissed as a lower-tier coffee. But Vietnam’s Fine Robusta is changing that perception worldwide.

Through careful cultivation, modern fermentation, and precise processing, Bazan Coffee’s Fine Robusta – Krong Nang represents a new generation of Robusta, bold, complex, and remarkably smooth.

• Thick crema and powerful energy
  With nearly twice the caffeine of Arabica, it produces bold espresso and exceptional cold brew.
