- Total Time: 40 minutes
Ingredients
For the Main Dish:
- 1 1/2 cups all-purpose flour
- 1 cup granulated sugar
- 1/4 cup unsweetened cocoa powder
- 1 tsp baking soda
- 1/2 tsp salt
- 1 cup water
- 1/3 cup vegetable oil
- 1 tbsp white vinegar
- 1 tsp vanilla extract
- 1/2 cup creamy peanut butter
How I Make It
Step 1:
Start by preheating your oven to 350°F and lightly greasing an 8×8-inch baking pan. In the pan itself (yes, no extra bowls!), whisk together the flour, sugar, cocoa powder, baking soda, and salt until evenly combined. This keeps cleanup super easy.
Step 2:
Pour in the water, vegetable oil, vinegar, and vanilla directly into the dry ingredients. Using a spatula or wooden spoon, stir everything together just until combined. The batter will be smooth and a bit glossy—perfect for that dense, fudgy texture.
Step 3:
Now, dollop the peanut butter all over the top of the batter. Using a butter knife or a skewer, gently swirl it into the batter—don’t overmix; you want visible peanut butter streaks.
Step 4:
Pop the pan into the oven and bake for about 28-30 minutes. You’ll know it’s done when a toothpick inserted in the center comes out with few moist crumbs but not wet batter. The cake should look set and smell like warm chocolate heaven.
Step 5:
Let it cool in the pan for at least 15 minutes—this helps it firm up for cleaner slices and keeps the peanut butter from sliding off.
Step 6:
Slice it up and serve warm for that melty peanut butter sensation, or at room temp for a fudgy, rich treat that sticks to your ribs.
Variations & Tips
- Swap creamy peanut butter for crunchy to add a nutty texture.
- Add a pinch of instant coffee powder to deepen the chocolate flavor.
- Try swirling in a few tablespoons of Nutella or almond butter instead.
- Top with a sprinkle of flaky sea salt to balance the sweetness.
- For a gluten-free version, substitute all-purpose flour with a 1:1 gluten-free flour blend.
- If you want more peanut butter, drizzle some on top as soon as the cake comes out of the oven.
How I Like to Serve It
This cake is absolutely perfect on a cozy weekend afternoon with a cold glass of milk or a piping hot cup of coffee. I love serving it as an easy dessert at casual gatherings—watch it disappear in no time! And if you’re feeling fancy, a scoop of vanilla ice cream or a dollop of whipped cream on the side makes it downright irresistible.
Notes
- Store leftovers covered at room temperature for up to 3 days or refrigerate for up to a week.
- To reheat, microwave individual slices for 15-20 seconds for that fresh-baked warmth and gooey peanut butter.
Closing: This is one of those no-fail, pantry-friendly cakes that never disappoints—trust me, it’ll soon be your go-to for chocolate and peanut butter cravings alike!
