Everything You Need for Peanut Butter Swirled Strawberry Cake

When it comes to baking, choosing the right ingredients can make all the difference. This Peanut Butter Swirled Strawberry Cake relies on simple yet effective components that work harmoniously together. The key players include all-purpose flour for structure, granulated sugar for sweetness, and, of course, fresh strawberries that offer a burst of fruity flavor. The addition of peanut butter creates that creamy swirl we all crave, while buttermilk keeps the cake moist and tender. Let’s take a closer look at what you’ll need:
- 1 cup all-purpose flour + 1 tablespoon for tossing with strawberries: This is the foundation of your cake. The flour provides structure and stability, ensuring your cake rises beautifully.
- ¾ cup granulated sugar: Sweetness is essential, and this sugar will give your cake that delightful taste without being overly sweet.
- 2 teaspoons baking powder: This leavening agent helps the cake rise, creating a light and fluffy texture.
- ½ teaspoon cinnamon: A hint of warmth from the cinnamon enhances the overall flavor of the cake.
- Pinch of salt: Salt enhances all the flavors and balances the sweetness.
- 1 large egg: This acts as a binder and adds richness to the cake.
- ½ cup buttermilk: Buttermilk makes the cake moist and tender, giving it a wonderful texture.
- â…“ cup thick, full-fat Greek yogurt or sour cream: Both options add a creamy richness and help with moisture.
- 3 tablespoons canola or vegetable oil: This adds moisture and keeps the cake tender without making it greasy.
- 1 teaspoon vanilla extract: A splash of vanilla enhances the cake’s flavor profile.
- 16 ounces strawberries, halved or quartered: These juicy berries bring a fresh, fruity flavor that pairs wonderfully with peanut butter.
- ¼ cup creamy peanut butter, melted: This is the star of the show, creating that luscious swirl and adding a nutty richness.
How to Prepare Peanut Butter Swirled Strawberry Cake

Making this Peanut Butter Swirled Strawberry Cake is a delightful experience that fills your kitchen with amazing scents! With clear steps and a little patience, you’ll have an incredible cake that’s perfect for any occasion. Let’s dive into the process.
- Preheat your oven to 350 degrees Fahrenheit. While the oven warms up, grab an 8-inch square pan and line it with aluminum foil. This makes for easy removal later! Spray the foil with cooking spray to prevent any sticking.
- In a large mixing bowl, whisk together 1 cup of flour, ¾ cup of sugar, 2 teaspoons of baking powder, ½ teaspoon of cinnamon, and a pinch of salt. This dry mixture will be the base of your cake, so make sure to combine everything well.
- In a separate smaller bowl, whisk together your wet ingredients: 1 large egg, ½ cup of buttermilk, ⅓ cup of Greek yogurt, 3 tablespoons of oil, and 1 teaspoon of vanilla extract. This mixture brings moisture and richness to the cake.
- Now, add the wet mixture to the dry ingredients. Use a spatula or spoon to mix lightly until just combined. It’s okay if it’s a bit lumpy; you don’t want to overmix here!
- In another small bowl, toss the strawberries with 1 tablespoon of flour. This helps keep them suspended in the batter instead of sinking to the bottom as it bakes.
- Gently fold the floured strawberries into the batter. If you’re using frozen berries, there’s no need to thaw them! Just add them straight to the mix. For fresh berries, be aware that they will release less moisture, so adjust your baking time accordingly.
- Turn the batter out into your prepared pan and spread it evenly. Now it’s time to melt the peanut butter! Place it in a small microwave-safe bowl and heat it for about 30 seconds until melted.
- Drizzle the melted peanut butter over the top of the cake batter. Using a toothpick or a skewer, gently swirl the peanut butter into the batter. Don’t overdo it; you want to see some lovely swirls!
- Place the pan in the preheated oven and bake. I suggest keeping an eye on it, especially after 40 minutes. You’re looking for the center to be slightly domed and golden, with a toothpick inserted coming out clean or with a few moist crumbs.
- Once baked to perfection, remove the cake from the oven and place it on a wire rack to cool for at least 30 minutes. This cooling step is crucial for the cake to set properly. Optionally, you can drizzle more peanut butter over the top or serve it with a glaze if you’re feeling fancy!
Things Worth Knowing
- Watch for doneness: Every oven is different. Test with a toothpick rather than relying solely on baking time.
- Cooling time matters: Allow your cake to cool fully to avoid it falling apart when slicing.
- Using frozen strawberries: They can help keep your cake moist, but thawing them will change the texture.
- Don’t skip the flour for strawberries: Tossing them in a bit of flour prevents sinking and makes for a prettier cake.
