Ingredients
- 2 large eggs
- 3/4 cup vegetable oil
- 1/2 cup (100 g) granulated sugar
- 2 tsp pure vanilla extract
- 1 cup (120 g) all-purpose flour
- 1/2 cup (46 g) oat flour
- 1/3 cup chocolate protein powder
- 1 1/2 tsp baking powder
- 1/2 cup plain whole milk yogurt
- 1/2 cup (1 stick) unsalted butter, softened
- 1/2 cup creamy peanut butter
- 2 cups (226 g) confectioners’ sugar
- 1/2 tsp kosher salt
- 1 cup maple syrup
- 3 tbsp unsalted butter
- 2 tbsp heavy cream
- 3 tbsp vanilla protein powder
- Crushed roasted unsalted peanuts, for topping
Instructions
- Step 1: Arrange a rack in the center of your oven and preheat to 350°F (175°C). Line a standard 12-cup muffin tin with paper liners.
- Step 2: In a large bowl, whisk together the eggs, vegetable oil, granulated sugar, and vanilla extract until smooth.
- Step 3: In a medium bowl, whisk the all-purpose flour, oat flour, chocolate protein powder, and baking powder together.
- Step 4: Add the dry ingredients to the egg mixture and stir just until a few dry streaks remain. Add the yogurt and mix until combined and the batter is smooth.
- Step 5: Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full.
- Step 6: Bake for 15 to 20 minutes, or until a toothpick inserted into the center comes out clean. Remove from oven and let cool completely.
- Step 7: For the buttercream, beat the softened butter and peanut butter in a medium bowl using a handheld mixer on medium-high speed until creamy.
- Step 8: Gradually add the confectioners’ sugar, half a cup at a time, beating to blend after each addition. Add the kosher salt and continue beating until light and fluffy.
- Step 9: In a small saucepan over medium heat, bring the maple syrup and 3 tablespoons butter to a gentle boil. Stir occasionally and cook until slightly reduced, about 2 to 3 minutes.
- Step 10: Reduce heat to low and stir in the heavy cream. Remove from heat and whisk in the vanilla protein powder until smooth. Let the caramel cool slightly.
- Step 11: Using an apple corer or small spoon, carve out a small section from the center of each cooled cupcake.
- Step 12: Spoon or pipe a small amount of caramel into each hollowed center. Then pipe or spread the peanut butter buttercream over the top, covering the filling completely.
- Step 13: Sprinkle crushed roasted peanuts on top and drizzle with additional caramel if desired.
Tips & Variations
- For extra flavor, toast the peanuts before crushing to deepen their nuttiness.
- Substitute oat flour with almond flour for a different texture and flavor.
- The caramel and buttercream can be made up to one week ahead and stored in the refrigerator.
- Use a piping bag fitted with a star tip for a decorative buttercream finish.
Storage
Store cupcakes in an airtight container in the refrigerator for up to 5 days. Bring to room temperature before serving for the best flavor and texture. To reheat, warm gently in the microwave for 10–15 seconds if desired.

- Combine Dry Ingredients: In a separate medium bowl, whisk together the all-purpose flour, oat flour, chocolate protein powder, and baking powder ensuring they are evenly mixed.

- These cupcakes can be stored in an airtight container at room temperature for up to 2 days or refrigerated up to 5 days.
- To keep the caramel sauce smooth, stir gently before reheating and avoid boiling it again to prevent crystallization.
