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 the oven and preheat to 350°F (175°C). Line a 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 separate medium bowl, whisk together the all-purpose flour, oat flour, chocolate protein powder, and baking powder.
- Step 4: Add the dry ingredients to the wet mixture and stir until only a few dry streaks remain. Fold in the yogurt until the batter is smooth.
- Step 5: Divide the batter evenly among the prepared cupcake cups, filling each about three-quarters full.
- Step 6: Bake for 15 to 20 minutes, until a tester inserted in the center comes out clean. Remove from oven and let cool completely.
- Step 7: For the buttercream, beat the softened butter and peanut butter together in a medium bowl using a handheld mixer on medium-high speed until creamy.
- Step 8: Gradually add the confectioners’ sugar in 1/2 cup increments, beating well after each addition. Add the kosher salt and continue to beat until light and fluffy.
- Step 9: To make the caramel, combine maple syrup and butter in a small saucepan over medium heat. Bring to a gentle boil and cook, stirring occasionally, for 2 to 3 minutes until slightly reduced.
- Step 10: Reduce the heat to low, stir in the heavy cream, remove from heat, then whisk in the vanilla protein powder until smooth. Let the caramel cool slightly.
- Step 11: Using an apple corer or a small spoon, carefully carve out a small section from the center of each cupcake.
- Step 12: Spoon or pipe a small amount of the caramel into each hollowed cupcake center.
- Step 13: Pipe or spread the peanut butter buttercream over the top of each cupcake, covering the caramel-filled center completely.
- Step 14: Sprinkle crushed roasted peanuts on top and drizzle with additional caramel sauce for garnish.
Tips & Variations
- For a nut-free version, substitute sunflower seed butter for peanut butter and omit the peanuts topping.
- Use chocolate or vanilla protein powder depending on your flavor preference.
- Make the buttercream and caramel up to a week ahead for easier assembly on baking day.
- Chill cupcakes slightly before taking out the centers to make carving easier and prevent crumbling.
Storage
Store assembled cupcakes in an airtight container in the refrigerator for up to 4 days. Bring to room temperature before serving for best flavor. Buttercream and caramel can be stored separately in airtight containers in the refrigerator for up to one week. Reheat caramel gently before using.

FAQs
Can I use all-purpose flour instead of oat flour?

- 1/2 tsp kosher salt
Caramel
- 1 cup maple syrup
- 3 tbsp unsalted butter
- 2 tbsp heavy cream
- 3 tbsp vanilla protein powder
Topping
- Crushed roasted unsalted peanuts, for topping
Instructions
- Prep the oven and muffin tin: Arrange a rack in the center of your oven and preheat it to 350°F (175°C). Line a standard 12-cup muffin tin with paper liners to prepare for the batter.
- Mix wet ingredients: In a large bowl, whisk together the eggs, vegetable oil, granulated sugar, and vanilla extract until the mixture is smooth and well combined.
- Combine dry ingredients: In a separate medium bowl, whisk together the all-purpose flour, oat flour, chocolate protein powder, and baking powder to evenly distribute the leavening and protein powder.
- Make the batter: Gradually add the dry ingredients to the wet ingredients, mixing until only a few dry streaks remain. Then fold in the whole milk yogurt until the batter is smooth and uniform.
- Fill the cupcake liners and bake: Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full. Bake for 15 to 20 minutes or until a tester inserted in the center comes out clean. Remove from oven and let cool completely.
- Prepare the buttercream: In a medium bowl, using a handheld mixer at medium-high speed, beat the softened unsalted butter and creamy peanut butter together until creamy and smooth.
- Add sugar and salt to buttercream: Gradually add the confectioners’ sugar, half a cup at a time, beating well after each addition to fully incorporate. Stir in the kosher salt and continue beating until the buttercream is light and fluffy.
- Make ahead tip for buttercream: Buttercream can be made up to one week in advance. Store it in an airtight container refrigerated, and bring to room temperature before decorating.
- Prepare the caramel: In a small saucepan over medium heat, combine the maple syrup and unsalted butter. Bring to a gentle boil and cook, stirring occasionally, until slightly reduced and thickened, about 2 to 3 minutes.
- Finish the caramel: Reduce heat to low and stir in the heavy cream. Remove from heat and whisk in the vanilla protein powder until the caramel is smooth. Allow to cool slightly before using.
- Core the cupcakes and fill: Using an apple corer or a small measuring spoon, carefully carve out a small section from the center of each cooled cupcake. Spoon or pipe a small amount of the prepared caramel into each cavity.
- Frost the cupcakes: Pipe or spread the peanut butter buttercream over the top of each cupcake, covering the filled center to seal in the caramel.
- Add finishing touches: Sprinkle crushed roasted unsalted peanuts on top of each frosted cupcake for extra crunch. Drizzle with additional caramel for a glossy, decadent finish.
- Make ahead tip for caramel: Caramel can be made up to one week ahead. Store it in an airtight container in the refrigerator and bring to room temperature before use.
Notes
- The buttercream and caramel can both be made ahead to save time on the day of serving.
- Use an apple corer or a small spoon to easily hollow out the cupcake centers for filling.
- Ensure your protein powders are fresh and not clumpy to maintain a smooth batter and caramel.
- For a dairy-free version, substitute yogurt and butter with plant-based alternatives and use a non-dairy cream for the caramel.
- These cupcakes freeze well once assembled. Thaw at room temperature before serving.
