Step-by-Step Instructions

Prep Your Space:

Preheat oven to 325°F and position rack center. Thoroughly butter and flour mini Bundt pan ensuring you reach all the nooks and crevices. This careful preparation guarantees your cakes will release perfectly without breaking.

Infuse Flavor:

Pour bourbon into small bowl. Carefully split vanilla bean lengthwise and scrape seeds directly into bourbon. Stir thoroughly allowing those tiny flavorful specks to disperse evenly throughout the liquid creating an aromatic flavor base.

Combine Dry Ingredients:

Whisk flour cornstarch baking powder baking soda and salt in medium bowl until uniformly combined. This even distribution ensures consistent leavening throughout your cakes preventing any pockets of bitterness.

Create Butter Base:

Using electric mixer beat butter sour cream and sugar in large bowl for 3 to 5 minutes until mixture becomes noticeably lighter in both color and texture. This extended beating incorporates air creating essential structure.

Incorporate Eggs:

Add eggs and egg yolk one at a time beating for about 30 seconds between each addition until completely incorporated. Add bourbon vanilla mixture and beat until fully combined scraping sides of bowl as needed.

Build Batter Structure:

Add dry mixture in 2 additions alternating with milk beating on low speed just until blended after each addition. Overmixing at this stage develops gluten causing tough cakes, so mix just until flour disappears.

Create Marbling Components:

Divide batter evenly between two bowls. In one bowl add cocoa powder and milk mixing gently until fully incorporated maintaining a smooth consistency without overworking the batter.

Layer For Marbling Effect:

Spoon first layer of vanilla batter into prepared pans filling about one third full. Follow with layer of chocolate batter then top with remaining vanilla. Use a butter knife to gently swirl batters together with just two or three passes creating distinct marbling without overmixing.

Bake To Perfection:

Bake mini bundts for 20 to 25 minutes until tops spring back when lightly touched and tester inserted near center comes out clean or with just a few moist crumbs. Avoid overbaking which dries out these delicate cakes.

Cool Strategically:

Allow cakes to cool in pan on wire rack for exactly 10 minutes. This timing allows cakes to set but not stick. Carefully invert bundts onto rack and cool completely before glazing.

Prepare Chocolate Glaze:

Melt chocolate over low heat stirring constantly to prevent scorching. Stir in cream until perfectly smooth and glossy. Transfer to piping bag for precise application.

Create Vanilla Glaze:

Whisk confectioners sugar and milk until completely smooth adjusting consistency as needed. Mixture should coat back of spoon and drizzle slowly.

Final Assembly:

Drizzle chocolate glaze over cooled bundts followed by vanilla glaze creating decorative pattern. Allow glazes to set for about 30 minutes before serving.

Pin it

The vanilla bean is truly the star ingredient here. I discovered its importance when making these for my grandmother's 90th birthday. I had run out and used extract instead. While still good, she immediately noticed the difference and gently suggested I "never skip the real vanilla again." That memory makes me smile every time I split a vanilla bean for this recipe.

Storage Secrets

These mini bundts actually improve with a day of rest as flavors meld together. Store at room temperature in an airtight container for up to 3 days. For longer storage, freeze unglazed cakes wrapped individually in plastic wrap and placed in freezer bags for up to 3 months. Thaw completely at room temperature before glazing. The glaze sets firmly enough for stacking with parchment paper between layers, making these perfect for gifting or transporting to events.

Flavor Variations

While the vanilla chocolate marble is classic, this versatile base recipe welcomes creative adaptations. Replace the bourbon with orange liqueur and add orange zest to the vanilla portion for a citrus twist. Substitute the chocolate portion with 2 tablespoons of matcha powder mixed with a tablespoon of milk for an elegant green tea variation. During holiday season, I add 1/2 teaspoon of peppermint extract to the chocolate portion and crushed candy canes on top of the glaze for a festive touch that never fails to impress guests.

Troubleshooting Tips

If your mini bundts stick despite greasing and flouring, try using a baking spray with flour specifically formulated for intricate pans. Cooling exactly 10 minutes is crucial too short and they fall apart, too long and they stick. For the perfect glaze consistency, start with less liquid than called for and gradually add more until you reach the desired drizzling thickness. If your marbling looks muddy rather than distinct, you likely swirled too much remember that less is more with marbling technique.
