👩🍳 Step‑by‑Step Instructions
- Prepare slow cooker
Lightly grease a 4–6 quart crock with butter or oil. - Slice cake
Cut into 1‑inch slices (halve if tall). - Arrange cake
Lay slices snugly in the slow cooker, overlapping slightly if needed. - Mix tres leches
Whisk whole milk, condensed milk, evaporated milk, and vanilla until smooth. - Soak cake
Pour mixture evenly over cake slices. Press gently so cake absorbs liquid. - Cook low and slow
Cover and cook on LOW for 2–3 hours. Cake should look glossy, custardy, and mostly absorbed with a little liquid at edges. - Rest and set
Turn off slow cooker, uncover, and let rest 20–30 minutes. This allows liquid to fully soak in for that melt‑in‑your‑mouth texture.
✨ Creamy, indulgent, and effortless—this slow cooker tres leches cake is proof that the simplest methods can deliver the most unforgettable desserts.
